About The Martindale ET4500 Multifunction Tester

Made for domestic, commercial and industrial wiring installations, the Martindale ET4500 is an advanced, downloadable multifunction tester.

Featuring built-in amendment 3 fuse tables and green/red PASS/FAIL indicators, the ET4500 helps professionals installers to speed up testing thanks to quick and easy indication of the test's results. In fact it's built from the ground up for simplicity, with the ability to simultaneously display all RCD testing results on one screen, simple rotary dial test selection, pass limit adjustments and even integrated help menus for connection reminders.

The ET4500 can perform every test necessary to verify installations including continuity tests at 200mA and 8.5mA, insulation tests at 50, 100, 250, 500 and 1000V, RCD tests on AC, A, F and S type RCDs with trip time, auto and ramp tests and includes additional testing such as non-trip earth loop, high current loop, 3-wire earth resistance, true RMS voltage, frequency and phase rotation.

Using the included software, it's possible to both download testing data from the instrument and also upload information relating to the site you're working on for faster testing. Downloading and uploading is simple - just connect up a USB lead from the tester into your PC.

You won't even have to worry about replacing the batteries with the ET4500 - it comes supplied as standard with rechargeable ones.
