How does the Socket & See SOK50 Work?
Using the Socket & See SOK50 is simple. Insert the tester into a 110V industrial socket and switch on the supply. The tester immediately performs an automatic self-check, indicated by flashing red and green LEDs. During this period, no measurement takes place.
Once the self-check has finished, the Socket & See SOK50 provides both LED and audible indications. A continuous tone confirms the correct wiring sequence, while a strong warbling tone indicates an incorrect condition. The indication table on the tester can then be used to identify the wiring sequence or fault condition.
