Application: Measurement of grounding resistances (3 terminals), soil resistivity (4 terminals) and spurious voltages present in the soil.
Resistance measurement method: The equipment injects an electronically stabilised current in the soil, and measures, with high precision, the voltage developed in the soil by means of that current flowing through grounding diffusion resistances. Display shows the Resistance value.
Operation as a voltmeter: In the voltmeter function, the equipment operates as a AC conventional voltmeter, making it possible to check the presence and to measure voltages generated by parasitic currents.
Measurement ranges:
Resistance: 0-20 Ω; 0-200 Ω; 0-2000 Ω y 0-20 kΩ.
Voltage: 0- 200 V~.
Accuracy:
Resistance and Resistivity measurements: ± (2% of the measured value + 1% of the maximum value of the selected range).
Voltage measurement: ± (2% of the measured value + 1% of end of scale value).
Reading resolution: 0.01 Ω in the resistance measurement; 0.1 V in the voltage measurement.
Output power and current: The output power is less than 0.5 W, and the output current is limited to less than 15 mA (Peak to peak).
Audible alarm: It warns the operator in case that there are abnormalities in the current circuit, which make it difficult to obtain a reliable result.
Power supply: By means of an internal rechargeable battery, from a 12 V external battery.
Battery charger: A smart, microprocessor controlled, circuit adjusts the battery charge to the optimised parameters in order to ensure the maximum service life. It is supplied by means of an external AC adapter (provided with the equipment) or from a 12 V car battery.
Operation temperature: 14 °F to 122 °F (-10 °C to 50 °C).
Storage temperature: -13 °F to 158 °F (-25 °C to 70 °C).
Humidity: 95 % HR (without condensation).
Equipment weight: Approx. 5.07 lb (2.3 kg).
Dimension: 8.70" x 7.44" x 3.90" (221 x 189 x 99 mm).
