This digital earth resistance tester is used to measure earth resistances of various electrical devices. To determine the resistance of the grounding, the device applies a voltage of 200 V to the line being tested. Furthermore, with the PeakTech 2700 deep earth electrode, measurements and checks can be performed using the auxiliary earth spikes included in the delivery. The testing device not only has the function of measuring earth resistance, but it is also capable of measuring direct and alternating voltages as well as resistances. With the PeakTech 2700, every electrical installer is optimally equipped for the inspection of grounding systems, deep earth electrodes, and standard measurements.
