2.1
INSTALLATION OF THE SOFTWARE LEVELSOFT PRO
BASIC INFORMATION REGARDING THE SETUP
For using the software LEVELSOFT PRO, MT-SOFT or LabEXCEL WyBus a licence is required. At first a free
of charge test licence for a period of 15 days can be installed. The licence key required can be applied for
through the Internet. For unlimited use a licence must be purchased through your local WYLER partner.
Recommended is a validation with a USB dongle. This is a hardware licence key integrated in a USB key. A
main advantage of the activation with a dongle key is that you can install the software on different computers
and, just connecting the dongle key, you can measure with each of these computers. Without the dongle
connected you can still view or print completed measurements or you can prepare a next measurement or
template.
2.2
The use of LEVELSOFT PRO, MT-SOFT or LabEXCEL WyBus for testing purposes
You have the opportunity to test the software LEVELSOFT PRO, MT-SOFT or LabEXCEL WyBus extensively
as a fully licensed version during a period of 15 days. During or after expiry of this testing period you have
the possibility to buy a full user license. The testing period expired, you can still use the software as a viewer
version (no measurements possible, only viewing and printing of measuring results)
2.3
Using LEVELSOFT PRO, MT-SOFT or LabEXCEL WyBus with a
timely unlimited LICENCE
In this case it is necessary to purchase an official software license through your local WYLER distribution partner
within 15 days. WYLER SWITZERLAND will then validate your licence thus enabling you to use the software
LEVELSOFT PRO, MT-SOFT resp. LabEXCEL WyBus without limitation.
In case you would like to use the software on various computers or Laptops we recommend the application of a
USB dongle key (validation of the licence through a hardware key).
Further information on the installation and the licensing of the software can be found in the separate manual
"Installation of the software LEVELSOFT PRO and MT-SOFT"

GENERAL INFORMATION ABOUT MEASURING
Before you start using the software LEVELSOFT PRO a few but important facts must be considered in order to
come up with satisfactory results
3.1
MEASURING STRATEGY



3.2
Touch the instruments only at the
handle (Temperature!!!)
Measuring from left to right and from
close to far.
Cable in measuring direction
VERIFICATION OF THE SYSTEM









Install and power up the instruments and interface to PC according to the manual
Start the software LEVELSOFT PRO / "Measuring pattern new/change"
Enter Object "Line" /Step length longitudinal 100 mm / Number of measurements: 20
Way of measuring, enter "1 Instrument" and <START MEASUREMENT> / [F11]
Instrument is being initialised <CONFIRM> [F1] or [Shift] + [F1]
Place a piece of newspaper (ca. 10 to 20 µm) under the right side of the measuring base.
Without moving the electronic level read 10 values.
Move newspaper to the left side.
Read the remaining 10 values without moving the instrument.
The result should look similar to fig. 1
Fig. 1
Page 12 of 197 pages
Repeat the same measurements without placing any paper below the instrument's base and without moving the
instrument, which means the instrument remains flat at the same spot. The following could result:
Possible results
Interpretation of the results
Theoretically a straight line and a maximum error of "0" should be the result. This is however impossible due to
unavoidable vibrations (movements of the object to be measured) and therefore changes in the measuring
values on the electronic level. To obtain assertive measuring results the following conditions must be fulfilled:
For extremely precise measurements the maximum error must be less than 0.2 µm and a line character as
shown in "A" or "B" must be obtained.
For medium accuracy of measurements the maximum error must be less than 0.5 µm and a line character as
shown in "A" or "B" must be obtained. Such results can show up due to vibrations, these are random errors.
Line characteristics as per "C" or "D" must be avoided, as these are indication of temperature drift.
Possible causes
 Difference in temperature between the measuring base and the object.
 The whole system may not be at operating temperature or there are temperature differences within the
object to be measured
(Warm-up time for the electronic unit for precise measurements is 15 min.
The adjustment of equal temperature within a measuring objects is depending on size and material and
may need up to several hours.
Attention:
If a measurement is continued when line characteristic "C" or "D" are shown a time depending measuring
error will show up. When the measuring task is time consuming the error will be quite large.
When measurement takes place after receiving curves similar to "A" or "B", even, when the errors are quite
large, the displayed error must be added to the measuring uncertainty. These errors do not change over the
period of time during the measurement. The errors may be influenced by other reasons, such as vibrations.
Page 13 of 197 pages
3.3
CHOICE OF MEASURING BASE
As far as possible for flatness measurements no instrument with prismatic base should be used (except as
reference instrument). This is especially important for surface measuring!
Because the contact surfaces of longitudinal, respectively transversal measurements do not or not sufficiently
overlap, errors can occur.
Also, scraped bases tend to collect dirt because the scraping pockets run out shallowly allowing dust particles to
enter easily between the two surfaces.
The hardened steel measuring bases with knife-edged type, approx. 1 mm broad dust grooves under 45
deg. angle to the measuring direction, have proven especially suitable for measuring on surface plates of
Diabas.
The following table gives an insight into dimensions and application ranges:

Good results are also obtained for measurements on scraped or ground guide way-surfaces with measuring
bases made of granite (Diabas).
Advantages:
Even if the granite bases are damaged no scratches on the work piece surface will occur.
The new developed adjustable measuring bases WYLER is an excellent alternative for precise measurement
(see 5.6.3.2. The flexible base of WYLER). The users will be excited by the easy handling and the multiple
options available. This base is conceptually adopted from the standardised 3-point-supported measuring bases,
which also makes the use of the U-Jack-method a lot easier.
Particularly in combination with the latest version of our software LEVELSOFT PRO this measuring base is a
convincing enhancement. This software allows the automatic calculation and proposal of a suitable measuring
layout in an easy way, taking in account the high variety of possible step lengths provided by the Flexbase.
Another possibility is the use of an instrument with "screw-on" measuring base (Instrument's base length 150
mm) for mounting of larger bases (200 to 500 mm) which are built accordingly sturdy. If the screw-on type is
used with short measuring bases, problems will occur unless the construction is very rigid. Rigid bases tend, due
to the resulting weight, to deform the object to be measured (elasticity). This again results in measuring errors.
Measuring bases with length of 200, 250 and 500 mm can be supplied by WYLER in Diabas as screw-on type.
These are especially suitable for large tooling machines (Straightness and flatness measurement on guide-ways
and tables).
Examples of incorrectly designed bases:
Absolutely flat base
Error:
No clearly defined contact points.
Full surface contact;
Tendency to wobble on uneven work piece
surface, >> resulting in large measuring error.
Measuring surfaces not covering the same surface area
Error:
measuring errors by line- and
flatness-measurements

INFLUENCE DUE TO TEMPERATURE DIFFERENCES
Temperature difference within the work-piece or between the work-piece and the measuring base have a great
influence on the accuracy of the measuring results. The following chapter will deal with some of these coherent
problems.
Influence of temperature differences between the measuring base and the object to be measured
A temperature difference between the measuring base and the object to be measured will cause a heat flow.
The amount of such a heat flow is depending on the area of contact, the difference in temperature, the materials
of base and object as well as on the base length and the cross section of the measuring base.
In the base a temperature lamination will occur which will bend and warp the base because of material
expansion. This will result in constantly changing the area of contact, which on the other side again will change
the flow of heat. Consequently the measuring base is constantly in motion until temperature equivalence is
achieved. These partially brisk motions can be observed by the continuously changing of the instrument's
display value.
The temperature dependant volume changes of the base itself are also visible in the instrument's display value.
Important:
 Before conduction of a precision measurement the temperature of the instrument and the object must be
checked!
 The time for temperature acclimatization of the instrument's base is depending on the temperature
difference and the material used and will be between ½ and 2 hours.
Influence of temperature differences within the measuring object
The influence of the temperature difference within a measuring object can be demonstrated with the formula
applied for calculating the deviation from flatness of a Diabas granite surface plate. The formula is valid for
stable conditions only and deals with the difference of temperature between the bottom side of the plate and the
topside of the plate.

