The ET4 is a very compact electrical tester that measures AC/DC voltage, resistance and AC/DC current. Continuity with a buzzer is also included.
It can also measure frequency and continuity and will take simultaneous measurement of current/voltage and frequency/voltage by employing the open jaw clamp and test probes simultaneously.
This electrical tester can be used as a non-contact voltage indicator using the inbuilt sensor in the left tip of the open jaw clamp and has auto-ranging, display hold and auto power-off functions.
The right tip of the jaw has a forward-facing LED light to illuminate the local working area.
The ET4 is supplied with TL17 test leads, a soft carry case with belt loop, 9V battery and manual.
