Withstanding Voltage and Insulation Resistance Tests | Setting Test Conditions
Discharge when interlock is activated (Discharge Interlock)
This can be set only in DC withstanding voltage (DCW) and insulation resistance (IR) tests.
During a test, the EUT, test leads, test probes, and the area around the output terminals are all charged to
a high voltage. Set whether to discharge the voltage remaining in the high voltage charge area if the inter-
lock is activated (p.204) during a test.
1
On the Home menu screen, press Time > Discharge Interlock.
2
Turn the rotary knob to change the value.
This completes the setting.
Value Description
ON The voltage remaining in the high voltage charge area is discharged if the interlock is activated
during a test. Use this when you do not want the voltage to remain if the interlock is activated,
such as when a capacitive EUT is connected.
OFF The output’s high voltage relay is opened to shut off the output if the interlock is activated.