DIFFERENTIAL MEASUREMENT
Measurements conducted with the differential method allow the compensation of slight changes of an object
orientation during the measurement and the compensation of low frequency vibrations.
These compensations are only satisfactory if the measuring object is of rigid design and the supports are of the
three-point type. Also the surface on which the reference instrument is placed must be a solid part of the object
to be measured and of good flatness so that the reference instrument is not wobbling. If these conditions are not
fulfilled the planned compensation cannot be achieved.
Attention
Long machine beds with several bearing points have the tendency of following the shape of the
foundation, this will also give false compensation readings. By this the reference instrument placed on
the machine bed will supply incorrect values. In these cases it is not recommended to apply
differential measuring method.
3.6
MEASURING ERRORS
Possible causes of measuring errors, respectively closure errors of surface flatness measurements or poor
repetition when measuring straight lines are:
 Temperature difference between measuring base and measuring object.
 Tilting of the object to be measured and/or vibrations during the measuring process.
 Careless measurement
 Dirt
 actuating the remote trigger before the instrument's read-out was stable
 insufficient overlapping of the measuring steps during the measurement
 careless positioning of the measuring instrument
 warped, worn or damaged measuring base
 uneven, short waved surface, bumps and burrs which cannot be covered accurately by the
measuring base or result in wobbling of the measuring instrument.

3.7
MEASUREMENT / LAYOUT OF MEASURING PATTERN
The object to be measured must be adjusted horizontally in both directions (longitudinal and transversal) as well
as possible (within approx. 50 µm/m). If not done so, measuring errors may occur if the measuring instrument is
not placed exactly in line with the measuring direction.
The object must now be divided in the measuring step length. The step length has to be such that an equal
dimension of overlapping of the base length with each step is possible.
The best possible step length when using a 150 mm base is 126 mm.
As a guideline it should be noted that if the surface is of bad quality (rough, buckling) then the step length should
be as close as possible to the optimal length (in this case 126 mm).
In addition it is important to make sure that the base as a whole comes to lay on the surface when placed in the
measuring position.
The grid is to be marked on the surface plate with a pencil that does not apply a thick layer.
Example:


Object to be measured:
Measuring instruments:
Surface plate 1200 x 800 mm
BlueLEVEL, BlueLEVEL BASIC, Minilevel or Leveltronic,
horizontal model, Base length 200 mm
Optimal step length would be 170 mm
In our example the calculation was based on the border zone of 30 mm each side. The remaining distance is
divided by the optimal step length, and then the figure set to either the next higher or lower round figure. The
originally defined remaining distance must now be divided by the new fixed number of steps whereas the newly
calculated figure is the step length to chose.
1200 mm - (2 x 30 mm) = 1140 mm
1140 mm : 170 mm = 6.7 Steps
=> 7 Steps; 1140 mm : 7 = 162.8 mm Step length
=> 6 Steps; 1140 mm : 6 = 190.0 mm Step length
Chosen step length 6 x 190 mm and on each side 30 mm border zone
The same method is to be applied for the other direction with a length of 800 mm
Chosen step length 4 x 185 mm and on each side 30mm border zone
On the side of the base the step length may be marked. Also the middle of the base may be marked at the front
and at the end. By doing so it is assured that the measuring instrument is always placed correctly at the spot
required.

METHODS OF ALIGNMENT
In the WYLER LEVELSOFT 2000 the following methods of aligning the measuring objects are possible:



Alignment according to the method “Endpoints”
Alignment according to the method “ISO 1101”
Alignment according to the method “linear Regression”
The different methods are described next and a number of graphics are used for better understanding. The
same applies to the following measuring objects:




Lines / Lines with Twist
Parallels / Parallels with Twist
Surfaces (WYLER Grid always ISO 1101)
90 deg. Angles (Squareness)
By aligning surfaces flat surfaces instead of straight lines are applied.
Procedure of the measurement:
1. All the measuring parameters like e.g. step length, number of measurements, reading method, etc.
are entered.
2. At the end of the measurement the result may be viewed using Menu point 2 “Display Profile”.
The object is aligned as pre-set in Menu point 9 “Alignment method”
3. In menu points 7/8/9 "Alignment according to …" the required alignment method may be selected
Methods for aligning measuring objects, Overview:
a) Alignment according to the method Endpoints
In this method the first and the last measured point are connected by a straight line. The whole figure is now
turned horizontally. The connecting line is moved parallel to the highest and the lowest point of the object. The
vertical distance between the two lines is the maximum error calculated according the method “Endpoints”.
Page 18 of 197 pages
b) Alignment according to the method ISO 1101
In the method ISO1101 two parallel lines are aligned in such away that the distance between them is the least
possible.
The vertical distance between the two lines is the smallest possible error according the method “ISO 1101”
c) Alignment according to the method linear Regression
Using the method “linear regression” a straight line is calculated out of a number of measuring points according
to the method least square.
The so calculated line is moved parallel to the highest and the lowest point of the object. The vertical distance
between the two lines is the maximum error calculated according the method “Linear regression”.
3.9
REMARKS CONCERNING THE “LIMIT OF VARIATION”
Every measured value is computed out of series of individual values. The limit of variation is acting like a filter
using only these values, which are within the set limit of variation.
During a measurement under true practical conditions a number of vibrations may be influencing the
measurement in a way that the limit of variation needs to be adjusted. In most of the cases where such
periodical vibrations are present this is a very efficient way to receive good measuring results because it will
prevent relying on one individual measurement at a crucial time.
Under such measuring conditions it is recommended to start with a limit of variation of 5 µm/m. In case a series
of measured values are rejected the system will repeat the measurement several times.
Page 19 of 197 pages
After several unsuccessful
trials the following windows
appear:
The following options are available:
1 => REPEAT MEASUREMENT
This will start a new sequence of trials to enter a series of sample
values with a variation conforming to the set limit.
Use this option whenever an occasional rejection occurs during
measurement.
2 => ADJUST LIMIT OF
VARIATION
Allow a higher variation to be accepted.
NOTE: The system will offer a suitable value, which may be accepted
by using the space bar. Any value, greater than the one presently
set, may be entered by keyboard.
This option should be taken after frequent rejection has occurred.
3 => ACCEPT MEASUREMENT
Accept the series of values read despite the fact that the variation
exceeds the limit set. When measuring in difficult environment, the
limit of variation should be set close to the variation of the measuring
values.
Remarks:
When the “Limit of variation” will be changed during a measurement
the setting is valid for the measurement in process. The new value
will remain set until changed in the menu “Measuring parameters”
"3 = > LIMIT of Variation“ or until the software will be started from
new.

