Parameters
MEASA Measurement with deletion of distance-to-go
MEAWA Measurement without deletion of distance-to-go
MEAC Continuous measurement without deleting distance-to-go
Axis Name of channel axis used for measurement
Mode Two-digit setting for operating mode consisting of
Measuring mode (ones decade) and
0: Mode 0: Cancel measuring job
1: Mode 1: Up to 4 different trigger events can be activated
concurrently. Trigger events
2: Mode 2: Up to 4 trigger events can be activated consecutively
3: Mode 3: Up to 4 trigger events can be activated consecutively
