10Distortion degree of output voltage and current waveform:0.5%The distortion of the current waveform shall not exceed1%
11The harmonic of the device can be set simultaneously for voltage and current, as well as for phase separation. Any phase output can contain multiple harmonic components.
12The monitoring values of voltage, current, power, power factor, phase, frequency, etc. of this device are all taken from the indications of the multifunctional standard meter, standard table
The level shall not be lower than the level of the device, Therefore, there is no need to separately verify the monitoring table. The set value of the output power can be compared with the measured value of the standard meter
The difference between them is considered as the error of the monitoring instrument.