3.10
REMARKS CONCERNING THE “SURVEILLANCE OF DRIFT”
IMPORTANT:
The surveillance of drift should only be used by experienced users and measuring under extreme surrounding
conditions (e.g. great temperature changes during the measurement).
Various conditions like temperature changes or unstable supports during the measurement may have an
influence on the instrument's absolute zero setting. With the activated "drift surveillance" a possibility is
established to examine the drift condition.
When a measurement is taken with drift surveillance <ON>, the action to be taken will be called by the menu.
For the correct procedure it is important to mark the measuring spots on which the drift condition of the
measurement will be examined. The drift examination has always to be done with the instruments placed in the
same direction as the flatness measurement is done. Therefore a place for every measuring direction must be
available.
The drift examination is always relevant for the upcoming line measurement. It is therefore important to chose
the correct moment for the examination, e.g. after the finishing of a line or at least after finishing the
measurement of all the longitudinal and before changing to the transversal lines.
IMPORTANT:
The surveillance of drift is only available for the measuring objects "WYLER Grid" and "Rectangle".
The instruments must be placed in the same direction as they are for the measurement.
If the differential measuring mode is applied, never change the position of the reference instrument while
measuring a set of lines following the same direction.
During the definition of the measurement in point "Measuring pattern" (see picture below) the "Surveillance of
drift“ must be activated [F7]
Page 21 of 197 pages
By clicking to <Surveillance of drift> [F7] the surveillance of drift can be activated or deactivated.
If the surveillance of drift is confirmed with <YES> / [F1] the respective parameters for “Limit of drift admissible”
may now be entered and the measurement can be started.
Now the measuring instrument must be set at the predefined place. When measuring a surface the instrument is
to be placed in the measuring direction of the next measurement. If this next measurement is for a line in
another direction the instrument must be placed accordingly! In case of a surface measurement the drift check
must be performed after the last measurement in longitudinal direction, on the spot of the first measurement in
crosswise direction.
Page 22 of 197 pages
Before starting the measurement the instruments must be initialised. Follow the statements on the monitor
After initialising of the instruments the following display appears:
IMPORTANT:
The reference instrument must not be touched during the measurement!!!
At every drift examination two measurements must be taken at the same spot. The corresponding result is
displayed in the menu.
Page 23 of 197 pages
At the beginning of a measurement of every new line the drift control must be made according to the above
described procedure.
The value of each drift measurement will be stored and compared with the previous one. If the value is within the
pre-set tolerance, the measurement task will be continued and all the upcoming measuring results will be
corrected by the measured drift value.
If the tolerance is not reached,
the following remark will appear:
The following options are
possible:
1. Retake measurement of
drift
2. Change limitation of drift
and continue the
measurement
3. Accept measured drift
and continue the
measurement.
3.11
PAUSE
In order to avoid unintentional operation the control panels of the BlueMETER resp. the LEVELMETER 2000 are
blocked during the measuring process. For very specific measuring tasks this blocking can be suspended by
activating the key pause [F1]. During the pause no measurement can be taken. After pressing the key pause
[F1] again the instruments will be re-initialised, the control panel will be blocked and the measurement can be
continued.

4.7.19.3
Way of measuring
IMPORTANT:
For using the software LEVELSOFT PRO the measuring instruments must be updated to the latest firmware
version. The measuring instruments of the NT series must be tagged with a serial number.
Normally the software LEVELSOFT PRO will recognise the interface connected provided that the latter is a
WYLER product.
Basically there are the following options of interfaces:
I. The interface connected is a BlueMETER with or without wireless transmission module
II. The interface connected is a LEVELMETER 2000
III. The interface connected is a LEVELMETER LIGHT
IV. The interface connected is a LEVELADAPTER 2000
Procedure in case I)
The interface connected is a BlueMETER with of without
wireless transmission module
Three options are possible:
 Instrument [A]
 Instrument [A - B]
 Console input
for measurements with one instrument
for measurements with two instruments (differential measurement)
for manual input of the values by console
The instruments having been used for the last measurement are proposed again and, provided these are
connected through the same interface and ready for use, the measurement can be performed with these
instruments.
Page 49 of 197 pages
Next it must be defined whether

measuring with one instrument

measurement with two instruments (differential measurement)

manual input of the values by console
is selected
Chose the required mode by clicking the correct icon or use the correct key. Using [SPACE] accepts the existing
set-up.
After entering all the required data the measurement can be started.
IMPORTANT for console input:
When using the console input mode it is important to make the following settings
 The sensitivity of the instrument must be set to 1µm/m and the measured values must be
entered in µm/m (e.g. using NIVELTRONIC instrument)
OR
 Set the sensitivity same as the sensitivity of the instrument and enter the values in digit (e.g.
Minilevel “classic” or Leveltronic “classic”.
When using WYLER instruments 1 digit is corresponding to the sensitivity of the instrument.

Procedure in case IV)
The interface is a LEVELADAPTER 2000 suitable for
the connection of instruments with an analogue
measuring signal
The following options are possible:
 Instrument[A] --> LA2000 --> PC
 Instrument [A - B] --> LA2000 --> PC
 Instrument [A] --> LM25 --> LA2000 --> PC
 Instrument [A - B] --> LM25 --> LA2000 --> PC

for manual input of the values by console
The instruments having been used for the last measurement are proposed again and, provided these are
connected through the same interface and ready for use, the measurement can be performed with these
instruments.
Attention! The LEVELADAPTER 2000 cannot identify the serial number of the instruments connected and
transmit it to LEVELSOFT PRO. The LEVELADAPTER 2000 can NOT be switched between measuring with one
instrument and measuring with two instruments by LEVELSOFT PRO. Therefore it is inevitable to select it as (A)
or (A-B). On the screen the option (A) will be listed as LA2000 (A) the option (A-B) as LA2000 (A) - (B).
LEVELSOFT PRO can also NOT detect whether the measuring instruments are connected correctly and
whether the correct choice (A or A-B) has been made, this remains in the responsibility of the user.
Select the measuring mode with which you intend to measure the object by clicking on the correct icon or use
the correct key. Using [SPACE] accepts the existing set-up.
Page 65 of 197 pages
IMPORTANT for the manual entry (e.g. when no instruments are connected to the PC):
When entering the measuring data manually using the keyboard, it is important
 that the sensitivity is set to 1 µm/m and the measuring value is entered in µm/m (e.g. NIVELTRONIC
instruments)
OR
 that the sensitivity is adjusted to the sensitivity of the instrument and that the measuring data are
entered in digits (e.g. for MINILEVEL "classic" or LEVELTRONIC "classic"). With WYLER instruments
1 digit (least count of the display) corresponds to the sensitivity of the measuring instrument.
SELECT OTHER INSTRUMENTS OR ANOTHER INTERFACE
What to do,
 if in the field [F4] a wrong picture is displayed

if in the field [F4] wrong instruments are listed

if in the field [F4] a measuring instrument is missing

when at the start of a measurement no measuring instrument is found
Connect the measuring instrument to the software.
If the picture to the left of the line [F4] does not correspond to the measuring instruments available or when
LEVELSOFT PRO after unsuccessful initialisation displays the message "no instruments", the instruments
available must be newly connected to the software.
Select [F4]. A dialogue box with the title "Measuring instrument" will appear
Page 66 of 197 pages
In this dialogue box select [F1] ([F2] will not provide a connection for the LEVELADAPTER 2000)
A new dialogue box with the title "Select Device" will appear.
Open the pull down selection "Device"
If the instrument available does not appear in the list this
instrument must newly be connected. First select the COM
port where the instruments are connected (you can even

