2 PRESENTATION
2.1 General description The MICRO-HITE 2016 height gauge range is different from any other height gauge as it offers an exceptional performance as well as intuitive and easy use.
This autonomous measuring instrument is designed for measuring lengths such as external, internal, step, height or depth dimensions as well as distances. Its concept also enables measurements of form and orientation tolerances such as straightness or perpendicularity errors.
A cast-iron base (No. 10) including a hardened stainless steel plate supports the
instrument. Three resting points guarantee the stability of the height gauge (see here ).
The integrated electric pump (No. 12) generates the air cushion so that your height gauge can easily be moved across the granite table.
The rigid vertical column under the protective housing (No. 17) includes the guiding part that is rigorously straight and perpendicular to the base.
A measuring head slides on the guiding element, while the optoelectronic measuring system (patented by TESA) measures any head displacement.
Each height gauge is used with a control panel (No. 14) with numerous calculation possibilities offering a measuring solution adjusted to each application.
Therefore, each instrument features several patented technologies, which makes it a reliable and unique tool that can be used by any operator.

Instruction manual for MH & MH+M
2.2 Instrument base The base is chemically nickel-plated in order to make it very resistant to corrosion. Its lower face, which has been machined to ensure that is rigorously flat, includes three finely-machined support lugs (air bearings) that guarantee the stability of the height gauge.
These lugs form a large surface so that any grooves or other similar irregularities on the granite table can be easily cleared.
The faces (9) defined by the red zones in the schema below are specially designed to support the instrument against a parallel gauge block or for guiding it along such a block.
2.3 Air cushion The air cushion, which is generated by an integrated electric pump, allows the height gauge to be easily moved on the granite table. The height gauge can then be moved effortlessly and any wear created by friction is avoided.
11
Instruction manual for MH & MH+M
This pump is activated by pushing a control button, which immediately activates an air cushion between the instrument and the granite table (violet zone below), which is only a few microns thick.
2.4 Vertical column
The thickness of the air cushion can be adjusted according to the quality of the granite table.
You can adjust it via the control software (for further details, see this chapter ).
When measuring workpieces where the dimensions or weight don’t allow for any movement, the height gauge can be moved by using the air cushion.
Experience has shown that the air cushion should not be thicker than necessary. When it is activated, it has to support the weight of the instrument while still being slightly in contact with the granite table.
The rigid vertical column of the instrument is perpendicular to the cast-iron base, to which it is permanently fixed.
The perpendicularity of each instrument is adjusted mechanically in the factory using a patented TESA system, which makes it possible to use it for a reliable and quick control of perpendicularity.
The height gauge is adjusted for frontal as well as lateral perpendicularity measurements.
12
Instruction manual for MH & MH+M
2.5 Rotary control handle
On the MICRO-HITE+M models, a rotary control handle (FEEL&MOOVE patented system) is located close to the instrument base. It serves for guiding the instrument when it is moved on the air cushion and for starting the fast displacement of the probe as well as for triggering all main measuring functions (up or down probing, bore or shaft measurement).
The height gauge is very user-friendly with easy and precise handling. Any fast displacement, slow approach to the point to be measured, probing up and down or bore measurement can be carried out using this rotary control handle.
13
Instruction manual for MH & MH+M
14
In general, the following measuring functions can be executed directly via this rotary control handle, without the need to select the key on the keyboard of the control panel: , and
.
Definition of actions
Moving up
Turning the rotary control handle clockwise will move the probe up.
Moving down
Turning the rotary control handle counterclockwise will move the probe down.
Probe positioning
A continuous rotation of the rotary control handle accelerates the displacement of the probe progressively
(speed of displacement according to the rotation angle).
It will decelerate and then stop when approaching the zero point or when releasing the rotary control handle.
The rotation window between and is considered as the speed window that corresponds to the position of the probe.
Fast displacement
In case of a large distance between two points to be measured, you can move the probe in such way that the displacement time between two measurements is minimised. To do so, the rotary control handle features another graduation (from or to the end), which allows a fast displacement of the probe.
Probing up
One small and fast rotation (no need of a long rotation) of the rotary control handle to the right side will start probing up. The column will move up until the probe is in contact with the workpiece.
Instruction manual for MH & MH+M
2.6 Handwheel
Probing down
Same as for probing up.
Bore measurement
Activating the rotary control handle twice in the same direction allows bore measurement with detection of the culmination point.
•
When rotating clockwise, the measurement will start with probing the upper point of the bore.
•
When rotating counterclockwise, the measurement will start with probing the lower point of the bore.
When an automatic measurement process is started (not necessarily with the rotary control handle), it is possible to stop it by a short rotation/activation of the rotary control handle in the opposite direction of the one of the movement or by pressing one of the keys of the control panel keyboard.
On manual models, the main handwheel located above the base is the element that allows you to move the probe during a measurement.
2.7 Lever-type locking ring
The handwheel can include a fine adjustment system, which allows to adjust the displacement to the measurement of small elements. A manual MICRO-
HITE that does not include that system can be upgraded at any time with it.
For further information, please contact your local reseller.
This handwheel and the drive system it is linked to have been specially designed to allow the user to feel the different pressure on the probe and when the measurement is carried out.
The lever-type ring allows to tighten the drive of the measuring head, which can still be slightly moved.
15
Instruction manual for MH & MH+M
2.8 Electric power supply
2.9 Measuring system
This ring is mainly used for bore and axis measurements (static process) in order to allow the determination of the culmination point. It is also used to avoid any displacement of the carriage when the system is transported.
There are two different possibilities for supplying the instrument with power.
•
Via a power supply (TESA reference: 00760245)
•
Via a rechargeable removable battery (TESA reference: 00760244)
The battery simplifies working on the granite table as no power cable hinders the operator when displacing the height gauge.
The battery also supplies the panel connected to the instrument base with power.
It is important to always use the cable and power supply unit provided with the height gauge (TESA reference mentioned above). Not adhering to these instructions can lead to malfunction of your instrument or irreversibly damage it.
In case of questions, please contact your local reseller.
The height gauge features an optoelectronic measuring system digitally capturing the measured length, which is also called measurand (TESA patent). The glass scale with both incremental graduations and a reference mark serve as material measure. According to a principle of reflection, the scale is scanned by a sensor with no mechanical contact. The measuring signal is then transmitted to the control panel.
From the neutral position A, the system for determining the measured values can move in both directions up to the switch points. As soon as one of the two points is reached, it starts capturing and the information is sent to the control panel.
In order to guarantee that your height gauge is functioning correctly, it is important that the scale and the sensor remain free of any solid or liquid particles that could impede the functioning of the scale.
The distance C, which is symmetrical to the position of the relevant trigger point, is only used for detecting the culmination point when probing cylindrical circular surfaces (for further details,
The system for obtaining the measured values can be moved from the neutral position up to the spring-loaded end stops via the distance D. However, too much pressure will lead to an invalid measurement of the point.
16
Instruction manual for MH & MH+M
On the manual MICRO-HITE, the probing force (and therefore the position of the probe on the measuring carriage) is visible through a coloured bar on the right side of the screen. At any moment, when the probe comes in contact with the workpiece to be measured, this bar is activated and changes its colour according to the applied pressure.
When the probe touches the piece, the bar on the right displays a unique horizontal black mark.
This mark corresponds to the minimum required pressure in order to have a single probing be taken. If the pressure is not high enough, the bar colour is orange. When the mark has been passed by the displayed force, the colour becomes green or even red if the pressure is too high.
Two horizontal lines are also displayed in the middle of the bar. They represent the ends of the measurement zone defined by letter C in the table below.

2.10 Control panel
Instruction manual for MH & MH+M
The control panel has been developed as ergonomic and intuitive as possible. Its keyboard is separated in 4 different zones each focusing on particular actions.
2.11 Fixing arm
For further details, see this chapter .
As all environments the instrument is used in are different, your system includes a flexible control panel support, which offers you two degrees of freedom through adjustable screws.
Then it is possible to:
•
adapt the angle of the screen for easier reading
•
position the control panel for an ideal ergonomic use
18
Instruction manual for MH & MH+M
2.12 Information LED For more comfort during measurements, an informative LED has been placed at the end of the probe support mounting shaft. This LED changes its colour according to the current action and the measurement pertinence.
2.13 Interface &
displayed values
This system developed by TESA is patented.
For further details, see this chapter .
The ergonomic software has been designed to avoid any ambiguous situations. At any time, the displayed values correspond only to a measurement or a calculation and never to the probe position (except in mode “scanning” or Max, Min, Δ ).
2.14 Printer
Results of last measurement in red, previous measurement results in green.
In order to avoid any reading errors of the displayed values on the screen, only measurement results or calculations are visible. Except for a few specific modes, your height gauge will not display the current value of the position of the probe.
An USB matrix printer especially designed for your height gauge is available as an optional accessory.
Its installation does not require any special intervention. Each MICRO-HITE or MICRO-
HITE+M is directly compatible with this printer, which can be connected to an USB port on the back of the control panel at any time.
19
Instruction manual for MH & MH+M
2.15 Connectors
For further details on the printer installation, see this chapter
. For its use, see this chapter .
The control panel features several connectors allowing to manage the obtained data. Besides three USB connectors on the top of the back, there is also a TLC (TESA Link Connector) IP65 connector, which enables you to send data to an external device.

