NAME FUNCTION
1 HIPOT
When ON, Dielectric breakdown detect will be activated.
When in DEFEAT position, test will continue regardless of a dielectric breakdown, but it can be stopped by the excess
leakage limit. NOTE: The RAMP switch, and TIMER switch must also be in the DEFEAT position, otherwise the buzzer
will sound. The test will continue only as long as the TEST button is pressed. Minimum test time is approximately one
second.
2 TIMER
When ON, test duration is set by TIMER ADJUST, Item 5.
When in DEFEAT position, testing continues only as long at TEST button is pressed. Minimum test time is one second.
NOTE: TIMER Switch position must be DEFEAT when HIPOT Switch is in the DEFEAT position.
3 RAMP
When ON, Voltage ramp up time is controlled by RAMP ADJUST potentiometer, Item 6.
When in DEFEAT position, high voltage is applied immediately when TEST button is pressed. NOTE: RAMP switch
position must be DEFEAT when HIPOT switch is in the DEFEAT position.
4 LEAKAGE ADJUST

5 TIMER ADJUST Adjusts the test duration. For details see “Test Time Adjust”.
6 RAMP ADJUST
Adjusts the delay between time TEST button is pushed and time desired output voltage is attained. For details see