Page 67 of 197 pages
The LEVELADAPTER has been found and connected.
Attention! The LEVELADAPTER 2000 is listed twice. For
differential measurement select (A) - (B). For
measurements with on instrument only select (A). With
one exception the selection must coincide with the
selection under [F3] in the measuring pattern.
Confirm with O.K.
The instrument selected is shown in the dialogue box "measuring instrument". ([F2] cannot be used.)
Provided that the instruments connected provide 1 mV per digit or division on the scale as measuring unit,
confirm with "continue".
This is applicable for MINILEVEL "classic" A10, for LEVELMETER 25, A25 with e.g. LEVELTRONIC "classic"
A40 but also for MINILEVEL NT11 or LEVELTRONIC NT41 which apart from the digital signal also provide an
analogue output.
Attention: The older LEVELTRONIC A40 must not be connected directly to a LEVELADAPTER 2000! These
must be connected to a LEVELMETER 25 the output of which is linked to the LEVELADAPTER. For this special
case the LEVELADAPTER must be selected with one input LA2000 (A) and the measuring mode must also be
set to one measuring instrument. The calculation of the difference is made in the LEVELMETER 25).
For NIVELTRONIC / nivelSWISS or measuring instruments with analogue output from other sources the relation
of the voltage to the inclination value must be adjusted. For this function select [F4] in the window shown above.
Enter the voltage per digit or division under F1. For NIVELTRONIC / nivelSWISS the voltage is between 15 mV
and 18 mV per division. Newer instruments will be closer to 18 mV, older instruments may be closer to 15 mV.
(After entering a selection, e.g. 18 mV per digit, a simple line measurement serves as control measurement.
Set the display by the potentiometer to minus 10 divisions and read in a measuring value. Then set the display
to plus 10 divisions and read in a value again. If the difference of the two values in the left column of the
LEVELSOFT screen is not equivalent to 20 divisions, the deviation in % must be calculated and the value in F1
must be adjusted with the same percentage).
Confirm twice with "continue.

Sensitivity
When the interface is automatically recognised, also the sensitivity is automatically defined, otherwise it must be
set in the respective box.
4.7.19.5
Limit of variation
Here a limit of variation may be set. When measuring in surrounding conditions not suited for precision
measurement (e.g. vibrations) it may be required to gradually increase the limit of variation. Generally it can be
said the higher the limit of variation the higher the measuring uncertainty, respectively the closure error.
The pre-set value is 5 µm/m, respectively 1 Arc sec.
Additional information concerning “limit of variation” see chapter 3.9 remarks concerning the “Limit of Variation”
4.7.19.6
Surveillance of drift
Due to temperature changes or because of vibrations the zero point of the instrument can drift away. With the

Configuration of the measuring set
Two basic possibilities exist:
Measuring instruments connected to the
Interface by cables
Using the classic configuration the instruments
(MINILEVEL NT und LEVELTRONIC NT) are connected via
cables to the interface (LEVELMETER 2000 or Levelmeter
C25 (analogue Version))
Instruments of the NT series can also directly be connected to
a LEVELADAPTER 2000.
Measuring instruments connected to the
Interface by wireless data transmission
In the configuration of NT instruments with "wireless
transmission" the measuring data will be transmitted by radio
signals to the external display unit (only possible with
LEVELMETER 2000 with radio).
BlueSYSTEM is optimized for wireless transmission of the
data. Nevertheless the instruments can also be ordered
without the radio modules for data transmission by cables.
Those instruments can be upgraded with radio transmission
modules at a later stage.
Page 73 of 197 pages
In the example "measuring a line" the difference between the two options is displayed.
5.1.3
Measuring instruments connected to the Interface
by cables or wireless data transmission
Start the software LEVELSOFT PRO. Define the measuring task. “File/Measuring pattern new/change” as
follows:
 Object:

<Start measurement>
/ or key [F11]
Page 74 of 197 pages
In the configuration with reference measurement the two possible configurations of measuring
and reference instrument appear.
It is recognised that there is a configuration with two measuring instruments with wireless data
transmission. The user is now to decide which one of the two instruments will be used as the
"measuring instrument" respectively as the "reference instrument". The configuration connected is
recognised. Click now on the configuration required or select using the function keys [F1] or [F2].
L0213B – I0314B F1
I0314B – L0213B F2
After the selection the measuring instruments will be initialised accordingly.
The configuration connected will be recognised. The information "ready" is blinking.
For safety reasons you are asked to confirm the selection again with <CONFIRM> / [F1].
If the message "no measuring instruments" or *not enough instruments" appears instead of the
serial numbers, the instruments are not correctly connected / configured. In this case check
whether all the instruments are ready and newly connect them as described in chapter 5.1.4.
Page 75 of 197 pages
After confirmation of the configuration you can start with the actual measurement
It is important to know that all settings, such as measurement with one instrument or reference measurement
must by carried out through the software LEVELSOFT PRO. The settings on the BlueMETER or on the
LEVELMETER 2000 are overruled. During the measurement the keys on the BlueMETER are blocked.
After successful collecting of the measurement data the value will be displayed on the screen for checking in
large letters. When continuing with the confirmation of the value the displayed figures disappear and the next
position for the measuring instrument will be shown.

5.1.5
SWAPPING THE INSTRUMENTS DURING THE MEASURING PROCEDURE
Measuring Instrument >>> Reference Instrument
Reference Instrument >>> Measuring Instrument
During a measuring procedure it may be required to exchange the instruments so that the measuring instrument
will become the reference instrument and vice versa. This may be useful when the instruments are equipped
with different sizes of bases and the flatness of a surface must be measured with different step length
longitudinal and transversal. In such a case the instruments can be exchanged when the longitudinal lines are
measured.
IMPORTANT:
The exchange of measuring instruments during a measurement may only be performed when the measuring
direction will be changed, e.g. from longitudinal to transversal lines in a flatness measurement .If the instruments
are exchanged, e.g. during the measurement of parallel lines, the measuring result will be useless.
Exchange of Measuring Instruments
In configurations where the measuring instruments are connected to
the interface through cables or via wireless data transmission
After the last measurement of longitudinal lines of a granite master plate the option to exchange the measuring
instruments will appear in the status line. Exchange now the two instruments by activating the <EXCHANGE
INSTRUMENTS> button or the function key [F1]. The measuring instruments need not be re-connected through
cables, however, the placing of the instruments must be considered.
If a LEVELADAPTE 2000 is used, the instruments may / must be re-plugged at the LEVELADAPTER 2000.
The function key F1 is not available.
If a LEVELMETER LIGHT or a BlueMETER LIGHT is used, the instruments may / must be re-plugged at the
LEVELMETER LIGHT or BlueMETER LIGHT. The function key F1 is not available.
Page 78 of 197 pages
After such an exchange of the instruments after termination of the measurement of longitudinal lines the
software will recognise that the initial configuration has been changed. The new configuration will be displayed
in the status line.
Configuration of measuring instruments before the exchange:
L0213B – I0314B
Configuration of measuring instruments after the exchange:
I0314B – L0213B
The measurement can now be continued.
NOT APPLICABLE when using a LEVELMETER LIGHT, BlueMETER LIGHT or LEVELADAPTER 2000!

