GOOD/NO-GO Judgment Function

Judgment System
•
Window comparator
•
A NO-GO judgment is made when a current greater than
the high limit value or smaller than the low limit value is
detected.
•
When a NO-GO judgment is made, the output voltage is
cut out and a NO-GO alarm signal is delivered.
•
If no abnormal state is detected during the test time a
GOOD Judgment is made and a GOOD signal is
delivered.
