<Number of measurement >
Possible number of measurement within the "BATTERY.GOOD"
range.
(Measure 5 sec., and take pause for 25 sec.)
Temperature : 0℃∼40℃ (RH: 90% or less)
&
humidity range : (no condensation)
Storage temperature : -20℃∼60℃ (RH: 75% or less)
&
humidity range : (no condensation)
Response time : Indicated value at each insulation resistance
range comes within accuracy within 5 sec. after
a resistance corresponding to the mid-value
and 0 Ω is suddenly applied across the
measuring terminals. (It may take time when
measuring a capacitive load.)
Withstand voltage : AC5,320V(50/60Hz) for 5s. between the
electrical circuit and the enclosure．
Overload protection : The instrument operates properly after each of
the voltage shown in the table below is applied
for 10 sec.