Special option when measuring 2 parallels.
Before starting the measurement LEVELSOFT PRO offers a correction window. Here an offset can be entered.
This offset will be considered when calculating the parallelism.
Purpose: When e.g. two opposite vertical parallels must be measured a special measuring instrument with two
vertical bases or a frame base must be used. This correction option allows considering the error of parallelism
between the measuring bases of the instrument.

Measurement of Flatness
5.6.1
Surface "Surface Grid (WYLER)" DIN 876 / Part 1 (Grid)
Remarks concerning the flatness measurement:
a) Standards
Please consult DIN 876 / Part 1, when measuring flatness
b) Measuring steps
The object to be measured must be adjusted horizontally in both directions (longitudinal and
transversal) as well as possible (within approx. 50 µm/m). If not done so measuring errors may occur if
the measuring instrument is not placed exactly in line with the measuring direction.
The object must now be divided in the measuring step length. The step length has to be such that an
equal dimension of overlapping of the base length with each step is possible. At the same time the
optimal step length as described earlier must be considered.
The best possible step length when using a 150 mm base is 126 mm.
As a guideline it should be noted that the worse the surface quality (roughness, buckling) the more
important is a precise overlapping in order to avoid measuring errors. When calculating the measuring
steps it is important to make sure that the base as a whole comes to lay on the surface when placed at
the first and last measuring position (no protrusion) as this would also cause unacceptable measuring
errors.
The grid is to be marked on the surface plate with a pencil that does not apply a thick layer. This is
especially important doing high precision measurements.
Example:
Measuring object: Granite surface plate 1200 x 800 mm
Measuring instrument:
Minilevel or Leveltronic, horizontal model
Base length of the instrument is: 200 mm
optimal step length is 170 mm
Pattern of measurement:
Surface Grid (WYLER)
Step length longitudinal:
190 mm
Step length transversal:
185 mm
No. of longitudinal lines:
5
No. of transversal lines:
7
(Calculation of the grid see below)
Remarks concerning the pattern of measurement "SURFACE"
Four different patterns for measuring flatness are available:
see chapter 5.6.2 Rectangle
1. Rectangle
this chapter
2. Surface grid (WYLER)
see chapter 5.6.3 Measuring of surfaces according to the
3. U-Jack
method "US Union - Jack"
see chapter 5.6.4 Measurement of partial surfaces
4. Partial surface
Page 102 of 197 pages
In our example the calculation was based on the border zone of 20, resp. 30 mm on the side. The remaining
distance is divided by the optimal step length, and then the figure set to either the next higher or lower round
figure. The originally defined remaining distance must now be divided by the new fixed number of steps whereas
the newly calculated figure is the step length to chose.
1200 mm - (2 x 30 mm) = 1140 mm
1140 mm / 170 mm = 6.7 steps = 6 Steps; 1140 mm / 6 = 190 mm step length longitudinal
The same method is to be applied for the other direction with a length of 800 mm
On the side of the base the step length may be marked. Also the middle of the base may be marked at the front
and at the end. By doing so it is assured that the measuring instrument is always placed correctly at the spot
required.

 U-Jack / US-Standard "GGG – P – 463 c"
This method is mainly used in the US and in the UK. The mayor disadvantage compared with the
“WYLER” method according to DIN 876 / Part 1, is the fact that the total surface of the object is not
covered optimally.
 Partial
Partial surface based on the measuring object "Surface WYLER"

In our example in the first proposal a remark is seen by the display of the border zones "Attention border zone!".
This means the size of the border zone respectively the dimension from the object’s edge to the first measuring
line is larger than allowed according to DIN 876.
Further procedure:
4. Using the function "More Grid Proposals" a selection of additional grid proposals is displayed. Those
proposals which are possible but do not fully comply with the respective standards (Border zone not
according to standards) are marked in red. By clicking to the respective column header the data can be
sorted according to the values in the respective column.
Meaning of the different columns (left to right):
Step length / Number of measurements / Measuring density / Border zone
The chosen grid proposal should now be marked after checking if the border zone is within the tolerance
required.
Next step:
5. Using the Slide control unit "Change Measuring Density" long and cross the density may be changed.
By doing so new proposals will be computed. Default is that every line longitudinal and transversal is
measured.
In our example we do not change the measuring density, we measure all the lines of the grid.
Remarks concerning border zone longitudinal, transversal:
The smallest possible border zone is 22.5 mm. This is half of the base width of our instruments. This value can
not be reduced.
Using OK the proposed solution is accepted for continuation in the appearing windows.
Page 110 of 197 pages
The selected values will be incorporated and with <Continue> / [SPACE] the grid layout will be accepted. In case
it should not be satisfactory
 individual values can be changed in this window
 the <Grid proposal> / [F9] can be selected from new.
Page 111 of 197 pages
The other steps are identical to measuring a line:
 Way of measuring
 Limit of variation
 Surveillance of drift
 Starting the measurement with / without saving of the measuring pattern
is identical to the procedure of measuring a line.
The measurement can now start by using <Start measurement> / [F11] (without saving of the measuring
pattern), or using [SPACE] for <Save and start measurement>
After successful collecting of the measurement data the value will be displayed on the screen for checking in
large letters. When continuing with the confirmation of the value the displayed figures disappear.
Repeat measurement:
 After the actual collecting of the measured value the measurement can be repeated
by using <REPEAT> / [F1]
 After confirming the latest individual measuring value it is possible to
use <BACK> / [F2] and then all the values of the whole last measured line can
be measured again.

Flatness of the surface according to ISO 1101, with correction of closure errors PHILIPS
The maximum error of the surface is reduced to 2.4 µm. Instead of the closure error the display shows now the
“Index of correction” which is corresponding to the standard deviation of all the closure errors.
In our example the selected standard is DIN 876 and the quality of the flatness corresponds to grade “00”. The
standard may be changed by using <Options> / [F7]. The display may also be completely omitted. Additional
information to the Quality standards is available in chapter "4.7.17 Changing of flatness standards".
For flatness measurement according to WYLER only the alignment method
according to ISO 1101 comes into use!!!
Remarks:

By using the symbol
the closure error (Philips correcting program) can be shown.
Flatness of the surface, aligned according to ISO 1101, without correction of the closure error.
The maximum flatness error is 2.79 µm, the closure error is 0.91 µm.
The closure error is an indication of the quality of the measurement. The presentation of the quality and the
grade is not possible in this display.
Remarks concerning the correction of closure errors:
 After the finishing of the measurement it is important to view the display in profile without the Philips
correction. The closure error is an important indication on the quality of the measurement.
 As a general rule the closure error should not be more than 20% to 25% of the maximum error.
If the maximum error is less than 4 µm the closure error may exceed the above-mentioned values.
 In our example the closure error is 26% of the maximum error (1.07µm related to 4.03µm), however the
maximum error is only 4.03 µm therefore the measurement’s quality is just acceptable.
The closure error correction according to Philips is a mathematical process in which measuring errors with linear
increasing characteristic are visually eliminated.
The index of correction displayed after the corrective action gives an indication of the success of the
measurement. (The index of correction is the result of all the standard deviations of the closure errors)
The displayed index of correction must be considered in the definition of the measuring uncertainty

MEASUREMENT OF SURFACE RECTANGLE / MEASUREMENT OF GUIDE WAYS
General remarks:
The procedure concerning preparation, setting parameters and measurement are identical to the measurement
of a surface “WYLER Grid” described in chapter 5.6.1. The only but important difference lays in the different
alignment method.
The measured object is aligned in a way that the two endpoints of the first longitudinal line and the two
endpoints of the first transversal line are on the same level.

