A&D Weighing Indicator AD-4329 - Manual (Page 38)

9. Comparison
□ This function has the "upper / lower comparison" and the "setpoint comparison". They
compare the weighing data with preset parameters and can output the result of the
comparison to the reiay-outputs of OP-02.
□ Set the F-function the/^*¿'0 and /to use these comparisons.
Caution □ The result can only be output using relay-outputs, and is not displayed.
□ The setpoint comparison can be used for normal batching, but can not
be used for loss-in-weight.
9.1. Comparator Output Relay (OP-02)
□ This relay option outputs the result of comparison controled by the F-function f~^0
(comparator function) and / (comparator mode).

9.2. Upper/Lower Limit Comparison
This function compares the weighing data with the upper limit value and lower limit
value, and outputs the result to the three relays of HI, OK and LO. Use this comparison
when judging whether a weight is proper.
Set to the F-function f~EQ I to use this upper/ lower limit comparison.
Select a parameter of the F-function I for the comphson condition.
Specify the upper and lower limit values.
When inputting the upper value and lower limit value, it is not necessary to input the F-
function f ~ BQ and f 1 again unless changing the F-function,
