Parameter relation

The parameters are used to define how the specified tolerance limits TH2, TH1, TL1 and
TL2 are to be interpreted. The following options are available:
Function code
0 (default)
1
2
3
In general, the currently valid tolerance limits in data record 31 are output in the weight unit.
When function codes 2 and 3 are selected, the entered tolerance limits TH2, TH1, TL1 and
TL2 are ignored because the limits are calculated automatically based on the OIML
Recommendation.
