Tekneka’s TK20 socket tester is used to check the current polarity and safety of leakage current sockets. It can display the voltage connections of the test sockets and accurately determine if they are wired correctly. To detect safety trips and ensure the system can respond quickly in the event of an electrical accident, the TK20 has an RCD test function.
By displaying a sensitive level and sounding an alarm, the built-in non-contact voltage (NCV) tester enables voltage detection. Incorrect polarity, wiring in the wrong direction, the status of the live wire, and missing wiring are indicated on the display LED.
