3.8.2 Ending the test
PASS judgement
Example of an AC withstanding voltage test (PASS)
When the timer is ON:
When the test time has elapsed without the occurrence of the FAIL status, the test
ends with a PASS judgement.
When a PASS judgement is made, “PASS” appears at the top right of the LCD, the
PASS LED lights on the indicator, and a buzzer sounds. The PASS judgement is dis-
played for approximately 0.2 seconds (by default). The display time for the PASS
judgement can be set to 0.2 s through 10.0 s or to HOLD. The buzzer action syn-
chronizes with the PASS display time. For the setting procedure, see "3.10 System
Settings".
The measurement results are displayed while “PASS” is displayed.
When “PASS HOLD” is not set to “HOLD,” the tester automatically returns to the
READY status after a PASS judgement is made.
When the timer is OFF:
The test continues until the FAIL conditions are met.
Press the STOP switch to suspend the test. The test does not make a judgement and
“PASS” is not displayed.
