HZJD-3002E Earth Resistance Meter Grounding Resistance Tester

Description:
The multi-function ground resistance tester, also known as the ground resistance tester, integrates multiple measurement methods into one advanced instrument. In addition to the traditional function of measuring ground resistance by driving auxiliary ground electrodes, it also features the unique capability of measuring without auxiliary ground electrodes.Through microprocessor control, it precisely measures ground resistance using four-wire, three-wire, simplified two-wire, selective, and dual-clamp methods. The large-diameter current clamp design employs dual-clamp measurement technology, enabling online measurement without the need for auxiliary ground electrodes or isolating the grounding body from equipment. It is widely used in telecommunications, power systems, weather stations, equipment rooms, oil fields, power distribution lines, transmission towers, gas stations, factory grounding networks, lightning rods, etc. The instrument is characterized by accurate, fast, simple, stable, and reliable testing.

The multi-function ground resistance tester is microprocessor - controlled and can accurately measure ground resistance, soil resistivity, ground voltage, DC voltage, DC resistance, and AC current. It uses fast filtering technology to minimize interference. The auxiliary electrode resistance value is displayed on the same screen, making it easy to determine measurement errors caused by environmental factors and ensuring more accurate measurement of the true ground resistance value.It can store up to 500 sets of data and supports Bluetooth connectivity to a mobile app or USB connectivity to a PC for wireless or wired remote measurement, historical data retrieval, and report export. It also features unique functions such as data hold and intelligent alarm prompts.
