DR 22 Tolerance parameters
8.21.1
The tolerance limits that are to be used in a tolerance check by WP251 are defined in the
data record. Two tolerance bands are defined around the set point. The result of the
tolerance check is available in AWI Status.
The tolerance limits around the set point are as follows:
● TH 2
● TH 1
● SINGLE SET POINT (DS 20)
● TL 1
● TL 2
For example, if TH2 & TL2 are defined with 2 kg and TH1 & TL2 with 1 kg, a dosing will be
rated as "Good" (AWI Status) if the weight was dosed with an accuracy of +/- 1 kg around
the specified set point. If the final weight differs more than +/- 2 kg from the specified set
point, the tolerance check returns "Bad" (AWI Status).
The reaction of the scale to a tolerance error is also defined in DR 22.
