(1) RG means range, the same as below; (2) RD means the setted harmonic content, harmonic can be a single output, also multiple output.

Features：

1. Able to test basic error, shunt running, start, standard error automatically and manually in single-step of single phase, according to relative regulation of energy meter.

2. Able to do change test caused by voltage inﬂuence, frequency inﬂuence and harmonic inﬂuence.

3. Output of power source is speedy and stable, AC current output can reach 120A in maximum. Voltage, current and phase angle can be adjusted in improving the ﬂexibility of power source.

4. Frequency of each impulse input port can reach 40Hz.

5. 7-inch TFT color display touch screen, English menu, simple and convenient operation, commonly used functions and current basic load point can be controlled in one button.

6. As 0.05% single phase power source, output 2-51 harmonics.

7. Impulse port of each meter position, external polarity can be set randomly, able to adapt kWh meter of impulse cascade and common-anode.