Measurements
•
The measuring face of the step gauge block, which is approximately at the same height as the reference surface of the granite plate, is the reference point for measurements.
•
The reference point is captured once (probing down) and is valid for the following three series of measurements.
•
For each series, the measurements of the step gauge blocks are carried out with regular nominal distances of 20 mm (see calibration certificate).
•
The measurements are carried out with inversion of the probing direction. This means that the measuring faces of the step gauge blocks are probed alternately up and down until the end of the measuring range of the instrument is reached.

is identical to the one above, except that parameters
A and B are replaced by C and D. It is also possible that the technical specifications of certain products indicate A = C and B = D.
The MICRO-HITE and MICROHITE+M are instruments with a “fixed zero”.
This means that in order to have measuring results in accordance with the specifications indicated by the maximum permissible error, the reference used in a measurement sequence has to be measured on the granite table generally used for most applications.

5 INSTALLATION, SECURITY & MAINTENANCE
5.1 Location
5.2 Place of use
5.3 Lighting
The instrument has to be installed in a location satisfying the general required conditions, but also the specific and very precise conditions regarding the environment, power supply, etc. It is essential to be able to identify important factors and to correctly prepare the zone the instrument is installed and used in.
In order to use the instrument correctly, the following precautions have to be taken into account:
•
Avoid placing the instrument close to a window, door, cooling or heating system.
•
Avoid causing recurrent temperature variations due to direct exposure of the instrument to the sun.
•
Avoid installing it close to other machines that could induce large electromagnetic fields.
Use indirect or fluorescent light. Avoid direct exposure to the sun or any other strong light.
5.4 Measuring surface Choose a surface free of any vibrations that could lead to measurement or reading errors despite the stability of the mechanical and electronic components.
Make sure that the surface can carry the weight of the machine and the workpiece to be measured. Ideally, the surface should not have any splits or joints.
It is recommended to use a measuring surface that is big enough to enable smooth and easy
5.5 Cleanliness movements of the instrument around the workpiece to be measured if the latter cannot be displaced manually.
Make sure that the floor surface is clean, so that there is no dust, condensation or metal filings.
The supports and scales have to be perfectly clean without any oily particles on it.
5.6 Vibrations
5.7 Electric power supply
Floors of companies are constantly at risk of vibration due to different reasons:
CNC and other machines, transportation vehicles and any other source of vibrations. These vibrations can directly influence the metrological performances of the machine.
Stability
When the instrument is powered electrically via the cable connected to the network, make sure that the electric power supply of the machine is as stable as possible, as it could otherwise deteriorate the system. If the electric network the machine is connected to does not provide sufficient stability, it is highly recommended to use an additional device to avoid any damage. These devices can be found locally.
Power cable
Do not use any other power cable than the one provided with the instrument.
Transformer
Do not use any other transformer than the one provided with the instrument.
Voltage
Do not use the instrument with any other voltage than the one indicated in this manual.

This option is useful when using the height gauge with a footswitch (a hand switch is also possible). The foot switch is a quick and easy way of getting the hands free to handle the part to be measured, when for example a batch must be controlled. This foot switch can be set in two different ways:
•
Transmission of data: It acts in the same way as the button of the panel
•
Last measurement action: allows to execute infinitely the last action of the performed measurement (often a measurement action for the
MH+M)
Once a sequence has been created, it is often necessary to insert tolerances for each measured dimensions. To allow the user to be faster, the nominal value for each of the program block is calculated from the corresponding measured value. This calculation is made from the help of this option (rate) which is the mean for the software to clarify the way the values have to be rounded. Note it is always possible to edit an automatically calculated nominal value later.

10.2 Automatic process
(MH+M)
The probe support (2) is directly linked to a carriage system with an opto-electronic sensor
(7) on it. As soon as the instrument has been turned on, this non-contact sensor will read the incremental divisions (8) on the glass scale (9) at all times. One of these increments is considered as the reference from which the height gauge will always calculate its position.
This mark is called the reference mark (6).
The initialisation process therefore consists in moving the sensor in front of the reference mark, which is located approximately at 15 cm from the instrument base.
10.3 Manual process
(MH)
Once the height gauge is turned on and the software is loaded, the initialisation page is accessed and the height gauge automatically starts to search the reference mark. It will first move up approximately 15 cm. If the reference mark is not found or the upper limit of the instrument is reached, the sensor will move down. The process is finished once the sensor has detected the reference mark on the glass scale.
56
Instruction manual for MH & MH+M
The concept is the same for manual height gauges. However, the user has to move the probe
(and also the sensor integrated in the instrument) himself in order to detect the reference mark on the glass scale.

11 DETERMINATION OF THE PROBE CONSTANT
11.1 Masterpiece Each height gauge is provided with a standard, also called master piece.
It is necessary to use this accessory with most of the measurement modes integrated in the MICRO-
HITE and MICRO-HITE+M height gauges.
11.2 Concept
Calibration with groove of the master piece
Calibration with rib of the master piece
The master piece has to be as clean as possible when it is used, as it is, to a large extent, the measurement of this tool that will determine the accuracy of the results obtained later.
In order to allow the user to carry out measurements without any time-consuming calculations, the constant of the probing system is determined on the master piece, whose dimension is known. By combining 3 standards of which it is constituted, it represents an internal or external dimension of
12.7 mm / .50000 in.
It is important to only use the master piece provided with the height gauge. TESA do not guarantee correct functioning of the instrument if it is used with another master piece than the one provided by default.
The final inspection and the certificate of the instrument both refer to this master piece.
When measuring elements that require probing in two directions (for further details, see this
chapter ), it is necessary to take into account the probe constant.
Elements that require two probe hits: bore, axis, groove, rib
58
Instruction manual for MH & MH+M
The probe constant is a permanent correction factor. It is calculated by the control panel after master piece measurements, then saved and automatically taken into account during the next measurements.
The probe constant considers and compensates the main influencing factors such as:
•
Diameter of the used ball or disc probe
•
Elastic deformation of the probe and its support due to the measuring force
•
Hysteresis error of the measurement system
Each time the measurement conditions change, the probe constant has to be determined again. The main causes of modification are:
•
Turning off the instrument
•
Probe change
•
Probe position modification
•
Measurement mode change
In case the measurement sequence does not require the use of the probe constant (for further
all values are offseted from the radius of the probe. This is the ST1 mode.
H1 = H2
If probing in two directions is accepted in the same measurement sequence, this is the case in particular thanks to the compensation of the ball-tip radius in the probing direction. This is the ST2
mode.
Without compensation of the ball-tip, the displayed value in the case below would be H2, although the required value is H1.
H2 ≠ H1
Schema representing the compensation of the ball-tip:
59
Instruction manual for MH & MH+M
11.3 Procedure
In order to determine the right point, each height H1 is recalculated according to H2 (which corresponds to the centre of the ball-tip) and the radius R of the insert (defined when detecting the probe constant).
There are several processes to determine the probe constant. The TESA master piece design has been thought to minimise the determination time and avoid any errors that could occur when moving the master piece during a sequence.
The calibration procedure of the probe (or determination of the probe constant) requires at least two probe contacts for each measurement point.
11.4 Steps
The difference between the two values obtained for each point cannot exceed a maximum value that depends on the selected resolution. If it is higher than this limit value, the difference is displayed. The user then has the choice to accept it and bypass the process with or to restart the process for a new measurement.
If the user accepts the result, the number of digits after the comma will be reduced to be in line with the probe constant.
60
Each time the procedure for determining the probe constant is started, the above page is automatically displayed.
If you are using a motorized height gauge, a warning message will be displayed.
Before activating the process for automatic determination of the probe constant, the insert must be positioned at the height of the master piece. As this displacement is done automatically, the following message will be displayed to avoid any collision with another object:
Instruction manual for MH & MH+M
This example shows a page presenting a procedure defined for a motorised MICRO-HITE+M height gauge. When using a manual instrument, the points have to be measured using the handwheel and moving the probe from top to bottom.
If the instrument is motorised, the procedure can be started clicking on on the keyboard or on the screen.
When using a motorised instrument, the insert is automatically positioned at the height of the centre of the reference when the user activates the process for determining the probe constant. This height can be configured in the system options .
The groove measurement process is active by default. Most of the time, measurements are carried out using a ball probe. However, if the user wants to define the probe constant by measuring the rib of the master piece, the user first has to change the mode by pressing the key .
61
Instruction manual for MH & MH+M
Definition of keys
Change the process for a definition of the probe constant using the rib of the master piece.
Change the process for a definition of the probe constant using the groove of the master piece.
Once the process is finished and the probe constant defined, a calibration block is automatically created in the measurement list of the mode. The measurements can then start in ST2 mode.
The next step is to define the reference as shown in the following image.

