The following additional parameters are also valid:
_VMS, _TZL, _TSA, _PRNUM and _NMSP.
_TZL, _TSA not for incremental calibration!

Meaning
0 Calibrate tool probe (machine-related)
10
Calibrate tool probe (workpiece-related)
10000
Calibrate tool probes incrementally (machine-related)
10010
Calibrate tool probe incrementally (workpiece-related)
1...3 Number of the measuring axis
103, 203 Number of the offset and measuring axis
102, 201 (not for _MVAR=10000 and _MVAR=10010)
>0 Measurement path
<0 For incremental calibration (_MVAR=1000x0) the travel direction is also
defined via _FA.
_FA > 0: Travel direction +
_FA < 0: Travel direction -
REAL, ≥0 Offset
The offset affects calibration of 3rd measuring axis if the calibration tool
diameter is larger than the upper diameter of the probe. Here the tool is
offset by the tool radius from the center of the probe, minus the value in
_ID. The offset axis is also specified in _MA. Parameter _ID should usually
set to 0.
