Comparator Function - A&D GX-M Series Instruction Manual

11-8 Comparator Function

The comparison of comparators can select 3-steps or 5-steps (Cp fnc, Cp-t), and it is set to 3-steps at the
factory setting.
When 3-step comparator is set, the results of the comparison are indicated by
the display.
When 5-step comparator is set, HH is indicated by
By using GXM-04, it is possible to output the comparison result at the contact point.
There are three types of scope that can be selected as follows.
 No comparison
 Comparison when the weight data is stable or overloaded
 Continuous comparison
The conditions for comparing near zero are in six levels from "including near zero" to "± 100 digits".
"Upper limit value and lower limit value" and "reference value and tolerance range" are the
comparison standards.
There are "Digital input" and "Input by sample load" as input method for each value.
Refer to the function setting

Note
□ The comparator function in the flow measurement mode (ApF3) is compared at the factory
setting with the flow rate value. By setting CP-Frd of the Function table CPFnc to "1", it is also
possible to compare with weight value (g unit).