12 PRINCIPLES OF MEASUREMENT
12.1 Generality
12.2 Probe support
Before using the MICRO-HITE or MICRO-HITE+M height gauge, it is important to remember that the way in which the values are measured is determined by the measurement problem. It is essential, that the user can define the nature of the measurement process according to the application, in order to quickly get reliable results.
In general, it is important to ask yourself the following basic questions:
•
Does the measured value require a single or double probe hit?
•
Does the measurement require an inversion of the probing direction?
•
Do you have to measure with or without detection of the culmination point?
•
Does the measurement sequence have to take into account only one (1D) or two coordinates (2D)?
•
Which accessory fits the most with the desired measurement?
These questions are the first step to guarantee ease of measurement with correct metrological results.
It is very likely that during the use of the height gauge, the type of application the user will be confronted will imply accessories changes in order to guarantee a reliable and precise measurement. Mounting or removing a probe or probe support is a process that requires to be careful and done in a correct way. Indeed, not mounting it correctly could lead to significant measurement errors.
12.3 Measurement
modes
In order to guarantee the reliability of the measured values, it is necessary that the following condition is met: the probe 1 has to be firmly attached to the probe holder 2, which is fixed on the mounting shaft 3. Make sure that the two screws of the probe holder 4 and 5 are tightened. This procedure is the same for all types of probes and supports.
Once the workpiece and the wanted dimensions to be measured are known, the user has the possibility to choose among several modes:
ST1
Measurement with unidirectional probing
ST2
Measurement with bi-directional probing
MAX, MIN, Δ
63
12.4 ST1 & ST2
philosophy
Instruction manual for MH & MH+M
Detection parallelism errors
PERPENDICULARITY
Measurement of perpendicularity and straightness errors
ANGLE
Angle measurement
CALCULATOR
Allows you to calculate by manually entering the values or using the results of previous measurements.
The two main modes integrated in the height gauge range are defined by the names ST1
and ST2 . These are the most frequently used modes. They can directly be selected via the main menu of the measurement software, which can be displayed at any moment by pressing key .
The major difference between these two measurement modes is closely linked to the features (height, diameter etc.) that will be determined during one measurement sequence.
The determination of certain features does not require an inversion of the probing direction, while others entirely depend on it.
Mode Description
ST1
•
Lengths measurement in only one probing direction.
•
The calibration of the probe is not necessary.
ST2 •
Lengths measurement in two probing directions.
•
The calibration of the probe is mandatory.
Each one of the two modes has been developed in order to best suit the different application cases and possibilities of use. The flexibility of mode ST2 allows you to measure any elements, while ST1 mode minimises the time of access to the measurement
(avoiding the probe calibration process) and allows you to use accessories that cannot be easily calibrated with the master piece.
64
Instruction manual for MH & MH+M
Measurement without inversion of probing direction
In the above examples, all heights are measured by down hits. All measurements therefore have a similar probing direction.
12.5 Measurement
functions
Measurement with inversion of probing direction
The above examples show that the measured elements require two hits, one by pushing upward and one downward. This is called a measurement that requires an inversion of probing direction as the two measurements have an opposite direction.
The list of measurement functions is defined by two types of keys:
•
Action keys (single or double probing)
•

12.6 Manual single
probing (MH)
Average between two values (H)
Manual probing with one hit corresponds to the measurement of a height by establishing contact between a probe and a flat surface. This process depends on the user, as they have to move the probe at all times using the handle provided for that purpose.
In noisy environments, the beep tone is often not loud enough to provide clear information during the measurement. The LED located on the shaft of the probe support gives you this information visually and close to the measurement.
67
68
Instruction manual for MH & MH+M
Process
1. Move the probe using the handwheel. Make sure you do not hit anything (probe, probe support etc.) during the movement.
2. Position the probe close to the point to be measured.
3. Once the location of the measurement is clearly defined, put the probe in contact with the surface. Continue to apply pressure on the insert (and make sure that the strain gauge is still in the green zone) until the point is captured.
4. Release the system, so that the probe is not in contact with the workpiece any more.
5. Visualise the result on the screen.
Instruction manual for MH & MH+M
12.7 Automatic single
probing (MH+M)
Note that a single probing block is created with the icon (or ).
6. Proceed the same way for the next measurements, regardless of the probing direction.
The automatic single probing process is completely automatic, once the user has chosen an action from the control panel keyboard or via the displacement handle.
Process
1. Position the probe close to the zone to be measured using the handle on the measuring carriage or the rotary control handle.
2. Make sure that there is no element between the probe and the zone to be measured that could impede the displacement of the probe.
3. Start the measurement by activating the key , or start the measurement directly using the rotary control handle (chapter 2.5).
4. As soon as the probe gets in contact with the point to be measured, the system ensures a constant probing force. After a stabilisation period, the measurement will be saved and then displayed on the control panel. The LED lights up briefly at the same time as the beep that indicates the end of the measurement.
69
Instruction manual for MH & MH+M
5. As soon as the measurement is finished, the probe will automatically retract. The retract distance is defined in the system parameters.

6. Proceed the same way for the next measurements.
The concept of the static detection of the culmination point is defined by its way of determining the max. or min. height of the selected bore or axis. Unlike the procedure
described here, the displacement of the workpiece back and forth is only used to position
the probe at the centre of the element. At this time, no measurement is carried out. The workpiece is no longer moved (static measurement). At that moment, the culmination point(s) are measured by probing up/down.
Before starting the procedure, it is important to make sure that the “static measurement” option has been correctly configured in the system options .
Process
1. Place the probe inside the bore.
2. Displace slightly the probe to one side in order to locate visually on one side of the searched culmination point.
3. Move the probe up or down in order to establish contact with the workpiece.

Instruction manual for MH & MH+M
4. Once the contact is established, continue to apply pressure in order to place the strain
gauge (see this chapter or this chapter) in the green zone. Ideally place the strain
gauge in the centre of the green zone in order to allow the measuring carriage to move correctly from one side of the culmination point to the other (maintaining the strain gauge always in this green zone).
5. Lock the locking ring. At that moment, the software will start the procedure to measure a culmination point.
The software remembers what was the selected process when calculating the last culmination point. This process is automatically enabled for the next measurement. If you would like to change it, you can press the key
or from the control panel.

•
The software requires to move the probe inside the bore
• The software activates the information LED in the probe’s zone
•
The software displays a graph helping with positioning
One of the graphs helping with positioning is displayed as follows:
This graph allows to display the minimum/maximum position in memory as well as the difference between the current probe position and this maximum/minimum value. This delta value enables the fine positioning of the probe when it is very close to the point to be measured.
Note that the key allows to change from one type of graph to another according to the user’s wishes.
6. The probe is now in contact with the workpiece, on one side of the culmination point.
The next step is to move in direction of the culmination point to be detected until the delta value increases (which means that the probe moves up in the bore, on the opposite side of the initial position regarding the culmination point).
Instruction manual for MH & MH+M
Note that the value of the culmination point in our example increases from 19.485 to
114.966. The probe is now at a distance of 0.02968 of the culmination height currently in memory (114.966).
7. The next step consists in moving the probe back in order to obtain the smallest difference possible of delta, which means that the probe is at the minimum value or very close to it.
8. A delta value close to zero indicates that the probe is at the minimum point.
9. The value of the minimum has not changed. The delta value is very low now.
73
Instruction manual for MH & MH+M
10. The next step consists of unlocking the locking ring and probing down, as the insert has been positioned at the culmination point.
12.9 Static culmination
point (MH),
galvanometer
The first steps of this procedure are equivalent to the ones defined in the previous chapter
(determination of the culmination point, static mode, bar graph). As steps 1 to 5 are same, the explanation of the procedure below will start at the moment the graph is displayed for the first time on the screen.
Note that the key allows to change from one type of graph to another according to the user’s wishes. The two other keys allow you to change the resolution of the galvanometer and to set the position of the pointer on its 0.
6. The probe is now in contact with the workpiece, on one side of the culmination point.
By default, the pointer is positioned on the 0 of the display. When the display is activated, its resolution is 20µm. The value 0.00206 corresponds to the height difference regarding the original position (which is 0).
74
Instruction manual for MH & MH+M
7. Displace the workpiece in order to move the probe in the direction of the culmination point to be detected.
As the workpiece (and therefore the probe) is displaced, the pointer of the galvanometer will also move.
If the probe has still not moved to the inflection point (which means that the pointer will turn and move in the opposite direction) and the pointer reaches the end of the display, you have to press the context-based action key in order to position the pointer in a visible range. Below you find an example of the pointer at the end of the display.
75
Instruction manual for MH & MH+M
Continue to use the key as long as you do not see any change of direction of the pointer as you are moving the workpiece.
8. When the insert passes the culmination point, the pointer of the galvanometer will change its direction of rotation and move in the opposite direction.
9. At that moment, you will know that you have passed the inflection point and that you have to move the workpiece in the opposite direction in order to go back to where the pointer modifies its direction again (ideally play with key to visually position the inflection point at 0 on the display).
10. Once you have detected the inflection point, the next step consists of unlocking the locking ring and probing down, as the insert has been positioned at the culmination point.
12.10 Static culmination point (MH), help
LED
The use of the LED during the process of determining a culmination point in static mode offers an advantage when looking for a reliable but quick measurement. The LED positioned at the limit of the shaft that is used to fix the probe support will change its colour according to the action that will be applied on the probe.
76
Instruction manual for MH & MH+M
For the explanation below, we consider that the LED option has been previously activated in the menu System options , which is available from the main page of the software that can be accessed at any time via the key .
There are four different colours that the LED will display. Each one of it represents different information.
Colour Description
The software is ready for measurement. The process can start.
The probe is moving in the wrong direction.
The probe is located at the inflection point or very close to it.
The probe is moving in the right direction.
Do not displace the workpiece too quickly.
Below you will find an example describing the different steps of measuring a minimum internal culmination point. Of course all other types of culmination points can be measured in a similar way.

