A comprehensive earth tester capable of conventional 3 and 4 pole measurement of the resistance of earth installations, and ground resistivity. It offers many advanced features, including selective earth testing and 'stake-less' earth testing.The stake-less method is able to measure the resistance of individual ground connections in multi grounded systems without the use of ground stakes; 2 clamps are clamped around the earth rod so leaving the bonded earth ground system intact during testing. Using this method, earth resistance tests can be conducted where there is on access to soil.

3- and 4-pole earth ground measurement 4-Pole soil resistivity testing 2-pole resistance measurement AC 2- and 4-pole resistance measurement DC Selective testing with no disconnection of ground conductor (using one clamp)Stake-less testing with no disconnection of ground conductor and no ground stakes for quick ground loop testing using 2 clampsResistance measurement without current or voltage spikes for rapid testing of pole mounted transformers.Earth impedance measurement at 55 Hz Automatic frequency control (94, 105, 111, 128 Hz) selects a measuring frequency to minimise the effect of existing interferenceSelectable test voltage20/48V enables safe testing where livestock may be present IP56 splash-proof caseProgrammable GO / NO-GO limits, settings Continuity with buzzer

2 test leads, 4 earth ground stakes, 3 cable reels with wire (2 x 25m, 1 x 50m), clamp set for selective / stake-less (one inducing, one sensing), batteries, manual, carrying case.
