1. Standby Interface

After power on, the digital tube will display current grid voltage and load current, e.g.: 220V 63.0A.

2. Enter Setting Mode

Press and hold the SET button for 3 seconds to enter parameter setting mode. The digital tube displays the first parameter code, e.g. P-1.

3. Select Parameter

Press ▲ or ▼ buttons to browse parameters. Find the parameter to set, e.g. P-3 (overvoltage protection point).

4. Adjust Value

Press SET button again to enter value adjustment. Use ▲ or ▼ to modify the value. Press and hold SET to save and move to next parameter.
