The XHDJ705 digital ground resistance tester is a microprocessor-based earth resistance meter designed for on-site acceptance and periodical inspection of earthing systems. It performs precision 3-wire and simple 2-wire earth resistance measurements across three gears from 0.01Ω to 2000Ω, and also measures AC earth voltage up to 600V, so field engineers can verify both the resistance of the earth electrode and the presence of dangerous stray voltage with one portable instrument.

Every unit delivered with its individual factory test report and 12-month warranty
Every XHDJ705 is calibrated at our Xi'an factory before delivery against a JDB-2 ground resistance meter calibration device (accuracy class 0.05, certificate No. DYQ20241014). The sample report below (instrument Serial No. 30130572, test date 2024-04-07) covers the 20Ω, 200Ω and 2000Ω resistance gears and the AC voltage function. Permissible error in all gears: ±(2%rdg+3dgt). All measured items passed, and the whole-machine conclusion is Qualified. A printed test report accompanies each delivered unit for your acceptance file.
