Giant display socket tester
-The polarity detection of the three gap energy socket wiring
-The safety operate detection of the leakage change
-It may shortly and precisely detect the wiring
1. The traditional voltage vary of zero hearth line is plus or minus 10% of the native commonplace voltage. Whether it is too excessive or too low, it might be as a result of the circuit load is just too excessive or the ability provide is just too low/ too excessive.
2.The traditional voltage of zero-earth wire is lower than 2V, if too excessive possibly it’s as a result of there’s present leakage, or the three phase-sequence is out of steadiness or there’s sign interference within the circuit.
Please flip off all electrical home equipment earlier than utilizing this operate,and accomplish that with permission to make sure that the ability outage won’t trigger any hurt.
