[after the offset cancel function is activated, if the scanner is mounted]
Response Mean-value responsive / root-mean-square value display (response time of 200 ms)
Hold function The measured current at the end of the test is held during the PASS period.
Offset cancel function The current fl owing to the insulation resistor between the output cables and the stray
capacity is cancelled up to 100
μ
A/kV (in AC withstanding voltage testing only).
Calibration Performs calibration using the root-mean-square value of a sine wave with a pure
resistive load
Selection of LOW/GUARD
for the GND (*4) Selection permitted for current measurement between the mode for the GND point
connected to the LOW terminal, and the mode using guard.
LOW Connects the GND point to the LOW terminal. Measures the current fl owing to the
LOW terminal (chassis) (for normal operation).
GUARD Sets the GND point as guard. Measures the current fl owing to the LOW terminal,
but does not measure the current fl owing to the chassis (for high-sensitivity, high-
accuracy measurements).
