: Indicated value at each insulation resistance
range comes within accuracy within 5 sec. after
a resistance corresponding to the mid-value
and 0 is suddenly applied across the
Ω
measuring terminals. (It may take time when
measuring a capacitive load.)
: AC5,320V(50/60Hz) for 5s. between the
electrical circuit and the enclosure．
: The instrument operates properly after each of
the voltage shown in the table below is applied
for 10 sec.
