Features
- The bench can be used to test both single / three phase active and reactive energy meters (up to 0.2 class), and it is also suitable for four quadrant test.
- The signal source can repeatedly add 2 - 21 harmonics on the first sine wave, or cause sub-harmonic wave and odd sub-harmonic wave.
