WX3000 Digital Earth Resistance Tester
Belongs to category： Earth Resistance Tester
Product Introduction
WX3000 Digital Earth Resistance Testeris 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 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.
WX3000 Digital Earth Resistance Testerhas 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.
WX3000 Digital Earth Resistance Testeris composed of host machine, monitoring software, testing wires, communication wires and others. The large LCD display ofhost 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 throughmonitoring 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.
