Notes:
1.The battery and switch to commercial power are seamless handover ;
2.Battery charging mode: after power on, 10 seconds battery self test, prepare charging, constant-current charging, float charging after battery fully charged. It’s normal that the voltage fluctuate when battery is not loaded.

Notes:
Criterion A: Normal performance during and after test.
Criterion B: Low-voltage protection or reset is not allowed. Temporary output voltage fluctuation ceases after disturbances ceases, and from which the EUT recovers its normal performance automatically. During the system test, output voltage fluctuation or reset is not allowed too.
Criterion C: Temporary loss of output is allowed, but the hardware can’t be damaged. The EUT recovers its normal performance automatically or operator intervention.
Criterion R: Loss of output which is not recoverable is allowed. The primary protective component (fuse) can be damaged. The EUT recovers its normal performance after replace the damaged component.
