To avoid possible electric shock or personal injury, please pay attention before using our professional socket tester:
Before use, please check the tester carefully to confirm whether it is damaged. If there is damage, please stop using it immediately and send it for repair.
To check whether the tester is correct, please insert the tester into a known correct socket for testing, and then use it after checking that the test function is correct.
The leakage switch test can be used normally only when the wiring is correct.
When detecting the leakage switch, please turn off the equipment on the electrical line to ensure that the power failure will not cause any harm. When testing in public places, the test must be approved.
