Shanghai Shenggao Electric Technology Co., Ltd. produces and sellsSG6416Loop resistance testerUsed for measuring the loop resistance and leakage current of lightning protection devices, to determine whether the connection of lightning protection devices is reliable and to troubleshoot faults. When measuring the resistance of a loop, there is no need to disconnect the wiring of the loop. Simply clamp the circuit with a clamp meter to measure the resistance of the loop. This clamp meter can also simultaneously test the leakage current in the loop. This clamp table is widely used in construction quality inspection stations, supervision companies, construction units, lightning protection companies, power departments, etc., within the scope specified in the National Meteorological Administration Order No. 31 [Management Measures for Lightning Protection Device Testing Qualifications].
