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.
