Precautions for the use of socket detectors
1. Please operate the socket tester correctly when using it, and use it under the conditions limited by the technical parameter table.
2. When the socket under test has a power indicator, "missing neutral wire" and "reverse connection between phase wire and ground wire", the LED lights are displayed as:
3. Before testing the leakage protection system, please turn off the electrical appliances and confirm that the power failure will not cause any harm.
Fourth, do not damage the instrument insert, so as not to affect the test results.
5. When using, please do not touch the metal insert of the instrument to avoid electric shock.
6. When the test result is "correct connection", it can only indicate that the phase wiring of the socket is correct. Only by passing the "RCD test" can it be shown that the grounding resistance of the tested socket meets the specification design requirements, and the leakage protection system is safe and effective.
7. Electric leakage detection is strictly prohibited in public places without permission.
Eight, unauthorized disassembly is prohibited.
9. Strictly prevent strong electricity and electrostatic shock.
The above contents are some of the things that should be paid attention to when using the YW-331 socket tester. Users who want to know more about the quality inspection quantity and instrument industry information can pay more attention to the follow-up updates of "Yuwen Measurement"~
