Only for offset in tool, otherwise parameter = ""
3)
Only for offset in tool and dimensional tolerance "Yes", otherwise parameter = 0

addition, in the general MD 18080 $MN_MM_TOOL_MANAGEMENT_MASK , bit8 must be set to 1.
If WO "fine" has not been set up in MDs, correction is according to WO "coarse"

Offset in tool geometry:
7)
For measurement in the plane (S_MA=1 or S_MA=2) Offset in tool radius
For measurement in tool direction (S_MA=3) Offset in tool length L1
Empirical averaging for tool offset and correction in WO possible
8)
Value range for empirical mean value memory:
1 to 20 numbers (n) of the empirical value memory, see channel-specific SD55623 $SCS_MEA_EMPIRIC_VALUE[n-1]
10000 to 200000 numbers (n) of the mean value memory, see channel-specific SD55625
$SCS_MEA_AVERAGE_VALUE[n-1]
When measuring with spindle reversal, the radius/diameter of the probe must be precisely determined. This should be
9)
realized with a calibration variant of the CYCLE976 radius at the ring or at the edge or at the ball. Otherwise, the
measurement result will be falsified.
