1.7 Calibration of the unit

1.7.1 General calibration

The D100S units are calibrated at the factory. However if a recalibration is required, proceed as follows:

1/ Attach a P5, P10, P25 or P50 probe to a vertical support.

2/ Select a resolution of 0.0001 mm/0.00001 in.

3/ With the probe in its fully extended contact-free position, reset display to zero (Preset key).

4/ Mechanically position probe under reference base so that readout indicates a measurement:

- for P5, between 0.7 & 0.8 mm
- for P10, between 0.4 & 0.5 mm
- for P25, between 0.8 & 0.9 mm
- for P50, between 1.0 & 1.2 mm

5/ Switch off unit, then switch on by pressing

key for four seconds. The following display will appear:

The date of the last calibration is shown.

6/ Place probe on reference base (value 0). Press

7/ Insert 5 mm test block for the P5, a 10 mm for the P10, a 25 mm for the
P25 and a 50 mm for the P50.

8/ Enter exact value of pad on keyboard: 5, 10, 25 or 50 mm,

then press

The calibration value is automatically stored and can only be deleted by a new calibration (changing lithium module or
accumulator does not effect the calibration).

1.7.2 Coupling probe to unit

The user can couple the probe-unit couple and correct from 2 to 25 points linearly.

Example of correction:

1/ Probe P25 with D100S without correction max. error 1.4 µm:
