The upgraded version of Martindale's ET4000 multifunction tester, the ET4500 is a fully downloadable installation tester.

With built-in loop Zs tables based on amendment 3, several advanced measurement modes, high accuracy technology and a number of additional useful features, this multifunction tester is ideal for use on domestic, commercial and industrial electrical installations.

The built-in memory of the ET4500 allows users to easily document testing data without jotting everything down. Via a simple USB connection with PC, this information can also be directly downloaded into Martindale's included ET-Link software* for further analysis.

A comprehensive suite of testing procedures is included in the Martindale ET4500. It can perform insulation resistance testing at 50, 100, 250, 500 and 1000V, continuity testing at 200mA and 8.5mA, loop resistance and PFC with dual display, TRMS voltage, frequency and phase sequence testing and - via the use of an optional earth testing kit (code ER2KIT/S) - can perform three wire earth resistance testing.

Test results are shown in two ways. The first is a full reading on the built-in graphical LCD display, while the second is a dual LED indicator that shines with a red light for fail and a green light for a pass.

Good quality tester

Review by James burke (Posted on 22/05/2017)


Good tester, has helpful menus for which leads are required, bit slow at zeroing out the leads, but the zs no trip is fairly quick. Brilliant tester if you haven't a lot of experience and easy to use, worked out without the manual. Not as good as a megger. Probably on par with a fluke for usability
