Input resistance 1 MΩ ± 1 %
Input capacitance
200 pF or less
(internal voltmeter input capacitance: 100 pF
or less)
Common mode rejection ratio
10 kHz or less: 60 dB or more, 10 kHz to 1 MHz: 40 dB or more
Offset cancel function Cancels up to 10 mA of the unnecessary current from
measurements. OFF function available.
1 Voltmeter band expansion is possible when network I is selected.
2 When zero adjustment has been performed using the offset function. In current measurements, especially when the
measurement mode is set to Peak or when network A is selected, current measurements may not be stable due to the
effects of the power supply line waveform or the wiring environment between the product and the EUT.
3 0.1 Hz ≤ f < 15 Hz is for when voltmeter band expansion (VoltMeter BandWidth) is set to Expand. Requires at least
120
second of test time.

A value conv
erted to current for measurements using Network A, B,
C or H
with voltmeter accuracy of this product as the
reference.
If a network other than A, B, C or H is used, calculate as follows:
For Network D, E, or I, the ■ pa
rt of ±( □ % of reading + ■ A) is half the value.
For F, the ■ pa
rt is one-third the value.
For G, the ■ p
art is one-fourth the value.
For PCC-1 or PCC-2, the ■ pa
rt is 3.3 times the value.
