Brief introduction:
ETCR9000 Series H/L Voltage Clamp Meter has broken through the traditional structure, which is specially well-designed for measuring high voltage current, adopting the latest CT technology and integrated mask digital technology, formed by composition of a special use clamp meter with a high-voltage insulation rod, as to ETCR9000A type -- infrared transmission of test data, also equipped with receivers, which can monitor the tested data in a long distance on real-time. If not using an insulation rod, it can be also used as a high precision low-voltage clamp meter, or an alternating current meter, which can accurately measure 1mA of current or leakage current.
ETCR9000 Series H/L Voltage Clamp Meter has an innovative integrated design between transducer clamp and transducer domain, ensuring the high-precision, high-reliability, and high-stability on constant test perennially.
ETCR9000 Series H/L Voltage Clamp Meter is connected with insulation rod, which can be used for measuring high voltage current that is below 23KV, on-line current measurement, also having peak maintenance, data preservation, data storage, infrared transmission and other functions, and its special clamp meter 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. The insulation rod is light and convenient, with the advantages of anti-moisture, high temperature resistance, anti-impact, bending resistance, high insulation, flexibility and other characteristics.
