Trip point and Hysteresis
When entering the values for the trip point and hysteresis, please observe the following:
By means of the Gross/Net parameter, you determine whether the value for the trip point is a gross
value or a net value (gross value minus current tare).
The trip point and hysteresis must be entered in the selected unit.
The minimum value for the trip point is 0, the minimum value for the hysteresis is 0.1.
If you have selected Gross, the maximum ce ll load is the maximum value for
the trip point and hysteresis.
If you have selected Net, the value of the maximum cell load minus the current tare
is the maximum value for the trip point and hysteresis.
