The earth tester / earth resistance meter is a versatile ohmmeter. With this grounding meter a variety of resistance measurements can be performed. Thus, with the grounding meter, the possibility exists to perform a normal resistance measurement of 2- or 4-pole application. It is also possible to determine the resistance of the soil with the grounding meter. For the measurement of earth resistance corresponding earth spikes are included in the scope of supply. These ground spikes can easily be connected to the grounding device via the supplied separate 20 meter / 66 ft cable.
Another important measuring function is the measurement of the resistance of, for example, lightning conductors. This measurement is used to control the lightning conductors on, for example, schools or university buildings and is essential to derive a possible lightning strike into the ground. This earth tester / earth resistance meter can thus be used to determine whether the lightning rod is properly connected to the ground and whether it has the right resistance value to discharge a lightning bolt into the ground.
To ensure a perfect measurement, the earth tester / earth resistance meter has a measuring terminal detection. After the operator has set the grounding meter to the desired measurement function, the terminals to be used light up. If an incorrect connection has been selected by the operator, the grounding meter signals the operator both acoustically and visually. At the same time, the measurement by the grounding meter is refused until the test setup has been properly connected. This massively limits faulty measurements by the intelligent grounding meter. Also, the grounding device has a memory. This allows the measurement data from the grounding meter to be transferred to a PC and evaluated after a measurement.
