Description
The MTD2000B digital earth tester allows for the measurement of Earth Resistances and Soil Resistivity, and also the spurious voltages caused by parasitic voltages present in the soil. This equipment is suitable for fast and easy measurement of the grounding resistance in house and industrial buildings, hospital installations, lightning rods, antennas, substations, etc. Soil resistivity measurement allows for soil stratification in order to optimize the most complex grounding systems.
Its state-of-the-art system of active and passive filters provides it with high immunity to electric interferences, making it possible to obtain reliable measurements even in the presence of spurious voltages, such as the ones that can be found in some urban areas and near primary substations.
A 1,470 Hz internal generator injects alternated current on the soil through an auxiliary rod. The voltage generated over the earth resistance is measured by the apparatus, and the resistance value is evaluated. The test current is automatically limited.
This earth tester is supplied with a rechargeable internal battery. The smart charger is microprocessor-controlled, and can be powered from the 100 - 240 V mains adapter or from a 12 V automobile auxiliary power outlet.
