11.2.
Setpoint Comparison
This function includes the weighing sequence and uses for acquiring a preset
target weight.
There are four parameters of "Final", "Preliminary", "Free fall" and "Zero band" to
use the setpoint comparison.
The result of the sequence is output to three relays of OP-03, OP-05 or OP-08.
It is not necessary to enter the F-function F22 again unless comparison
conditions will be changed.
11.2.1. Description of Input Parameters and Outputs
F22 = 7 (Check weighing 1)
Output and Condition

OVER/UNDER is judged always and the result is output to the display and the relay.
F22 = 8 (Check weighing 2)
Output and Condition
