The Martindale ET4 is a compact electrical tester that measures AC voltage, DC voltage, AC current, DC current, resistance, frequency and continuity and can take simultaneous measurements of current/voltage and frequency/voltage.

The electrical tester can be used as a non-contact voltage indicator and features auto-ranging, display hold and auto power-off functions.A forward-facing LED illuminates the area in front of the forks, making it ideal for use in poorly lit spaces.
