DC Resistance Tester for Transformer DC Resistance Winding Resistance 20A

Product Description

DC resistance tester, also known as transformer DC resistance tester, DC resistance fast tester, grounding conductivity tester, using microprocessor technology, four-wire method of testing, safety, precision and reliability. Mainly used for measuring the resistance of transformer winding, transformer winding resistance, grounding lead wire conductivity test, cable wire resistance, switches, connectors, relay contact resistance, coils, motors, as well as equipment shells, lightning straps, ground beams, construction, cabinets, steel, water pipes, windows, guardrails, radiators, assembly lines, and other objects of the object of the linkage between the object of resistance testing. It is widely used in telecommunication, electric power, meteorology, machine room, oil field, electric power distribution line, tower transmission line, gas station, factory grounding network, lightning rod and so on.

DC resistance tester consists of host, monitoring software, test line, communication line and so on. Host handheld portable design for easy field application, with charging function without the need to find power on site, full-color LCD display, at a glance, touch-screen operation is convenient and easy to use, port overload prevention function. Large-capacity storage of 800 groups of data, resistance measurement range: 10.0uΩ-1000.0KΩ, measurement accuracy: ± 0.2% FS ± 10dgt. Upper computer software with historical data reading, access, save, reports and other functions.
