The PCE-ERT 10 is a handy measuring instrument, which allows fast and easy determination of the earth resistance. The earthing device determines the earth resistance with three-wire technology in three measuring ranges up to 2000 Ω. By means of a rotary knob, a zero position can be performed before each measurement in order to achieve the optimum accuracy. Furthermore, this grounding measuring device offers a normal resistance measurement up to 200 kΩ, the measurement of the ground voltage, and a voltage measurement for DC and AC voltage.
