• 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.

Setting the WAIT TIME
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
V
OLTAGE, 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.
