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,
see this chapter ).
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.

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.
Position Description
A Neutral position
B
C
Travel to the upper (resp. lower) trigger point for determination of the value
Partial measuring span for detecting the culmination point
D Travel in one direction from the neutral position to the end stops.
