7.2.2 Leakage Current Measurement
Electric current is measured with the test voltage generated,
as in insulation resistance measurement.
Measuring range: 1.00 nA to 1.20 mA
• Auto range
• Temperature and humidity range for guaranteed accu-
racy: 0°C to 28°C less than 80% RH (no condensation)
Temperature
characteristics
Measurement accuracy × 1 is added to
the accuracy.
When the 9750-11, 9750-12 TEST LEAD
(10 m) is used, a resistance of 501 G or
more is not guaranteed.
(with an ambient temperature outside the
range of 0°C to 28°C)
Response time
Within 15 sec. (This is the period of time
after measurement has started until the
displayed value falls within the specified
accuracy range, when averaging is not
used.)
* When a value below the lower limit of each range is displayed, the
accuracy is not guaranteed
