Setpoint Comparison
This function includes the weighing sequence and is uses 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.
