● If 0.03 mm is exceeded (_TUL/_TLL), the radius in T20 D1 is compensated 100% by this
● If 0.02 mm (_TMV) is exceeded, the radius in T20 D1 is compensated 100% by this
● If it is less than 0.02 mm (_TMV), the mean value is calculated from the mean value in
The results are entered in result array _OVR[ ].

mean value memory _MV[19] and inclusion of weighting factor _K=3 (only for
_CHBIT[4]=1! with mean value memory).
– - If the mean value obtained is >0.01 (_TZL), the reduced compensation of the radius
for T20 D1 is the mean value/2 and the mean value is deleted in _MV[19].
– If the mean value is < 0.01 (_TZL), the radius value in T20 D1 is not corrected, but if
the mean value memory is active (_CHBIT[4]=1), it is saved in the mean value
memory _MV[19].
