Socket Tester RCD GFCI NCV Test Outlet Tester Voltage Tester EU US UK Plug Ground Zero Line 30mA Smart Socket Detector 30-250V
Note: Our product requires the installation of batteries. Please use it after installing the batteries.
Description:
-The polarity detection of the three hole power socket wiring
-The protection function detection of the leakage switch
-It can quickly and accurately detect the wiring
-Widely used:fire protection/laboratory/factory/family
¢ºVoltage measurement
1. The normal voltage range of 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.
¢ºRCD 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.
¢ºSix Test status analysis show
1.Wire is corect
2.Missing zeo line
3.Missing ground
4.Fire gound reserse
5.Fire zero reserse
6.Mismatch and lack of land
