8.21.2 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 Meaning
0 (default)
The tolerance limits are interpreted as percentages of the set point in DS 20
1 The tolerance limits are interpreted as absolute weight values
2 The tolerance limits are calculated based on OIML R61 "Limits of error on verifica-
tion Class X1".
3 The tolerance limits are calculated based on OIML R61 "Maximum permissible
errors in service Class X1".
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.
