Martindale Electrical Tester ET4
Martindale's ET4 is a multifunctional electrical testing device that enables any electrician to carry out measurements without the need to use multiple devices.
The ET4 can be used to test DC and AC voltage, DC and AC current, frequency, resistance, continuity and diode. It even includes a built-in non-contact voltage detector which gives indication of voltage presence from 70 to 600V.
An LCD screen in the front of the unit relays all test results. It can also display two values at once; it is possible to use the ET4 to measure either current/voltage or frequency/voltage at the same time.
In addition to its standard measurement functions the Martindale ET4 also includes autoranging test measurements, a data hold function and the ability to shut down automatically in order to conserve the battery life.