In this precise case, the software expects to detect a minimum internal culmination point. If the workpiece is moved in a way, that the probe is pulled away from the culmination point, the LED will warn you about the incorrect handling.
The LED became red at step 5. Therefore, it is important to move the workpiece in the opposite direction in order to detect the inflection point. This is the correct direction and the LED becomes orange.
As long as the probe has not passed the inflection point and is not “going up” on the other side of the point to be measured, the software understands that the minimum point has not yet been determined. Therefore, it is important to continue to move the workpiece until the LED becomes red
(which is equivalent to saying that the probe is moving away from the culmination point).
Change the direction again. Carefully, you are approaching the zone of the culmination point.
12.11 Bore measurement, static mode (MH)
12.12 Dynamic culmination point
(MH)
9 As soon as you have reached the culmination point, the LED becomes green. Make sure you are at the right place by verifying the values displayed on the screen.
You can then unlock the ring and measure the culmination point.
10 - If you continue to move the measuring probe in any direction from the culmination point, the LED will become red again.
The measurement of a bore or axis follows the same steps as the procedure described
here. The only difference is that the determination of the bore or axis diameter requires a
probing up and a probing down instead of a single probing down as described in step 10.
Thus, mode ST2 is required as probing with two contacts up and down is required.
On the manual MICRO-HITE, a culmination point can be measured in dynamic mode meaning by moving the workpiece back and forth, so that the probe passes the maximum or minimum culmination point to be detected. The height of the culmination point is then measured on the fly and stored in the memory. Measurements in dynamic mode are only possible when the corresponding option has been configured in the system parameters
(for further details, see this chapter).
At each passage, a new culmination point is calculated and compared with the previous ones. If the difference between all the memorised points is above a certain limit, the measurement is considered as invalid.
Process
1. Place the probe inside the bore.
78
Instruction manual for MH & MH+M
2. Displace the probe slightly to one side of the culmination point (visually).
3. Move the probe up or down in order to establish contact with the workpiece.
4. Once the contact established, continue to apply pressure in order to place the strain gauge in the green zone. At that moment, the software has to detect that you want to measure a culmination point and will ask you to move in the bore.
If the selected mode is not the right one (bore instead of axis measurement, or vice versa), this is the moment to select the right procedure using the keyboard. Note that the procedure selected will be stored in the memory for the next measurement.
5. Once the minimum (or maximum) point passed, the software will issue a beep. The probe is now located on the opposite side.
6. It is now possible to release the pressure on the probe and to remove it from the workpiece. This action finishes the process.
79
Instruction manual for MH & MH+M
It is also possible to pass again and to move to the opposite direction again in order to define a new inflection point, which will be compared to the first one. This step can be repeated as often as you want until the pressure on the probe is stopped.
7. The result is automatically displayed on the screen.
12.13 Bore measurement, dynamic mode
(MH)
12.14 Culmination point (MH+M)
Bores or axes cannot be measured in mode ST1 with a manual MICRO-HITE, as it requires probing in two directions. Therefore, mode ST2 is required.
Once in mode ST2 , it is important to verify that the option of probing with two contacts
has been correctly selected (for further details, see this chapter ). Then proceed as
explained here for each upper and lower culmination point.
On the MICRO-HITE+M, the type of measurement of the culmination point is intrinsically defined by the selected keyboard action. The software knows the nature of the point to be measured from the selected process:
Minimum internal culmination point
Maximum internal culmination point
Minimum external culmination point
Maximum external culmination point

The dynamic mode is the only mode defining the process to determine culmination points with a motorised height gauge. It is the workpiece

2. Displace the probe slightly to one side of the culmination point (visually).
3. Select an action key on the keyboard , , or . The height gauge will move in the required direction in order to establish contact with the workpiece to be measured.
4. Once the contact is established, it is important to wait for the validation of the software in order to proceed with the displacement of the probe in the bore/axis to be measured.
5. Once the minimum (or maximum) point passed, the software will issue a beep. The probe will retract (displacement defined in the system parameters) and stop.
6. The result is automatically displayed on the screen of the control panel.

The first steps of measuring a bore or axis are the same as the steps described here . The
only difference is the keyboard action selected. Now you have to either activate for axis measurement, or for bore measurement.
1. As soon as the first culmination point has been determined, the probe will automatically move in the direction of the second point in order to be positioned in contact with the opposite part of the element to be measured.
2. Once the contact is established, it is important to wait for the validation of the software in order to proceed with the displacement of the probe in the bore/axis to be measured.
3. Once the minimum (or maximum) point passed, the software will issue a beep. The probe will retract (displacement defined in the system parameters) and stop.

13 ST1 MODE
13.1 Generality
Instruction manual for MH & MH+M
The access to ST1 mode does not require the determination of the probe constant.
This has a direct impact on carrying out a measurement sequence. All measurements regarding the same reference have to be carried out by probing in a direction similar to the one chosen when the active reference has been captured.

Instruction manual for MH & MH+M
The ST1 mode can accept several different references. This means that the measurements stored in the memory may not have been taken in the same direction if they are depending on two different references.
In this example, measurements M2 and M4 are probed in two opposite directions. This is possible as these measurements depend on two distinct references A and B also captured in two opposite probing directions.
This mode is accessible from the main menu by activating the key at any moment.
13.2 Capturing the reference value
In ST1 mode, reference values are always captured with single probing.
This reference value can be defined by a single probe hit ( , ) or by measuring a culmination point ( , , , ). As explained before, the probing direction used when capturing this reference value will determine the probing direction of the following measurements.
Thus, the following process is impossible as the reference is probed down and the measurement up:
Any measurement with inverted probing direction compared to the direction defined when the reference value has been captured, will generate a warning beep. Therefore, no point is stored in the memory.

14 ST2 MODE
14.1 Generality
Each time when entering ST2 mode, it is necessary to calibrate the probe . Once this has been carried out, you can either probe up or down for any measurement sequence.
Examples of a measurement sequence in ST2 mode
This mode is accessible from the main menu by activating the key at any moment.
14.2 Probe calibration

When entering ST2 mode, the probe calibration process starts automatically (for further
The procedure for determining the probe constant is only re-executed if the user leaves the ST2 mode and enters in another mode (ST1 ,
Perpendicularity ). Thus, an intermediate modification of a system parameter (in ) or the use of the integrated calculator does not imply a re-determination of the probe constant.
When entering ST2 mode, once the probe calibration has been performed, the reference values can be captured through single or double probing.
87
Instruction manual for MH & MH+M
Once this reference value has been captured, the measurements can be carried out with single or double probing.
14.4 Single & double probing
The concept of single and double probing has been developed in order to allow the direct measurement of certain elements and quick access to their features. While single probing
enables only height measurements in order to gain some time, double probing is the way to minimise the number of measurement steps and to improve cycle time. Therefore, everything depends on the application.
Note that double probing allows you to position a reference value at levels that would be impossible in ST1 mode:
•
Centre of groove or rib
•
Centre of bore or axis
Other configurations are also possible (example: between two circles) but used less frequently.
As each application is different, it is the responsibility of the user to define the most appropriate measurement steps. In many cases, a similar result can be reached via two measurement sequences. Only their steps are different.
In order to illustrate single and double probing, two different measurement procedures with the same result are shown below. Note that each measurement block corresponds to one step that has to be carried out independently of the others.
88
Instruction manual for MH & MH+M
Measurement process with single probing Measurement process with double probing
The two examples above clearly show that in certain cases, it is better to go for double probing. The first solution requires 3 measurement blocks (and therefore two different measurements and a calculation) to get a result, while the second one only requires one.
It is important not to mix single/double probing and ST1/ST2 concepts.
Here is a summary giving the overview:
ST1 mode •
Single probing only
• Probing in reference’s direction only
ST2 mode •
Single or double probing possible
On motorised MICRO-HITE+M height gauges, the number of probe contacts for measuring an element is intrinsically linked to the activated key on the control panel (for further details,
see this chapter ) or the action run with the rotary control handle (for further details, see this
For example, corresponds to a up single probing, while allows you to start a double probing measurement going up and down.
On the other hand, the manual MICRO-HITE height gauges behave differently. Their ST2

