Watch: Martindale Socket Testers

Dave Austin explains how to choose between the Martindale Buzz-IT, E-Ze Check and E-Ze Test socket testers for identifying wiring faults to measuring earth loop impedance.

With the audible indication, the Buzz-It can also be used as a basic fuse finder, when the correct fuse is pulled the buzzer stops. Meanwhile, the EZ150 is the first socket tester that checks the wiring of 13A sockets and also gives a measurement of the earth loop impedance.
