NOTE
• Discharging will stop if you press the STOP switch during forced discharge. How-
ever, discharging will not stop if the discharge time has been set to 0.0 s.
WARNING
• When you stop forced discharge, the voltage between the output terminals
may still be at a dangerous level.

WAIT
In insulation resistance testing, if a test voltage is applied to a DUT that contains
capacitive elements, the measured insulation resistance will be below the optimal
value due to a charge current, until charging is completed. To avoid upper fail judge-
ment by the charge current, a wait time must be provided from the starts of START
VOLTAGE, and upper fail judgement will be ignored during wait time.
Set the wait time to 0.3 s through 10 s (at a resolution of 0.1 s).
When the cursor is located to the right of WAIT, the rotary knob can be used to
make settings.

NOTE
• With the timer ON, if the wait time thus set exceeds the sum of the voltage rise
time and the test time, "OVER WAIT" flashes on the LCD to indicate that testing
cannot be performed.
