Instruction manual for MH & MH+M

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.
2.8 Electric power
supply
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.
2.9 Measuring
system
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
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.
