XHHL Series loop resistance tester is a high-precision, digital switch detection instrument developed by the company based on the IEC standard and the relevant provisions of the People's Republic of China's latest power implementation standard DL/T845.4-2004. The instrument uses high-frequency high-power constant-current switching power supply technology, which can measure the micro-ohm contact resistance. Widely used in the measurement of contact resistance, loop resistance, cable and wire and weld contact resistance of various switches and electrical appliances. The instrument has accurate measurement data and stable performance. It can meet the high-voltage switch repair and high-voltage switch factory loop resistance test of power supply and power supply departments. Claim. The output current and measurement resistance are output at the same time on the 65K true color liquid crystal. The measurement result can be stored in the U disk for voltage output. The power-off memory can satisfy the data query at any time.