2. The following step is the definition of the measurement reference. In our example, this reference value is only a fixed point used to define the indirect reference.
Once steps 1 and 2 are finished, all measurements will be calculated according to the indirect reference A.
The option can only be selected when the software requires to define a measurement reference. Any modification of the value of the indirect reference will implicate a redetermination of the measurement reference.
For further details, see this chapter .
The MICRO-HITE and MICRO-HITE+M offer the possibility to work with two measurement references called A and B at any moment. You will automatically be asked to define a reference in the following situations:
Mode Description
ST1 When you enter into this mode for the first time
ST2 Following a calibration of the probe
At the same time, it is also possible to force the definition or re-definition of a measurement reference by:
•
pressing the key , which will restart the process of determining the active reference
•
pressing the key or on the control panel during 3 seconds. As a result, the last measurement block in the measurement memory (calculated or measured) is taken into account as active reference value.
A reference can be activated by pressing the key or on the control panel. This is only possible if the reference value has been defined previously. Otherwise, an error beep will warn you that this reference cannot be used for the moment as it has not been defined yet.
It is possible to delete the last measurement block in the memory at any moment via the key . This deletion is independent from the selected block(s) in the measurements list.
The name of a selected measurement block in the history can be edited at any time
Instruction manual for MH & MH+M with the button .
When calculating, it happens that the name of the newly created block is automatically defined according to the previously selected blocks for calcul ation (example “M3-M5”). This name is informative and can also be modified via the editing key.
Below an example of introducing a block name:

It is possible to calculate the distance between two heights (calculated and/or measured) using the key of the control panel. However, it is important to know prior to the measurement which results (measurement blocks of the list) have to be taken into account during the calculation. There are two options for the user.

14.15 Two measurement blocks selection
There are two possibilities to do so:
1. Use the arrows and of your control panel
2. Touch the block directly on the touchscreen
When a calculation involves several measurement blocks, it is important to take into account that the order in which the blocks are selected will have an impact on the final calculation
(on the sign of the result).
The multiselection of blocks is mainly used to calculate a height difference or a middle/average height .
There are two different ways for a multiselection:
1. By quickly clicking two times on the block to be selected directly on the screen.
2. By displacing the focus (blue bar) on the block and pressing the key of the keyboard.
Note that selecting a block will add a (1) or (2) after the number of the block (for example
M3 (1)). This number is crucial, as it directly depends on the order of selection and will play a role in the sign of the result.
If you would like to deselect a block, you can:
•
Quickly click two times on the selected block (touchscreen)
•
Displace the selection on the block and validate the deselection using the key on the keyboard.

16.1 Introduction This mode allows you to measure an angle very easily and in only a few steps. It requires the use of a standard in order to be able to determine the distance X below (the use of an intermediate piece between the standard and the instrument is often required).
This mode is accessible by pressing the key in ST1 or ST2 measurement modes.

4. At this step of the procedure, ΔZ (or Z) has been calculated (for further details, see this
chapter ). It is now necessary to define ΔX (or X), which corresponds to the size of the
standard used. There are two possibilities for the user to do so:
→ Enter the gauge block’s value manually by clicking on . Once the value has been entered and validated, it is necessary to finalise the process ignoring the last steps by pressing (see step No. 6).
102
Instruction manual for MH & MH+M
→ Continue the procedure and measure the standard by capturing point No. 3.
As the standard has been turned by 90° in order to be measured, the software uses an option mentioning the Z-coordinate: . However, this is still the distan
5. Now determine the size of the standard by measuring the last point of the process.
6. The measurement results are displayed on the screen. The angle value is automatically saved in the measurement programme. The values of the secondary results can also be stored in the memory by clicking on .
16.4 Cone angle measurement principle
7. It is possible to restart the process by measuring the first point defining another angle, press
to go back to ST1 mode (respectively ST2 ) or to go back to the main page.
The steps of the procedure to measure the internal or external angle of a cone are almost identical to those detailed previously in the chapter about flat surfaces. The only difference lies in the nature of the points measured on or in the cone. Indeed, instead of measuring points on a flat surface, in this case the heights will be measured as culmination points.

17 CALCULATOR
17.1 Generality
Instruction manual for MH & MH+M
The calculator is a very common object and still indispensable for many different and complex measurements. As it is important to be able to work with the measured values without the need to save them on a device or to write them down on paper, a Calculator mode has been integrated into the MICRO-HITE or MICRO-HITE+M for more ease of use during the measurement process.
This mode is accessible from the main menu by activating the key at any moment.
17.2 Concept The concept of this mode is based on the fact that the user has the possibility either to use it as a standard feature, meaning that the user can manually enter the values that will be used during a calculation or also re-use one or several results of previous measurements (blocks of list).
The mode is presented in the form of a software page split into two distinct parts defined by their function. The zone on the left defines the measurements list. The right zone allows you to enter values and a measurement function.
104
Instruction manual for MH & MH+M
17.3 Use of the measurement blocks
The advantage of this integrated calculator is that the results of previous measurements can be reused for calculation of more complex functions that cannot be defined directly via the control panel.
It is important to know in which way the measurement results can be taken into account in the calculation function. You simply have to
•
quickly double-click on the measurement block and the value will automatically be copied in the bar dedicated to writing the calculation function.
17.4 Changing measurements list
17.5 Customised calculation function
•
Move the selection (blue bar) using the keys , , and then validate your choice using
.
The two measurements’ lists of ST1 and ST2 modes are independent from each other. By default, it is the memory of the last mode that has been activated that will automatically be displayed when entering the Calculator mode.
However, it is possible to go from one memory to the other by clicking on the context-based action key or .
At each change of measurement list, the function defined in the calculator is automatically erased.
The display of the Calculator mode is defined by two lines:
105
Instruction manual for MH & MH+M
The first line corresponds to the function chosen by the user but only includes the labels of the selected blocks. The second line corresponds to the same function but shows the measurement values of the selected blocks.
It is possible to create a customised function block saved it into the measurement list by clicking on the context-based action key (e.g. in our example, the calculation block created will include the function M3+M4).
It is possible to recall a customised function saved in a measurement block by selecting the measurement block and pressing on the context-based action key .

18 PERPENDICULARITY & STRAIGHTNESS MEASUREMENT
18.1 Generality
Apart from the standard measurement ST1 , ST2 , angle measurement and parallelism measurement modes, the MICRO-HITE and MICRO-HITE+M have also been especially designed to allow the user to detect form and orientation errors. In other words, they can also be used to determine perpendicularity and straightness deviations.
This mode is accessible from the main menu by activating the key at any moment.
There are several types of accessories that, together with the MICRO-HITE or MICRO-HITE+M, allow this determination. Below several possible configurations (non-exhaustive list):
+
TESA IG13 All TESA USB 1D probes Standard TESA 1D probe
+
Display Twin-T10
Except for a joint use with the IG13, any other configuration cannot claim to reach other specifications than the ones announced as a mechanical frontal perpendicularity error since the values of the accessories are not compensated. For further information, please contact your local reseller.
107
Instruction manual for MH & MH+M
The perpendicularity mode of the MICRO-HITE or MICRO-HITE+M are only accessible using a
IG13 or any other TESA USB 1D probe.
18.2 Mounting an
IG13
The IG13 probe is an optional accessory that enables measurement of all geometric errors
defined here . This probe is composed of different elements:
4
5
6
No. Description
1 Probe head
2
3
Fixing support
Tightening knob
Probe
Connector
Mounting shaft
The IG13 must always be used with its fixing system (2), which has to be mounted on the mounting shaft (6). The cable of the probe has to be connected to the plug (5).
1. Before starting to remove the probe and its support on a MICRO-HITE, it is highly recommended to use the locking ring in order to avoid that the measuring carriage will be displaced upwards by the internal counterweight of the instrument.
2. Block the measuring carriage.
3. Remove the probe and its support from the mounting pin.
108
Instruction manual for MH & MH+M
4. Mount the IG13 on its pin.
5. Connect the IG13 to the height gauge.
6. Unblock the locking ring. The IG13 is now ready to be used.
18.3 Mounting a
TESA USB probe
When using the MICRO-HITE or MICRO-HITE+M together with a TESA USB probe, it is necessary to use a probe insert holder (TESA reference: 00760222) specifically adapted to the diameter of the accessory.
Before starting to remove the probe and its support on a MICRO-HITE, it is highly recommended to use the locking ring in order to avoid that the measuring carriage will be displaced upwards
109
18.4 Adaptor for
IG13 connection
Instruction manual for MH & MH+M by the internal counterweight of the instrument. For more details, see the previous chapter on mounting the IG13 probe.
Once the measuring carriage has been blocked, the mounting of the probe-holder system can be performed as described on the photo above.
The end of the probe cable must connect directly to one of the USB inputs, behind the panel. It is not necessary to connect the probe to the first USB port. The three ports can be used without any distinction.
If you already had an IG13 before purchasing your MICRO-HITE 2016 or MICRO-HITE+M 2016, it is possible that your accessory cannot be directly connected to the instrument, as the male connector of your IG13 is different from the female connector of your new height gauge.
Therefore, it is necessary to use an adaptor cable (TESA reference: 00760247).
110
Instruction manual for MH & MH+M
18.5 IG13 positioning When you are determining perpendicularity and straightness errors, you can measure in the following directions:
•
Frontal
•
Lateral left
•
Lateral right
18.6 Measurement principle
As a result, the instrument includes the automatic compensation of accuracy errors.
The automatic correction of measured values is only active when the IG13 is connected and positioned in one of the three directions determined above. If this is not adhered to or another accessory is used (for example a lever-type dial test indicator), the automatic correction remains inactive and the perpendicularity deviations can exceed the max. values indicated.
1. If your height gauge does not detect a connected probe when entering the mode
Perpendicularity , a message that asks you to do so will appear. To know how to connect your probe, please refer to the previous chapters.
2. Once the accessory is properly connected to the instrument, if you are using an IG13 probe
(otherwise please go to step No. 4), the software will ask you to initialize it. Note that each change of direction of the IG13 will require a reinitialisation (for further details, see this
111
Instruction manual for MH & MH+M
3. Initialise the IG13 by gently pressing its probe until the detection process validates that the probe is correctly recognised.
4. Once the IG13 is initialized or the 1D probe detected, the instrument is ready to measure.

