Pass/fail judgement Type of • Window comparator type
judgement • If the current detected is larger than the preset upper cutoff
current, the Tester gives a FAIL judgement.
• If the current detected is less than the preset lower cutoff
current, the Tester gives a FAIL judgement.
• As the Tester gives a FAIL judgement, it cuts off the
output and delivers a FAIL signal.
• If the test period elapses without any unacceptable condi-
tions, the Tester gives a PASS judgement.
Upper cutoff 0.1 to 55mA AC 0.1 to 110mA AC
current setting 0.1 to 5.5mA DC 0.1 to 11mA DC
range
Lower cutoff 0.1 to 55mA AC 0.1 to 110mA AC
current setting 0.1 to 5.5mA DC 0.1 to 11mA DC

accuracy
Current detection The absolute value of current is integrated and compared
with the preset cutoff current value.
Calibration Calibrated for r.m.s. value of sine wave, with pure-resistive
load
No-load output Approx. 970V when Approx. 460V when
voltage required at 50mA AC setting at 100mA AC setting
for detection Approx. 160V when Approx. 100V when
(Note 6) at 5mA DC setting at 10mA DC setting
Test time Setting range 0.5 to 999 s. (with Timer-off function)
Accuracy
±
20 ms
Note 5: When in the AC mode, the current which flows through the stray capacitances of the test
leadwires, test jigs, and other items on the test circuit also causes measuring errors. The total
judgement accuracy is the sum of this current and the above-mentioned judgement accuracy.
Approximate values of such currents are shown in the following table. Note that, in high-
sensitivity high-voltage test, the current which flows through the stray capacitances may
become larger than the preset lower cutoff current and the LOWER PASS/FAIL judgement
may not be successfully done.

When other test leadwires than the above are used, the current may differ depending on the
conditions of use.
Note 6: In order to be able to make a FAIL judgement when in the state that the output terminals are
shorted, a certain minimal level of no-load output voltage is necessary due to the internal
resistance of the output circuit. This item indicates such minimal output voltage.
