The 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.

 

During the measurement of the earth resistance, the battery voltage is displayed next to the measured value in the large LCD display with background lighting. This special function of the earthing device helps the measuring technician to recognize the charging status of the batteries directly from the earthing device. In addition to the earthing device and the necessary measuring cables, the earth spikes are also included in the delivery. The set is completed by a carrying case, in which all the accessories of the earthing device can be found and can therefore be taken everywhere.