Instrument ready to measure, MH, IG13
For the further process, illustration images comprising of a IG13 will be used. The steps remain however exactly the same if you want to use a 1D probe.
Instruction manual for MH & MH+M
5. Move the workpiece to be measured to the zone of the probe, so that you are able to position it “with pressure” on the surface to be measured. If possible, maintain enough pressure, so that the probe is positioned in the middle of its measuring range.
6. When using a MICRO-HITE, the measurement can only start once the context-based action
has been selected. For a MICRO-HITE+M, simply activating the probing up or down
options will start the measurement. Note that the rotary control handle can also be used to start the measurement.
7. Once started, the measurement is stopped by a confirmation on the key .
8. The results are automatically displayed on the screen.
18.7 Displacement speed and direction (MH)
Unlike the motorised MICRO-HITE+M, which has a constant displacement speed during the entire measurement process, the displacement speed of the manual MICRO-HITE directly depends on the user via the handwheel used for displacement.
As all measurement points are stored at a given frequency during the measurement, the displacement speed plays a role in the measurement results. With a high speed, the distance between the measurement points will be bigger and less representative of the measured workpiece. The closer the measured points are, the closer the result will be to reality.
Therefore, if the probe displacement is too quick and exceeds a limit defined in the software
(cannot be configured), an informative message will automatically be displayed on the screen.
This message only mentions that the speed is too high and that it is important to reduce the speed for good measurements. However, the capturing will not be stopped.
113
Instruction manual for MH & MH+M
18.8 Zero setting
The graph above is an example of the result obtained by using a IG13. The distance between the red points is not the same, which means that the measurement speed had varied. The smaller this distance is, the more precise the (blue) result curve will be.
In addition, it is important not to change abruptly the direction of the probe displacement during the measurement. In other words, if you start the measurement directing the probe upwards
(respectively downwards), it is important to maintain this direction during the whole measurement and to avoid going back and forth on the surface. This could have a negative impact on the measurement results.
Once initialised, the probe sends its position to the measuring range (displayed on the screen).
Most of the time, this value is not representative for the result to be obtained.
Once positioned with “pressure” on the workpiece, it is important to set this value to zero before the measurement, in order to have a reference value and to be able to easily read the results once they are displayed on the screen.
18.9 Measuring range
It is possible to define a range that represents the distance (from the height where the measurement starts) in which the measurement is defined. Once this distance passed, the measurement will automatically stop.
114
Instruction manual for MH & MH+M
This distance can be set by pressing on the following context-based action: . If a value is inserted, it is displayed on the screen as shown in the above picture (10mm).
18.10 To pause the measurement
The schema above symbolically represents a measurement upwards with the IG13. Once the measurement automatically stopped, the results will be displayed.
In certain situations, or application cases, it is not possible to continually measure a workpiece in order to define the perpendicularity error for example.
This is why a context-based option is visible at the bottom of the screen when the measurement is started. This option allows you to pause the measurement in order to be able to displace the probe from one measurement zone to the other without influencing the results by capturing points you do not want to measure.
18.11 Measurement results
The schema above represents a situation in which the option is necessary. While the measurement is direct in the first zone, the option is required in order to allow the displacement of the IG13 on the upper part of the workpiece without changing the measurement results.
Once the measurement has been confirmed, several characteristics are automatically been displayed on the screen.

19 2D MODE
19.1 Introduction The MICRO-HITE or MICRO-HITE+M is a height gauge that is basically used to measure only when being positioned on a reference plane (granite table) (3) or any other similar surface.
The measures are then performed in one coordinate direction only (2), orientated perpendicularily to the reference plane (1).
Indeed, it is not possible to proceed to measurement of elements directly in two coordinates without going through measuring steps split by a piece rotation in the directions of the wished coordinates.
The 2D mode is directly accessible from the button of the keyboard when being in ST2 mode.
19.2 Concept
The 2D mode is enabled only if a reference has been previously defined in
ST2 mode. If you cannot select the 2D mode, return in ST2 mode pressing
, then define the reference and come back to the menu with again.
The use of the 2D mode implies to go through two steps that will allow then to start the analysis from the received results called “raw data”.
•
Step 1 : Y coordinates measurement
•
Step 2 : Z coordinates measurement
The opposite is also valid as the user has the possibility to switch from one axis to the other.
Even if it is possible to change the reference axis in the middle of the raw data measurement, it is preferable to measure all coordinates of the same axis straight and then change the axis for the second batch of measurement in the other axis.
The first step consists in measuring all Z (or Y) coordinates of axis and bore centres.
117
Instruction manual for MH & MH+M
Then the piece is rotated by a wished angle (in our example the part is rotated by 90°) in order to position the part good enough to measure the second Y (or Z) coordinates.
Once rotated, all same elements have to be measured again in a similar sequence as the one followed previously for Y coordinates measurement.
19.3 Two measurement possibilities
(Y;Z) coordinat es of each element is called “raw data”. It is from these values that calculation will be performed. The analysis is the last step of the process.
For each axis or bore measurement, the user has the possibility to find the element centre height following two processes:
Without looking for the culmination point
On MICRO-HITE+M this way of doing corresponds to the button of the panel keyboard.
This process is the mean to determine quickly the centre coordinate without getting the diameter of the measured element. Indeed, the below graph shows a H coordinate research through measuring option. The probe is probably not centred in the bore. Therefore the
118
Instruction manual for MH & MH+M software will determine the H coordinate using le P3 point but the distance between P1 and
P2 does not correspond to the diameter of the bore.
The software will then display only the measured coordinate in the corresponding block (Z in our case).
Looking for the culmination point
On MICRO-HITE+M, this way of doing corresponds to and button of the panel keyboard.
On the contrary, using one of the methods for checking the culmination point, P1 and P2 are really the maximum and minimum locations of the bore. This is the reason why, as results, H will be given as P3 coordinate as well as the bore diameter, distance between P1 and P2.
19.4 Application examples
In this case, the software displayed not only the measured coordinate but also the element diameter.
119
19.5 Step by step example
Instruction manual for MH & MH+M
In this chapter we will show an example in order to clarify the needed steps to determine and get the right raw data. If you want to have more information about how we can the analyse the data, please refer to the next chapters.
For this example, we will consider that the angle between the two reference surface of our part is perfect, at 90°.
Before starting any measurement in 2D mode, it is important to know the angle between the two supporting surfaces of your part on the granite table.
This angle can be, for instance, determined with the help of an IG13 probe.
For more information, please contact your local representative.
1. From main menu, enter in ST2.
2. Calibrate the probe using the masterpiece delivered with the instrument.
3. Once the probe calibrated you will enter automatically in ST2 mode.
120
Instruction manual for MH & MH+M
4. Take the reference on the table on which the part to be measured will be placed. Please note that if the reference is not measured, you will not have the possibility to enter the 2D mode.
5. Press button from panel keyboard.
6. Select 2D mode. The software shows now the page dedicated to raw data measurement.
7. Position the piece on the table so that the probe can access all elements you want to be measured.
121
Instruction manual for MH & MH+M
8. Measure each bore following the official processes described before in this document
(up/down or with culmination points).
9. Rotate the part in order to position it in an optimal way for the measurement of the second coordinates (in our example it is 90°).
122
10. Press , insert the rotation angle (90° in our example) and confirm.
Instruction manual for MH & MH+M
11. Start the measurement of the second coordinates in a similar sequence as the one followed to measure Z coordinates.
12. Raw data are now measured
It is always possible to continue to add raw data going from a coordinate to another via the and actions.
If raw data measurement process is over, it is possible to go to the values display and analysis page using .

