Comparator Function - A&D GX-203A Instruction Manual

10-5 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 HI
display.
When 5-step comparator is set, HH is indicated by HI blinking and LL by LO blinking.
By using GXA-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.
"Digital input" and "Input by sample load" are the for each value input methods for each value.
