4 Getting started
4.1 Setting into operation
The section § 13 will give you detailed information about application and adjustments.
1. To switch on the instrument, press the On/Off key.
To switch it off, press the same key (> 2 sec.).
2. The display will ask for the reference. Move the
measuring carriage slowly until the small triangular
reference symbol has been passed. An acoustic signal
will confirm that the reference has been detected and the
display starts counting.
If the display does not start counting, repeat the
sequence.
3. The instrument is now asking for the probe constant. This
function compensates the dimension and the deflexion of
the measuring insert when probing downwards and
upwards (reversed surfaces, diameters), Position the
measuring insert between the two surfaces of the setting
gauge. Do not move the instrument and the setting
gauge any more.
Note:
This procedure may be interrupted by pressing .
The last stored probe constant value will then be
considered.
4. Position the insert on the lower surface of the gauge
using the handwheel for the displacement, engage the
measuring force until confirmation of measurement by
the green direction arrow and a simultaneous acoustic
signal.
5. Without moving any part (instrument and gauge), move
the measuring insert towards the top and perform the
same sequence on the upper surface of the setting
gauge.
6. Repeat the sequences 4 and 5 one more time. This
allows to determine the measurement uncertainty based
on the type of the measuring insert used. The resolution
of the display will automatically be adapted to the
measurement uncertainty.
2 x
7. The probe constant will be displayed on the screen and
stored into the buffer (CST).
The instrument is now ready for use.
The probe constant needs to be checked and stored again after each measuring insert change,
after change of its position in the holder, after each adjustment of the measuring force or
adjustment of the floating probe suspension.
