Programming example

Calibrating a workpiece probe in the X-Y plane, known hole center point
Workpiece probe 3, used as tool T9, D1, is to be recalibrated in a known hole with
MPx=100,000, MPy=80,000, D=110,246 mm
in axes X and Y in both axis directions with G17 and paraxially (to redetermine trigger values
_WP[i,1] to _WP[i,4].
The positional deviation (skew _WP[i,7], _WP[i,8]) and precise ball diameter _WP[i,0] of the
probe is also to be ascertained.

Meaning
Calibration variant
Calibration setpoint = diameter of hole
Meas. axis, only for _MVAR= xx1xx01, = xx2xx01
(only 1 axis or only 1 axis direction)
Meas. axis, only for _MVAR= xx1x01
(calibrate one axis direction only)
Probe number
Starting angle, only for _MVAR= 1xxx01
(calibration performed at this angle)
