There are two different ways to carry out evaluation of limits:
1. Evaluation of absolute values [
24. TXP.1
] :
An exact reference value (e.g. 1 kg) is set.
2. Evaluation with difference values
[
24. TXP.2
] :
An upper limit and a lower limit for a reference value are set.
Example:
Reference value Lower limit Upper limit
Poured quantity 1,000.0 g 970.0 g 1,050.0 g
Evaluation of absolute
values
1,000.0 g 970.0 g 1,050.0 g

ence values
1,000.0 g -30.0 g 50.0 g
