The MEGGER DET5/4D and DET5/4R series Earth Testers are fully automatic, four terminal instruments built into a rugged, water resistant case giving protection for outdoor use. The instrument is suitable for the testing of earth electrodes and measuring earth resistivity. Operation is started by pushing one of two buttons on the front panel; one for three terminal measurement and one for four terminal testing.
All other functions of the instrument are completely automatic. The measurements from 10 m??to 20 k?.

The earth resistance reading is displayed quickly, accurately and directly on a large, clear 31/2 digit liquid crystal display. The display indicates when there is a high test spike resistance and also when the noise interference is too high to take a valid reading. If the batteries need replacing or recharging this will also be shown on the display.
Each Megger DET5 Earth Tester is built into a small, lightweight case with a handle that has been designed for outdoor use and has IP54 protection. Four large terminals allow either spade or hook connectors, 4 mm plugs or bare ended wire to be used for the test leads. The DET5/4D and DET5/4R digital earth testers are reliable instruments able to measure the earth resistance of both simple and complex electrode systems.
