Introduction:

Portable DC Resistance Tester, also known as transformer DC resistance tester, DC resistance rapid tester, grounding conductivity tester, adopts microprocessor technology, four-wire test, safe, precise and reliable.

Is mainly used for measurement of transformer winding resistance, transformer winding resistance, ground down lead conduction testing, the wire resistance of the cable, switch, socket, relay contact resistance, winding, motor, shell and equipment, lightning protection zone, ground beam, structure, rack, steel, pipe, Windows, fence, radiator, pipeline connection between objects such as metal components resistance test.

It is widely used in telecommunication, electric power, meteorology, machine room, oil field, electric power distribution line, tower transmission line, gas station, factory grounding grid, lightning rod and so on.

Portable DC Resistance Tester is composed of a host, monitoring software, test line and communication line.

Host handheld portable design is convenient for field application, with charging function without on-site power search, full-color large LCD display, clear at a glance, easy to use touch screen operation, port overload protection function.

Large capacity storage 500 groups of data, resistance measurement range: 10.0 u Ω 50.00 K Ω, measuring accuracy: ±0.2%FS±10dgt.

The upper computer software has the functions of reading, consulting, saving and reporting historical data.
