*23: The accuracy values are in the case that the output voltage is within voltage setting range. For the
polyphase system, this specification is for the phase voltage and the DC average value display
cannot be selected.
*24: The accuracy of the peak value is for a waveform of DC or sine wave.
Voltage (Line voltage of polyphase system, only with sine waveform output.)

*25
*25: 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.
