Description
1.7 Probe, calibration body, calibration tool
Calibration, calibration tool
A probe must be calibrated before it can be used. Calibration involves precisely determining
the triggering points (switching points) of the tool probe and entering them in special data
fields.
Calibration is performed with a calibration tool. The precise dimensions of the tool are
known.
Use the same measuring velocity for calibrating and measuring.
Measurement version Calibrate probe (CYCLE971) (Page 202) is ready for calibration.
