Description
ETCR***0 Digital Earth Resistance Tester
Ⅰ. Introduction
ETCR***0 Digital Earth Resistance Tester is specially designed and
manufactured for field measurement, adopting the latest digital and
micro-processing technology, *-pole or *-pole method for earth
resistance measurement, with a unique function of wire resistance
verification, anti-interference capability and the ability to adapt
to the environment, to ensure high precision, high stability and
reliability for prolonged measure, which is widely used in electric
power, telecommunications, meteorology, oil field, construction,
lightning protection, industrial electrical equipment and other
earth ground resistance measurement.
ETCR***0 Digital Earth Resistance Tester has a unique function of
wire resistance verification，more accurate on measuring on-site low
value earth ground resistance, which can avoid error caused by
resistance change due to prolonged usage of testing wire; avoid
error caused by testing wire that is failed to be fully inserted
into tester interface or by poor contact; avoid error caused by
users replacing or lengthening testing wires.
ETCR***0 Digital Earth Resistance Tester is composed of host
machine, monitoring software, testing wires, communication wires
and others. The large LCD display of host machine is with blue
backlight and bar graph indicating that can be seen clearly. At the
same time it can store **0 sets of data, fulfilling historical
inquiry and online real-time monitoring through monitoring
software, dynamic display, with the maximum, minimum, and mean
indicators, with alarm settings and alarm indicator, and with the
functions like historical data access, reading, preservation,
report forms, printing and so on.