An additional method of measuring a surface is according to the so-called US-U-Jack principle. This method is
mainly used in the US and in the UK. The mayor disadvantage compared with the “WYLER” method according
to DIN 876 / Part 1, as described in chapter 5.6.1, is the fact that the total surface of the object is not covered
optimally.

(A possible layout could be as shown below)
The layout must be so that:

 the layout always follows the same pattern (as seen above) The number of steps as well as the
step length can change.(The step length of the longitudinal, the transversal and the diagonal
lines can be different)
 the three longitudinal and the three transversal lines must be symmetric. Therefore always an
even number of steps are used.
 the US standard "GGG – P – 463 c" must be observed
 the layout connecting errors in the corners must be less than 8 mm, respectively 0.3 Inch.
Page 121 of 197 pages
Remarks:
 The instruments may be exchanged, e.g. due to the required size of the base length, during the
measurement of the surface after the measurement of a set of lines.
 Please consult the US-standard "GGG – P – 463 c"
 In contrary to the measurement according to the "WYLER” method, DIN 876 / Part 1, when using the

Page 122 of 197 pages
For our example we chose
<U-JACK> / [F4]
The mask for entering the parameters is displayed.
With first priority the division of the longitudinal lines and the transversal lines must be determined.
For longitudinal lines:
length = 1200 mm, minus 2 X border zone (2 x 60 mm) = 1080 mm, in order to enforce an even number of steps
divide 1080 mm by 2 = 540 mm.
4 measuring steps of 135 mm = 540 mm. For the complete line = 8 measuring steps of 135 mm each.
Use the same method to calculate the number and length of the measuring steps for the transversal lines
The result = 6 measuring steps of 120 mm each.
The values calculated must now be entered in the respective input field.
The software will provide a measuring layout (basic setting) without considering the possible step lengths for the
available instruments in the diagonal lines. By changing the number of measurements diagonal you must now
find a suitable solution. (Only an even number is permitted.) With 10 measuring steps you get a step length of
129.8 mm. For this step length the measuring base of 150 mm can be used.

After selection the result is displayed in the monitor (top right) and can be used for checking the result.
You can now <Continue> by using [SPACE]

 Start measurement, with/without saving the measuring pattern
are identical to measuring a line.
The measurement can now start by using <Start measurement> / [F11] (without saving of the measuring
pattern), or using [SPACE] for <Save and start measurement>
After successful collecting of the measurement data the value will be displayed on the screen for checking in

Page 124 of 197 pages
After the last measuring step the following screen will appear. With the icon <Pre-view> / [F2] the measured
pattern can be viewed without completing the measurement definitely.
Based on this pre-view the user can decide to repeat the measurement of one of more lines.
In order to do so, use the key <Repeat Measurement> / [F2].
Page 125 of 197 pages
Click with the mouse on the line, resp. lines, you intend to measure again and confirm your selection with
<Confirm> / [F1]. In our example we will repeat the measurement of the third longitudinal line.
The respective line can now be measured again. After completing the measurement the menu <Pre-view> / [F2]
will allow again to repeat the measurement of one or more lines.

70mm … 270mm (extended range)
The U-Jack pattern must be laid out so that
 the step length is corresponding with the available base of the measuring instrument
 the layout is done always according to the same pattern (see above) The number of steps and
the length of the steps can vary, the step length of the longitudinal, the transversal and the
diagonal lines can be different
 the three longitudinal and the three transversal lines must be symmetrical this means that
always an even number of steps is used
 the US-standard "GGG – P – 463 c" is applied
o one line must have at least 6 steps
o the step length should not be bigger than 12“ (300 mm)
o every line has an even number of steps
o the connecting area at the crossing of the individual lines must not be larger than within
a diameter of 0.3” (8mm)
o Border zone
 For diagonal line length between 12 and 48“ the maximum allowable border zone is
1“ (25.4 mm)
 For diagonal line larger than 48“ (1219.2 mm) the maximum allowable border zone
is 1.5“ (38.1 mm)

The flexible base of WYLER
For many years we have faced customers’ requests
for WYLER instruments with a measuring base
allowing adjustable step length. Considering the
technical requirements and in order to avoid any
negative influence of such a base on the quality of the
measuring results, intensive tests with a variety of
models and versions have been performed.
As a result of this development series we are now in a
position to launch the WYLER Flexbase. The users
will be excited by the easy handling and the multiple
options available. This base is conceptually adopted
from the standardised 3-point-supported measuring
bases, which also makes the use of the U-Jackmethod a lot easier.
Particularly in combination with the latest version of
our software LEVELSOFT PRO this measuring base
is a convincing enhancement. This software allows
the automatic calculation and proposal of a suitable
measuring layout in an easy way, taking in account
the high variety of possible step lengths provided by
the Flexbase.
Additional advantages
 The base features a scale, allowing an easy adjustment of the step length
 Easily visible marks allow a precise positioning of the base during the measuring procedure
 Experienced users can easily displace and re-adjust the support plates for enlarging the range of possible step
lengths considerably
Technical data of the WYLER flex base:

Base length and width: 250 x 45mm

Adjustable step length standard 90 (100)mm to 240mm

Extended step length 70mm to 270mm

Dimensions of 3-Point Tungsten carbide base: Diam. = 0.4”, Distance width = 1.4”

3. With <Calculate>a first proposal will be generated
The software is now calculating a first series of possibilities using the base length set (In our example WYLER
flex base 100 … 240mm)
The data will be displayed in the monitor lower left side and can be used for a check
In a first step the following parameters will be computed
 Step length diagonally:
235mm
 Step length longitudinal:
195mm
 Step length transversal:
130mm
 Number of measurements diagonally:
6 total
 Number of measurements longitudinal:
6 total
 Number of measurements transversal:
6 total
 Border zone longitudinal:
15mm
 Border zone transversal:
10mm
In addition the following information is displayed in the monitor
 Half length of the longitudinal lines
3x195mm = 585mm
 Half length of the transversal lines
3x130mm = 390mm
 Distance of beginning and end point of the diagonal
o Distance from border longitudinal
10mm
o Distance from border transversal:
10mm
Page 144 of 197 pages
The beginning and endpoint of the diagonal is not in every case on exactly the same spot as the longitudinal
respectively the transversal lines are. According to the specification the crossing points must lay within an area
with a diameter of 8 mm respectively 0.3”. The graphic below gives additional information to this.
Drawing the layout:
1. Step:
Drawing of the diagonals (starting at 5 mm transversal / 5 mm longitudinal)
2. Step:
Drawing the definite diagonals with the step length of 235 mm
Drawing of the longitudinal and transversal lines starting at the centre by applying the correct border zone
(starting at 5 mm transversal / 5 mm longitudinal) and step length. The longitudinal and the transversal lines are
always meeting at the same spot.

