The ET4 is a very compact electrical tester that measures AC/DC voltage, resistance, AC/DC current, frequency and continuity. Continuity with a buzzer is also included.
The tester can take simultaneous measurements of current / voltage and frequency / voltage by employing the open jaw clamp and test probes simultaneously. It can also be used as a non-contact voltage indicator using the built-in sensor and has auto-ranging, display hold and auto power-off functions.
The jaw features a forward-facing LED light to illuminate the local working area.
