10.2. Setpoint Comparison

This function includes the weighing sequence and is used for acquiring a preset target weight.

There are four parameters of "Final", "Preliminary", "Free fall" and "Zero band" that use the setpoint comparison.

The result of the sequence is output to the three relays of OP-03, Op-05 or OP-08. When entering these parameters, it is not necessary to enter the F-function f22 again unless comparison conditions are changed.
