Selecting the probe number and the calibration data set number
Workpiece probe calibration data fields can be selected using this function. For different
measuring situations, in order to guarantee a high measuring accuracy, it may be necessary
to save the corresponding calibration data in different data fields, which can then be selected
for the measuring tasks.
If the probe number selection is not activated, then probe number "one" is always used.
Entering the calibration feedrate
The actual calibration feedrate can be entered into this entry field. The calibration feedrate is
stored in the calibration data and is used for the measurements.
If the entry field does not exist, then the calibration feedrate from a central parameter is
used.
Selecting the work offset as basis for the measurement
A work offset can be selected as measurement basis to flexibly adapt to the measuring
tasks.
If the work offset selection as measurement basis is not activated, then the measurement
refers to the currently active work offset.
Measuring sequence
To obtain the desired measuring results, you must keep to the measuring point sequence
shown in the help displays.
You can reject measuring points and then measure them again. This is done by pressing the
softkey that is currently active (measured value).
Measuring only
If you "only" want to measure the workpiece zero, the measured values are calculated and
displayed without changing the coordinate system.
Work offset
You usually store the measured workpiece zero in a work offset. The HMI allows rotations
and offsets to be measured.
