Voltage measurement
1. The normal voltage range of a zero fire line is plus or minus 10% of the local standard voltage. If it is too high or too low, it may be because the circuit load is too high or the power supply is too low/ too high.
2. The normal voltage of zero-earth wire is less than 2V, if too high maybe it is because there is current leakage, or the three phase-sequence is out of balance or there is signal interference in the circuit.

RCD TEST
Please turn off all electrical appliances before using this function, and do so with permission to ensure that the power outage will not cause any harm.
