The digital grounding resistance tester is specially designed and manufactured for on-site measurement of grounding resistance. It adopts the latest digital and micro-processing technology, and the 3-wire or 2-wire method measures the grounding resistance. It has a unique line resistance verification function, anti-interference ability and environment. Adaptability to ensure high accuracy, high stability and reliability for long-term measurement. It is widely used in grounding resistance measurement of power, telecommunications, meteorology, oil fields, construction, lightning protection and industrial electrical equipment.
The digital grounding resistance tester has a unique line resistance verification function, which is more accurate for the measurement of low-level grounding resistance on site, which can avoid errors caused by long-term use of the line resistance of the test line; it can avoid the test line not being fully inserted into the instrument interface Or errors caused by poor contact; can avoid errors caused by user replacement or lengthening of the test line.
The instrument is composed of host computer, monitoring software, test line, communication line and so on. Realize historical query and online real-time monitoring function through monitoring software, dynamic display, with maximum, minimum and average indication, with alarm value setting and alarm indication function, with historical data reading, consulting, saving, reporting, printing and other functions.
