HZJD-3002E Multi-function Ground Resistance Tester
The multi-function ground resistance tester is microprocessor - controlled andcan 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 easyto determine measurement errors caused by environmental factors and ensuring moreaccurate measurement of the true ground resistance value.It can store up to 500 sets ofdata and supports Bluetooth connectivity to a mobile app or USB connectivity to a PCforwireless or wired remote measurement, historical data retrieval, and report export. It alsofeatures unique functions such as data hold and intelligent alarm prompts.