3 Graph that represents the coordinate system as well as all calculated and measured elements
Once raw data are known, the first step consists in setting a datum. For this explanation we will continue with our previous example.
1. Select one of the raw data blocks (C1 for instance). For this, you can either click on the wanted block from the touch screen or use the keyboard arrows buttons.
Note that the selected block has a (1) nearby its name and that the corresponding circle has become blue in the graph.
Selecting a bloc (blue rectangle) implies the corresponding element becomes blue in the graph.
The available options (linked to the selected blocks) are displayed in the bottom screen bar.
In our example, when a unique point or a circle is being selected, only this option is available.
It is the option that allows to set a point or the centre of a circle as reference/origin.
2. Press .
124
All coordinates have been modified according to the new origin that we can see in the current datum status bar. C1 is now the new origin.
Instruction manual for MH & MH+M
We consider now that we want to define the line going through C1 and C2 as Y axis reference.
3. Select C1 and C2 blocks.
4. Press .
19.8 Where is the current datum?
A C4 line is automatically created in the list and set as Y axis reference (visible as well in the current datum status bar).
If you cannot remember where the current datum is, you can simply look at the graph on the right side of the screen and find where the icon is.
19.9 Change the coordinate system

The selection sequence has an impact on the result.
In order to calculate the angle between two lines it is mandatory to select two blocks representing lines and confirm the action with .
The selection sequence has an impact on the result.
Sometimes it is important to be able to obtain the angle that a line forms with one of the axes of the current datum. Therefore you can just create the desired line (see these
chapters: line by two points , bestfit line ) in the measurement history. The created block will
always automatically contain the angle that the line forms with the Z axis.
If you want to get the angle that the line forms with the Y axis when running a program, you just have to exit the 2D mode and create a customised function block containing: 90 ° angle with Z-axis.

19.27 How to integrate a result from the
2D mode into a measurement program?
Instruction manual for MH & MH+M
As you have seen earlier in this chapter, the 2D mode can exclusively be accessed via the
ST2 mode. That means, that the 2D mode is included in the ST2 mode, as well as in the Angle or Min, Max, Delta mode.
Therefore, in order to be able to re-execute a 2D calculation sequence later on another piece to be measured, one or more results from the 2D mode must be saved in the history of the
ST2 mode.
The measurement blocks of the ST2 mode are generally called M1, M2, M3, M4, ... (M for
"measure" in English). The measurement blocks of the 2D mode are generally called C1, C2,
C3, ... (C for "circle" in English). This is why you will be able to store a 2D result in the ST2 mode memory by pressing the context-based action . A block C of the memory of the 2D mode then becomes an M block in the ST2 mode memory.
Below is an example of a program creation containing results from the 2D mode.
1. Calibrate the probe to enter ST2 mode
(P1)
2. Capturing the reference (R2)
3. Measurement of any point (M3)
4. Measurement of any other point (M4)
5. Switching from ST2 mode to 2D mode
6. Measurement of the Z coordinates of two circles
7. Rotate the part by a given angle
8. Measurement of the Y coordinates of the two circles
9. C1 and C2 are raw data ready to be used
10.Calculation of the distance between these two circles (C3)
11. C3 is sent in the memory of ST2 and becomes M5
12. Measurement of any point (M6)
13. Measurement of any other point (M7) and continuation of the program
14. Saving the program on USB key
The screen shots below succinctly describe the previously explained process. We will consider that the basic principles of the ST2 mode (calibration of the probe, ...) and 2D
(measurement of raw data, ..) are known.
132
From the ST2 mode where there are already four memory blocks (probe calibration, capturing the reference and any two measurements), switch to the 2D mode via the secondary function menu . Once in the 2D mode measure two circles using the normal procedure explained in this chapter.
Instruction manual for MH & MH+M
Now that the two circles are measured, calculate the distance between their two centres.
A new C3 block is created in the memory. Now you have to transfer it to the ST2 mode memory by pressing the button. At this moment a beep should sound.
A new M5 block is now created in the ST2 mode memory. This block represents the distance between the two circles measured in the 2D mode. The user can continue to feed ST2 mode memory by continuing the measurements or saving the program.
When the software arrives at the M5 block during the execution of this program, it will automatically enter the 2D mode and ask the operator to measure the two circles he needs to set the M5 distance.
133
20 ZZ MODE
20.1 Generality
Instruction manual for MH & MH+M
ZZ mode (or continued display) is often selected when a measurement requires a lower probing force than that proposed by the column in a standard configuration. This is the reason why this mode is mainly used with an external measurement unit (for example a lever-type indicator).
This mode is accessible from the main menu by pressing the key at any moment.
20.2 Operating principle
This mode is called continued display because the value displayed on the screen is updated at any time according to the position of the carriage for displacement on the glass scale of the instrument.
When using this mode, it is firstly important to lock the double carriage by tightening the screw on the front of the instrument.
134
The continued display can be reset at any time by pressing the context-based action .
It is also possible to save an instant value in the measurement list by pressing the button on the control panel.
Instruction manual for MH & MH+M
It is not possible to save a program from the ZZ mode. It is not possible to use the calculator starting from the ZZ mode values.
You can quickly calculate differences or averages by pressing the or keys on the control panel.

21 DATA MANAGEMENT
21.1 Generality Your control panel offers the possibility to manage measurement data by sending it to several different peripherals. Each one of these processes is independent from the others.
Therefore, each one of the possibilities can be enabled and used at the same time as the others. All combinations are possible. You could for example store your data on a USB key and, at the same time as sending results to a computer via the TLC connector.
It is not possible to connect the control panel directly to the local network of a company. The only possible solution is to send data to a computer, which is itself connected to the intranet.
Data management parameters are accessible via the key of the main page that you can access at any time by pressing the key of your control panel.

Instruction manual for MH & MH+M
M17 97.193 mm
With the MICRO-HITE or MICRO-HITE+M height gauge, reports in *.pdf format can be created on the USB key connected to its panel. The creation can be done:
•
automatically after the execution of a measurement programme
•
manually when the user selects the action to create the *.pdf file in the context-based action bar
The user can define the process for the report management from the system options menu.
Header
The measurement report has a header containing the following information:
What
Operator's name
Company name
Part name
Batch name
Date
Time
Company logo
Note
Is editable in the system options menu
Is editable in the system options menu
The program name is used as the part name
Is editable in the system options menu
-
-
The file named company_logo.jpg
stored in the root folder of the
USB stick is taken into account.
The company logo is not compulsory. If the panel does not find any logo when creating the document, the area dedicated to the header will be automatically adjusted.
Image of the part
The image of the part can be inserted at the beginning of a measurement report. As for the company logo in the header, the software will check when creating the document, if a file corresponding to the executed program exists at the root of the USB key. If this is the case, the image will be taken into account, otherwise the document will be adjusted accordingly.
Please note that the system is flexible. Indeed, it is possible to have several programs stored on the USB key and for each program a different image to display on the measurement report.
An image must bear the same name as the program to be taken into account when creating a *.pdf measurement report at the end of the sequence execution. Here are some examples:
Name of the program Name of the image stored in the root folder of the
USB key

21.8 Annotate a measurement program
When running a measurement program created by a third person, it is often convenient to be able to rely on explanations or notes made by this person. To do so, it is possible to create on the USB key, a document in *.pdf format describing the program currently stored on the panel and giving the possibility to annotate each of the measurement blocks of that program.
It is possible to generate this document on a USB key from the program management screen.
Simply press the context-based action corresponding to the *.pdf document to generate the document on the USB key.
Sample annotation document:

21.9 Screenshot In order to simplify the creation of personalised procedures, sharing knowledge and training employees, it is possible to take a screenshot at any time.
It is necessary to connect a USB key at the rear of the control panel and to maintain the key
pressed for approximately 3 seconds until a validation beep is generated.
It is possible that the control panel does not detect the USB key if the time between the connection of the key to the panel and the screenshot is too short.
The panel needs a few seconds in order to recognise that an USB key has been connected.

