Calibration, gauging block
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.
Measurement version Calibrate probe (CYCLE982) (Page 178) is ready for calibration.
For lathes, the calibration tool is treated like a turning tool with cutting edge position 3. The
lengths refer to the ball circumference, not to the ball center.
