The XHDQ703 Single-jaw Earth Resistance Tester is widely applied to measure earth resistance and loop resistance for electrical equipment in power, meteorology, oilfield, construction and industrial sectors. When measuring earthed systems with loops, it requires no disconnection of earth down-leads or auxiliary electrodes. This tester is capable of detecting earth faults that cannot be measured by traditional methods and is suitable for scenarios where conventional measurement approaches are inapplicable. The XHDQ series clamp-on earth resistance testers measure the combined value of earth electrode resistance and earth lead resistance.
