[F1] Clamp meter terminal or clamp meter input selection in the state of main screen. In the condition of harmonic analysis and waveform, view A phase harmonic or wave shape;
[F2] Automatically match the number of laps when checking errors in the state of main screen. In the condition of harmonic analysis and waveform, view B phase voltage harmonic or wave shape.
[F3] Commonly used constant choice in the state of main screen; in the condition of harmonic
analysis and waveform, view C phase voltage and current harmonic, and wave shape.
[F4] The main screen calibration record delete key and power supply mode switch function key. (F5] Suspend the interface jumping, and save when the main screen shows error checking.
[0] Automatic matching and testing of the energy meter's not constant.
