> to change voltage between P1 and P0, P2 and P0, P3 and P0.
*Before start measuring, select phase and wire system according to the measured load.
When Single-phase 3-wire or Three-phase 3-wire is selected, it doesn’t measure Single-phase
2-wire system correctly. When Three-phase 4-wire system is selected, it doesn’t measure
Single-phase 2-wire, Single-phase 3-wire, Three-phase 3-wire system correctly.
Select phase and wire system according to the measured system.
(Refer to the explanation of setting mode.)

・
When input voltage is under 10.0V at 200V range, and when input voltage is under 20.0V at 400V
range, it displays “0.0” and doesn’t measure.
・
When input voltage exceeds 150%F.S. at each range,
