Parameters Description
Measuring direction Measuring axis (for measuring plane G18)
● +/- Z
● +/- X
Z0 / X0 Reference point Z/X (corresponding to the measuring direction)
DFA Measurement path
TSA Safe area for the measurement result
Note
When the calibration is performed for the first time, the default setting in the data field of the
probe is still "0". For this reason, the TSA parameter must be programmed > probe ball radius
to avoid the alarm "Safe area exceeded".
List of the result parameters
The measuring variant "Radius on surface" provides the following result parameters:
