GD3000B Digital Ground Resistance Tester
Ⅰ. Introduction
GD3000 Digital Earth Resistance Tester is specially designed and manufactured for field measurement, adopting
the latest digital and micro-processing technology, 3-pole or 2-pole method for earth resistance measurement, with a unique function of wire resistance verification, anti-interference capability
and the ability ric power, telecommunications, meteorology, oil field, construction, lightning protection, industrial electrical equipment and other earth ground resistance measurement.
GD3000 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; avto adapt to the environment, to ensure high precision, high stability and reliability for prolonged measure, which is widely used in electoid 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.
GD3000 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 400 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.
