 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.
