Description - TENTECH MTD 20KWe Manual De Uso

1. Description

The MTD20KWe digital earth tester allows for the measurement of Earth
Resistances and Soil Specific 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 engineering. 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.
It has an audible signal which advises the operator when the generated
current is not enough to carry out reliable measurements. Due to the fact
that it may not be noticed, this alarm also prevents further testing.
Because of its wide range of measurement (from 0.01 Ω up to 20 kΩ), this
equipment allows for reliable testing in all kinds of soils, including those
that offer very high resistivity. The use of this instrument is very simple, it
has a high-visibility 3½ - digit display with direct readings, even under
sunlight.
This earth tester is supplied with a rechargeable internal battery. The
smart charger is microprocessor-controlled, and can be powered from a
12 V car battery (or a similar one).
It has a sturdy, easy and safe to carry cabinet, with IP54 protection level.
It is suitable to work under adverse geographical and environmental
conditions, with extreme temperatures in cold or tropical regions and in
high mountain areas, showing a reliable performance in the field.
