| Range switching | Auto or Fix selectable. If a measurement falls outside the measurement range of each range, the measured value blinks as a warning. | |||
| Auto | The range is set automatically according to the measurements. | |||
| Fix | For 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. | |||

*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.
