ST05 socket tester is a device specially used to detect whether a socket is working properly. It can detect the voltage, current, resistance and other parameters of the socket to determine whether the socket is normal. The socket tester usually consists of a power supply part, a measuring part, and a display part. It is simple to operate and easy to use.
Functions:
1) Polarity detection of socket wiring and protection function detection of leakage switch;
2) Protection function detection of leakage switch;
3) Can quickly and accurately detect the wiring condition of the socket.
Feature:
1) Plug and test, digital display voltage;
Special attention:
① The normal range of fire and zero voltage is between 198~242V. If the voltage is too high or too low, it may be that the circuit load is large or the supply voltage itself is too high or too low.
② The neutral voltage is generally less than 2V. If the voltage is too high, there may be a leakage current in the circuit, a three-phase power imbalance, or an interference signal in the circuit.
2) Leakage switch protection detection;
Warning: Please turn off all electrical appliances before using this function, and ensure that power failure will not cause any harm with permission.
Plug the tester into a three-hole socket, and press the RCD button (press for less than 3 seconds) when the display prompts “Correct wiring.” At this time, the normal leakage switch will trip. If it does not trip, it means that the leakage switch has been lost or missing. Please find a professional electrician for repair in time.
3) Large color digital display screen;
A high-definition display lets you see the screen values clearly in a dark environment.