INFORMATION ABOUT THE MEASURING PROCEDURE WITH A WYLER FLEX BASE
The U-Jack measuring procedure with a WYLER flex base
In order to measure the object in total length and width it is of greatest importance to turn the measuring
instrument as well as the reference instrument at certain positions 180° around. The user will be guided to do so
by means of a displayed picture during the measuring procedure.
As seen in the above picture the measuring as well as the reference instrument must be turned by 180°, without
lifting the instruments off the plate, coming to the first transversal line and coming to the third longitudinal line.
These positions are marked above with dotted lines.
IMPORTANT:
The reference instrument (R), if used, must always look in the same
direction as the measuring instrument.
Page 149 of 197 pages
The measurement can now start by using <Start measurement> / [F11]
Start measurement, with/without saving the measuring pattern is identical to measuring a line.
After successfully collecting the
measurement data the value will be
displayed on the screen for checking in
large letters. When continuing with the
confirmation of the value the displayed
figures disappear and the new position
where the instrument must be placed is
seen.
For the first two measuring lines the
measuring as well as the reference
instrument is set in measuring direction.
The two base pads must be placed
symmetrically and precisely on the
crossing points. (see sketch)
For the measurement of the third
longitudinal line the measuring as well
as the reference instrument must be
turned by 180°. This means the
connectors of both instruments are
looking opposite to the measuring
direction.
Page 150 of 197 pages
For the measurement of the first
transversal line the measuring as well
as the reference instrument must be
turned by 180°. This means the
connectors of both instruments are
looking opposite to the measuring
direction.
For the measurement of the second and
third transversal line as well as the
diagonal lines the measuring instrument
as well as the reference instrument
must be turned to have the WYLER
standard position. This means the
connectors on the instruments are
looking in the measuring direction as
usually set so.
Page 151 of 197 pages
After the last measuring step the following screen will appear. With the icon <Pre-view> / [F2] the measured
pattern can be viewed without completing the measurement definitely.
Based on this pre-view the user can decide to repeat the measurement of one of more lines. To do this action
the key <Repeat Measurement> / [F2].
Page 152 of 197 pages
Click with the mouse on the line, resp. lines, you intend to measure again and confirm your selection with
<Confirm> / [F1]. In our example we will repeat the measurement of the third transversal line.
The respective line can now be measured again. After completing the measurement the menu <Pre-view> / [F2]
will allow again to repeat the measurement of one or more lines.

MEASUREMENT OF THE SQUARENESS OF A GRANITE MASTER SQUARE
Measuring task: Measurement of the squareness of a granite master square with previous determination
of the instrument’s angular error by using a granite parallel block in quality 000.
Procedure as per WYLER / SCS standard
A detailed calibration procedure is available upon request for this standard procedure,
developed by WYLER AG and accredited by the Swiss Accreditation Service.
Such a calibration procedure will be supplied at a nominal charge.
Remarks:
The calibration procedure mentioned is especially for the squareness measurement of different objects, mainly
for master squares (WYLER Standard delivery programme) and similar objects.
Requirements:
 Accessories
o Granite surface plate / the flatness of the reference surface must be better than 50% of the expected
angular error
o Master granite parallel block (Quality 000)
o The reference surface of the square to be measured must be concave, this means the master
square to be measured must have the contact points close to the end of the reference surface.
 Environmental conditions
o Climate controlled measuring laboratory
o The measuring instruments as well as the object to be measured must have been for at least two
hours in the laboratory for proper acclimatization.
Restrictions:
 The procedure is only acceptable for objects with surfaces min. 50 mm wide
 If the angular error is more than 2 µm/m, then the allowable error of each of the surfaces of the square must
be less than 60% of the angular error.
 The max. angular error must be less than +/- 100 µm/m
Principle of the measurement
 The flatness of both surfaces of the object enclosing the 90 degree angle must be measured according
the standard calibration procedure WYLER "SCS_03.doc"
 The angular error of the measuring instrument must be determined according to the calibration
procedure "SCS_WI1.doc"
 Measurement of the 90 degree angle of the master square and computing the angular error considering
the calibration procedure "SCS_WI2.doc", the definition of the angular error is done according to
ISO 1101.
Page 173 of 197 pages
In the following example the procedure is explained in detail.
General procedure of the measurement
 The existing angular error of the measuring instrument is to determine by using a master granite
square (this is not a must)
 After this the actual measurement is done according to the requirements in different steps as

reference instrument), the determination of the angular error of the measuring instrument
must be performed with one instrument only, the measuring instrument featuring an angular
base. Please assign the measuring instruments as measuring respectively reference instrument
well from the beginning when setting up the measuring configuration.
The reference instrument is deactivated during the determination of the angular error.
Definition of the measuring
respectively reference
instrument:
measuring instrument
reference instrument
With [Continue] or [Space] the measurement will be started. The reading method only considers the measuring
instrument, the reference instrument is deactivated.
After that you perform the actual reversal measurement with the angular measuring instrument.

At the end of the reversal measurement the
determined angular error as well as the individual
values will be displayed
With <Continue> or the key [SPACE] the values will be incorporated in the measurement to follow.
To continue the display shows that the two instruments are activated for differential measurement again.
The display makes you aware that for the following measurement the reference instrument will be activated
again and you can now start the actual measurement.
Important remark:
For master squares planned to be used mainly in "upright" position on a reference surface the
measurement of one side can be done on a defined reference area of a surface plate.
The flatness of this reference area must be better than 50% of the expected angular error.
It is important that the contact points of the master square to be measured must be close to the end of the
reference side (defined support).
Page 180 of 197 pages
At the end of the measurement the result is displayed
Contrary to the other measurements of 90 degree angles the alignment method used for the reference line of
the master squares is exclusively according to “ENDPOINTS”. The mayor reason being the fact that the
reference line is required to be concave. Therefore the results would be the same no matter what alignment
chosen.
The error of the reference line is 0.05 µm
The angular error of the second line is displayed in 3 different ways. Thereby please be aware that in case of the
SCS calibration the alignment method used is according to ISO 1101 or according to the method “Endpoints”.
The error according to "linear regression" is for information purposes only.

