Calibration For Diameter Measurement; Matching Of A Probe And A Unit - sylvac D50S Mode D'emploi

3.2. Calibration for diameter measurement

The unit can be calibrated to measure internal diameters. 2 setting rings with
different sizes are required to perform the calibration. Use the smallest ring as
Reference 0 and the biggest ring as Reference 1. The value to insert corres-
E
ponds to the difference between both diameters. Once the calibration done,
insert the value of the small diameter in the Preset menu.
3.3. Matching of a probe and a unit (option available only on D50S PRO)
To increase the measurement's accuracy, it's possible to match each channel
of the unit with its corresponding probe. This operation is independant of the
calibration. It defines a correction curve of maximum 26 points on the probe's
measuring range and specifies a correction for each point. This is to be re-
peated for both channels if required.
Exemple of correction
1) Probe P25 with D50S-PRO without correction —> max error 1.4 μm
2) Same instruments, but with correction of 10 points (every 2.5 mm—> max.
error 0.7 μm
