Calibration, gauging block
Figure 2-6
A probe must be calibrated before it can be used. When being calibrated, the trigger points
(switching points), position deviation (skew), and precise ball radius of the workpiece probe
are determined and entered into the corresponding data fields of the general setting data
SD 54600 $SNS_MEA_WP_BALL_DIAM .
The default setting has data fields for 40 probes.
