Pre-acts 1 and 2 are always available as subsets of their respective targets from the Weigh Mode.
Since the discharge portion of the Both cycle is a loss-in-weight operation, target 2 and pre-act 2 entries are entered as
positive values and interpreted by the indicator as negative. See Changing Targets from the Weigh Mode (General) on
page 65 for detailed instructions on changing target values from the Weigh Mode.

Independent Setpoint Operation
Independent Setpoints allow controlling setpoints when the gross, net or quantity (if counting is enabled) is above or
below a target value. The reset (deactivation) choice of each setpoint is selectable from Tare, Remote Key, Auto, Non-
latching or Absolute. See Key-In Parameters on page 43 for instructions on using front panel keys for data entry.
