Range3DC, RMS: 125.0 μA(min.) to 20.000 mA(max), Peak: 175.0 μA(min.) to 28.300 mA(max)
Range4DC, RMS: 1.250 mA(min.) to 100.00 mA(max), Peak: 1.750 mA(min.) to 100.00 mA(max)
Range switchingAuto or Fix selectable. If a measurement falls outside the measurement range of each range, the measured value blinks as a warning.
AutoThe range is set automatically according to the measurements.
FixFor TC and PCC measurements, the measurement range is selected automatically according to the UPPER value. For meter measurements, the range is fixed to the specified range.
Bandwidth switchingCan be expanded to a bandwidth that allows measurements from 0.1 Hz, which is required in the measurement of medical instruments and the like.
NormalNormal measurement bandwidth: 15 Hz to 1 MHz
ExpandExpands the measurement range to 0.1 Hz to 1 MHz

*1 Voltmeter band expansion is possible when network I is selected. *2 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. *3 A value converted 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 ■ part of ±(□% of reading + ■A) is half the value.
For F, the ■ part is one-third the value.
For G, the ■ part is one-fourth the value.
For PCC-1 or PCC-2, the ■ part is 3.3 times the value.
