Description
Martindale ET4000 Multifunction Tester
Suitable for use with domestic, commercial and industrial wiring installations, the Martindale ET4000 Multifunction Tester is ideal for any professional electrical installer.
Designed to make installation testing as simple as possible, the ET4000 performs all necessary testing procedures, including insulation resistance at 50, 100, 250, 500 and 1000V, continuity testing at 200mA and 8.5mA, loop resistance and PFC (with dual display), auto RCD and ramp tests plus TRMS voltage, frequency and phase sequence.
Results are shown in two ways. A full test reading is displayed on the ET4000’s high quality backlit LCD screen, and dual LED indicators will illuminate with a red/green light for tests that FAIL/PASS.
The ET4000 also includes built-in new third amendment Zs loop impedance and help screens to guide users through every aspect of the testing process. When testing loop, this tester won’t trip the circuit and performs automatic polarity and wiring checks.
