Hold function The resistance measurement after a test is finished is held
while the pass judgment is displayed.
Offset cancel function Cancels up to 2 000 GΩ of the unnecessary insulation
resistance across output cables and the like. OFF function
available.
1 Humidity: 70 %rh or less (no condensation), when there is no interference caused by wobbly test leads or other
problems.