Instruction manual for MH & MH+M
22 PROGRAM MANAGEMENT
22.1 Introduction Because beyond the simple measurement of a unique part there is often the need to control a batch of pieces that could be either small or big, TESA developed a learning mode that gives the mean to manage in a simple way measuring sequences. Once the program has been run, general information of the piece status is automatically displayed on the panel screen.
22.2 Program creation The programming principle by learning means the creation of a measuring sequence on an arbitrary piece (from a batch or not). These measuring sequences can be realised either from ST1 or ST2 mode.
The part that is used to create the measuring sequence is not to be considered as reference part. It is only the mean to define the steps of the sequence by measuring feature after feature on it.
In fact, each block from the measurements’ list corresponds to a step of the measuring sequence that can be executed later. This means that all measurements’ list corresponds to a potential measuring sequence.
For instance, this memory of 5 blocks defines a 5 steps measuring sequence.
22.3 Insert tolerances The tolerance management implies that measurement blocks are in memory. Without blocks, it is not possible to insert tolerances.
Once the sequence has been done in ST1/ST2, press button from panel keyboard.
143
144
Instruction manual for MH & MH+M
You have now the possibility to choose the option concerning programs management.
The displayed page corresponds to a blocks’ list equivalent to the one in memory. With this sequence global view it is now possible to proceed to the tolerancing for all dimensions to be controlled.
Inserting a value for this is possible :
•
Clicking on the wished square (touch-screen) and enter the value using the panel keyboard
•
Double clicking (touch-screen) on the wished square and using the numerical keyboard displayed on the screen
•
Selecting the wished square with the panel keyboard arrows and confirming with .
Instruction manual for MH & MH+M
22.4 Tolerancing with
ISO table
In order to use the ISO table to set tolerances it is mandatory to be located in the page dedicated to tolerances insertion.
Once a nominal value for a diameter has been confirmed, the button is automatically displayed at the bottom of the screen. It allows accessing the following table.
22.5 To save a
sequence
It mean snow only to select the wished tolerance and confirm it in order to load automatically the values for the given characteristic.
Once your sequence has been correctly done you can save it into your USB stick. For this, press button from the panel keyboard then select programs management option.
145
Instruction manual for MH & MH+M
This page will be displayed. It is now possible to insert tolerances (but not mandatory) then to save the sequence pressing .the next step is to enter the program name and confirm it to end the process and save the data in the USB stick.
A sequence that has been done in ST1 mode will be saved with *.st1 format. It is the same for ST2. For this case the *.st2 format will be used.
On the top right side of the window, the number of still available characters as well as the number of total characters are displayed.
22.6 Sequence loading Loading a measurement sequence from USB stick does not imply that i twill be automatically run. Indeed, the loading only recalls the sequence and places it in corresponding memory
(ST1 or ST2).
The blocks from the memory are automatically overwritten when loading a program from the USB stick. It is not possible to get these blocks back.
A sequence can be recalled whenever from ST1 or ST2 mode pressing from control panel then selecting the programs management option.
Prior to load a ST 2 sequence from your USB stick, it is not mandatory to have your probe being calibrated. You can directly access the program management options from the probe calibration page pressing button.
146
Instruction manual for MH & MH+M
Once this page is being displayed, press , select the wanted program from the list and confirm your selection.
22.7 To run a
sequence
When recalling a program, you will have access to a programs’ list corresponding to the sequences saved into your USB stick. If you want to recall a program from ST1 mode, the list will only show programs with
*.st1 format. It is the same recalling a *.st2 sequence from ST2 mode.
Once a sequence has been loaded in memory, it can be either modified or run in loop.
Running a sequence requires blocks in memory. These blocks can either come from a program that would have been loaded from your USB stick or simply from measurements performed without any prior saving.
Once you are sure your program in memory is the one you want, press button from panel keyboard and select the programs management option.
Insert tolerances if needed and start the process pressing .
147
Instruction manual for MH & MH+M
When running a sequence a icon is displayed on the left of the screen. It represents the current measurement step in the program and inform the user of the block that is currently run.
When using a MICRO-HITE+M, a time countdown is also displayed (the time is editable from system options menu). It is the mean to know the remaining time before the next probe displacement and let the user avoid any crash of the probe with the part to be measured.
22.8 Pause a
sequence run
When a measurement sequence has been started, it can be paused at any time by pressing the context-based action .
148
Instruction manual for MH & MH+M
Once the sequence has been paused, it can be continued by pressing the context-based action .
22.9 Remeasure a
block
22.10 Waiting time
(timer)
When running a measurement sequence it is not uncommon to wish to measure again the dimension that has just been measured. This is possible by pressing on the contextbased action. The light blue cursor will then reposition on the previous block to allow its re-measurement.
It is possible to go several blocks back by repeatedly pressing the context-based action .
When running a measurement sequence with a motorized MICRO-HITE+M, it is important to give the operator time to position the probe, so that it does not strike the workpiece when moving to the next measurement zone.
To do so, the operator can enter the desired number of seconds before moving the key in the system options menu.
This timer will be used before moving to a measurement zone or before any measurement.
If the user inserts the value 0 as a timer value, he must manually confirm the movement to the next block in the entire measurement sequence by pressing the action.
Below, you can find a sample sequence to understand the sequence recall moments during which the countdown will be used.
149
Instruction manual for MH & MH+M
1
The probe is inserted into the groove manually by moving the part or the instrument
2
A probe hit has the effect of starting a countdown until the probe will be moved to the next measurement zone.
3
During the countdown, the operator has time to withdraw the probe from the part to avoid any subsequent collision.
4
The countdown is finished, the probe automatically moves to the next measurement zone
5
The probe has stabilised at a height close to the measurement, a new countdown was started
6
During the countdown, the user can position the probe appropriately over the area to be measured
22.11 Results
7
The probe is now in a good position, the countdown is not finished
8
Once the countdown is at
0, the probe goes down to measure a point
If the distance between two measurement zones (two measurement points) is small enough, only one countdown will be used in order to save time.
Once you have run a sequence and reached the end of it, a result page is automatically displayed.

22.13 Calibration block and execution in a loop
22.14 Reference block and execution in a loop
You’ll find on the page :
•
Part status
- Good
- Not good
- Program end (if the sequence does not include any tolerances)
•
The number of
- Measurements in black (measurements whose tolerances have not been entered)
- Values in tolerances in green
- Values to be reworked in yellow
- Values out of tolerances in red
•
Run time
•
Run number
•
Part name (corresponding to program name)
•
Batch name
•
Operator name
It is possible to filter the result values by status. To do so, press one of the button. It will display only the corresponding values having the same status (all good, all bad or all having to be reworked).
Once the end of a sequence run is reached, the global results page is displayed. You can either re-run the same sequence from this page using option or exit the process with
A sequence that has been done from ST2 mode will, most of the time, include a probe calibration block as first block. When running a sequence having such block as first one (if there’s no other probe calibration block in the same sequence) running the sequence for the second time will imply that the calibration block won’t be taken into account.
If a measurement sequence takes only one reference (a single reference block) into account during its execution, the software will offer you two ways to manage it:
•
Measuring the reference at each run of the sequence
•
Measuring the reference only at the first sequence run. This reference is kept in memory for future executions (under the condition of not leaving the sequence execution mode).

23 CONTROL AND UPDATES
23.1 Generality As a user, you have the possibility to access certain options that enable a quick control of analysis of your system.
The control options are available in the service menu via the context-based action available on the main page of the software that you can access at any time by pressing the key of your control panel.
23.2 System information
23.3 Control of the system
The first tab of the mode gives you an overview of the configuration of your height gauge.
You can get the configuration information of your height gauge by pressing the button .
A text file that represents the current configuration will be created on your USB key. This configuration can be loaded onto the panel later from the USB key via the button .
When the system options have to be modified according to certain types of applications, it is an advantage to be able to recall a configuration previously stored on a USB key, so that you do not have to manually modify the parameters.
153
23.4 Sensor control
Instruction manual for MH & MH+M
This page of the software enables the visualisation of certain crucial parameters of the system in order to quickly determine the status of the instrument.
23.5 Reference mark control
In order to verify the sensor and its positioning regarding the measurement scale, make sure to activate the option “Lissajous” on the right side of the screen. You should then see a circle appear on the screen, as shown in the above picture. In order to control the sensor of your instrument, you only have to move your probe slowly up or down (avoid moving to the end stop), which will lead to the display of green points on the screen. A sensor has been correctly configured when you see a centred circle appearing.
On this page, the option “reference control” has to be activated first. Then slowly move the probe up or down. It is the same principle as the initialisation of the height gauge after turning on the instrument. The encoder has to pass in front of the control mark defined on the scale
(at a height of approximately 15 cm from the base). If the mark is detected, a beep is generated and a green point is displayed on the screen.
23.6 Software update For the following procedure it is supposed that you already have the file that corresponds to the software version that you would like to load onto your instrument. If you do not have this file, please contact your local reseller.
1. Press the key in order to go to the main page of the software.
154
