*35: The accuracy values are in the case that the output voltage is within voltage setting range, values
for power factor 1 in DP series, and values for power factor 1 in DP series Type R. In the
polyphase model, polyphase system, and polyphase output of the Multi-phase, this specification
is for the phase voltage and the DC average value display cannot be selected.
*36: The accuracy of the peak value is for a waveform of DC or sine wave.
Voltage (Line voltage. Only with the polyphase model, polyphase system, and polyphase output of
the Multi-phase model. Only with sine waveform output.)

*37
*37: The displayed value is the result of calculation with the phase voltage measured value and the
phase angle setting value regarding the output voltage waveform as a sine wave.
