Testing Function  
(1) Stable-state Test: load power in rated range, measure generator steady-state 3 phase voltage, current, active power, reactive power, apparent power, power factor, frequency, and running time.
(2) One-key load/unload: no mattery using software control or manual control, can set loading power first, then press master load switch, this avoid the load fluctuation.
(3) Setting Test: can catch the max and min setting value of voltage and frequency, and calculate the relative setting up and down range of voltage and frequency and adjustment rate within 100 seconds setting time.
(4) Fluctuation Test: catch the max and min fluctuating value of voltage and frequency, and calculate steady-state frequency band, steady-state voltage deviation, voltage modulation, fluctuation rate and frequency in 60 seconds fluctuation time.
(5) Transient Test (Instant Load Test): sample interval is 40μs,system catch the transient max and min value and recovery time of voltage, current, and frequency, and calculate instant load transient voltage deviation and instant load transient frequency deviation.
(6) Transient Test (Instant Unload Test): sample interval is 40μs,system catch the transient max and min value and recovery time of voltage, current and frequency,  and calculate instant unload transient voltage deviation and instant unload transient frequency deviation.
(7) Harmonic Analysis: It can analysis 2~50 harmonic content and total harmonic content in voltage and current at same time.
(8) Record Wave Analysis: 5 patterns for recording voltage real-time waveform, and the record time is 4~ 280 seconds and accurately sampling at 128 points in a wave cycle at most.
