Features: ETCR9000S Portable Type H/L Voltage Clamp Current Leaker has broken through the traditional structure, with 32cm long insulating rod which is specially well-designed for measuring high voltage current, adopting the latest CT technology and integrated mask digital technology, portable design are fit in the measurement of H/L voltage current, leakage current which needs a safety distance. To choose different model can accurately measure 0.1mA -1000A current or leakage current. ETCR9000S Portable Type H/L Voltage Clamp Current Leaker has an innovative integrated design between transducer clamp and transducer domain, ensuring the high-precision, high-reliability, and high-stability on constant test perennially. The insulating rod is portability, have the characteristic of damp proof, high temperature resistance, shock resistance, insulating. ETCR9000S Portable Type H/L Voltage Clamp Current Leaker with an insulating rod can use to measure the wire without any insulation with voltage below 1kV or convergence generatrix. It can also use to measure the current of the wire with voltage below 10kV and the wire is with insulation layer, online current testing, and have the function of peak holding, data holding, and data storage. Its special Clamp Leaker can make it easier for clamping or evacuating the tested wire through pressing or pulling back the insulation rod, time-saving and fast, widely used in transformer substation, power plant, industrial and mining enterprises as well as the inspection station and electrician maintenance departments for electrical current detection and field electrical operations. It can also replace the H/L voltage transforming ratio tester, that is, to detect the high and low current for primary circuit and secondary circuit separately, and then calculate to conclude the change of high and low pressure Technical Specification: Function High/Low voltage AC current measurement, leakage current measurement, on-line AC current test, load current measurement Power Supply DC6V Alkaline Dry Battery (1.5V AAA X 4) Size of jaw 48mm range 0.