5.9 LINE ABSOLUTE / MEASUREMENT OF AN OBJECT WITH VALUES ABSOLUTE
Purpose of this measurement:
The intention is to use a suitable measurement for setup an object to a horizontal position, respectively to define
the actual position of an object in the space.
In order to do so a line is to be measured with absolute values determined. (Absolute in relation to the centre of
the earth). After the measurement the object is to be aligned according to the endpoint method to setup
horizontally.
5.9.1
Measurement with Mini T/C without radio transmission, by means of cable connection
(Using T/C with radio transmission see pt. 5.9.2)

Points for adjustment:
Measurement 4 + Measurement 12
Base length instruments:

IMPORTANT:
When measuring a LINE ABSOLUTE the following points must be regarded:
 The measurement can only be done with one instrument, (no differential measurement)
 The interface between the measuring instrument and the PC must be one of the following:
o BlueMETER or BlueMETER BASIC with/without radio module, communication required in both
directions
o Levelmeter 2000 with/without radio module, communication required in both directions
o Mini T/C (Mini Transceiver/Converter) with/without radio module
Configuration of software LEVELSOFT PRO:
After starting the software the following windows appears with the last used measuring pattern. In our example
the flatness of an object was measured.
Page 182 of 197 pages
To setup the required measuring task open the menu point “File / Measuring pattern New / Change”.
The different positions must be adjusted:
 Object
 Way of measuring
 Instrument, (LEVELMETER 2000 will automatically be recognised)
 Sensitivity, when using LEVELMETER2000, sensitivity will automatically be recognised and appears on
the screen in a frame
 Limit of variation
 Surveillance of drift (For measuring LINE ABSOLUTE, not possible)
 Limit of drift admissible (Only when surveillance of drift is active)
As a first step the actual measuring object must be changed by a mouse click to "Object" or key [F1].
As a first step the actual measuring object (Surface

You return to the measuring pattern where the new set up is displayed
"Instrument [A]" is now set.
As "measuring instrument" the symbol of the LEVELMETER 2000 (Mini-T) with or without radio transmission as
well as the serial number of the MINILEVEL NT connected.
As a next step the Limit of variation can be set.
After defining this new configuration, respectively the new measuring pattern the following procedures are now
possible:
 With <SAVE MEASURING PATTERN> [F10] you can save the configuration for later use as a
measuring pattern without starting the actual measurement.
Such a procedure makes sense when first a number of different patterns will be defined for later use.
 With <START MEASUREMENT> [F11] you start a measurement without saving as measuring pattern
 With <SAVE AND START MEASUREMENT> / [SPACE] you will be asked to save the configuration as a
measuring pattern before starting the measurement
Page 185 of 197 pages
After starting the measurement <START MEASUREMENT> [F11] the determination of the instrument’s
ZERO-OFFSET is started. This determination is done by means of a reversal measurement. (See sketch below)
Such a reversal measurement is best done on a horizontally adjusted surface plate
Before starting the reversal measurement the instrument must be correctly recognised, the address is to be
carefully checked. In our case the address is “3”. This is especially important, when using radio transmission.
Confirm with [F1].
After this the actual reversal measurement can start.
Value "A" is collected.
Page 186 of 197 pages
Value "B" is collected.
At the end of the reversal measurement
the determined angular error (ZEROOFFSET) as well as the individual
values will be displayed
In case the values are reasonable the measurement can now be started by using <Continue> / [SPACE]
Remarks:
The defined ZERO-OFFSET (Zero offset of the instrument) is automatically stored in the
instrument. This means that the instrument can be disconnected from the system and the
instrument will display the correct measured values absolute.
In case the reversal measurement is not finished completely the “old” ZERO OFFSET remains
in the instrument stored.

6.1
DETAILED INFORMATION CONCERNING THE THEME "ALIGNMENT OF COMPLEX MEASURING OBJECTS"
As described in chapter “3.8 Methods of alignment” a number of different principles are available when lines are
concerned. The same basics do apply when angles are measured. The task is somewhat more complex due to
the second dimension involved.
For all the angular measurements the following applies
1.
The reference measurement is done and then aligned horizontally respectively vertically according
to the known methods
 Alignment according to the method “Endpoints”
 Alignment according to the method “ISO 1101”
 Alignment according to the method “linear Regression”
2. The second line measurement is “turned” accordingly (the same angle as the reference line is
turned). The angular error may now be computed again according to the three different methods
The following graph should explain the situation:
In the graph the three different methods are displayed.
Alignment according to the
method "Endpoints"
In this method the first and the last measured point are connected by a
straight line. The whole figure is now turned horizontally. The connecting
line is moved parallel to the highest and the lowest point of the object. The
vertical distance between the two lines is the maximum error calculated
according the method “Endpoints”.
Alignment according to the
method "ISO 1101"
In the method ISO1101 two parallel lines are aligned in such away that the
distance between them is the least possible.
The vertical distance between the two lines is the smallest possible error
according the method “ISO 1101”
Alignment according to the
method "linear Regression"
Using the method “linear regression” a straight line is calculated out of a
number of measuring points according to the method least square.
The so calculated line is moved parallel to the highest and the lowest point
of the object. The vertical distance between the two lines is the maximum
error calculated according the method “Linear regression”.
Page 191 of 197 pages
The angular error is defined by one of the three methods, in our example first the reference measurement line is
aligned according to the method “Endpoints”
Then again three methods of alignments of the second line exist so that three angular errors may be determined.

INFORMATION ABOUT "SYMMETRIC, RESPECTIVELY ASYMMETRIC LAYOUT" OF
THE MEASURING AREA
Three possibilities exist for measuring a flatness area of an object
 Symmetric layout of the measuring area
The measuring instrument will be guided on the centreline of the flat base throughout the measuring
area of the plate. In this case the grid is laid out symmetrically on the object.
 Asymmetric layout of the measuring area for WYLER standard measuring bases
The measuring instrument will be guided along a side of the base throughout the measuring area of the
plate. In this case the grid is laid out asymmetrically on the object.
 Asymmetric layout of the measuring area for WYLER 3-point screw-on base
The 3-point base measuring instrument will be guided on the centreline of the contact points throughout
the measuring area of the plate. In this case the grid is laid out asymmetrically on the object.
a) Measuring instrument with flat base and symmetric layout guidance
The measuring grid is drawn symmetrically on the
object
The measuring instrument will be guided on the
centreline of the flat base throughout the
measuring area of the plate.
Using <Grid Proposal> equal border zones are to
be chosen, which means symmetric layout
Symbol
Symmetric
layout
In this example the border zones are symmetric
 Border zone left and right identical
30 mm each
 Border zone near and far identical
30 mm each
Page 194 of 197 pages
b) Measuring instrument with flat base and asymmetric layout guidance
The measuring grid is drawn asymmetrically on
the object
The measuring instrument will be guided along a
side of the base throughout the measuring area of
the plate
Using <Grid Proposal> unequal border zones are
to be chosen, which means asymmetric layout
Symbol
In this example the border zones are asymmetric
(have not the same dimension)
 Border zone left
7,5mm
 Border zone right
52,5mm
 Border zone near
7,5mm
 Border zone far
52,5mm
Asymmetric grid layout
(in the direction of lower left corner)
Advantage:
More precise measurement due to the easy visible
guide of the lines
Disadvantage:
Asymmetric Grid
Page 195 of 197 pages
c) Measuring instrument with 3-point base and asymmetric layout guidance
The measuring grid is drawn asymmetrically on
the object
The 3-point base measuring instrument will be
guided on the centreline of the contact points
throughout the measuring area of the plate.
Important:
The first contact point in longitudinal direction
and in transversal direction must be identical!!
Symbol
In this example the border zones are asymmetric
(have not the same dimension)
 Border zone left
52,5mm
 Border zone right
7,5mm
 Border zone near
7,5mm
 Border zone far
52,5mm
Contrary to option b) the layout is drawn in the
direction of the lower right corner. The border
zone is left larger than right!
Asymmetric grid layout
(in the direction of lower right corner)
Advantage:
More precise measurement due to the easy
visible guide of the lines
Disadvantage:
Asymmetric Grid
