The MTD 20KWe earth is a digital and automatic Earth Resistance Tester, that allows to measure Earth Resistance (three pole) and Ground Resistivity by the Wenner’s (four pole) method.
Built in Voltmeter for measurement of earth resistances of lightning conductors, pylons, substations, primary cabins, industrial and home installations.
Measurement of grounding resistances (with 3 terminals), soil resistivity (with 4 terminals) and spurious voltages present in the soil.
Equipment injects an electronically stabilized current in the soil and measures with high precision the voltage developed in the soil by means fo that current flowing through grounding diffusion resistance.
Equipment operates as a CA conventional voltmeter, making it possible to check the presence and to measure voltages generated by parasitic currents.
A sharp and intermittent audible signal indicates the abnormalities in the circuit.
Resistances: 0-20, 0-200, 0-2000 and 0-20kΩ, Voltages: 0-200V
Resistance Measurements: ±(2% of the measured value +1% of the maximum value of the selected range), Voltage Measurement: ±(2% of the measurement value +1% of end scale value)
0.01Ω in the resistance measurement, 0.1V in the voltage measurement
The output power is less than 0.5W and the output current is limited to less than 15mA (Peak to Peak)
