Introduction:

This DC resistance tester is also known as transformer DC resistance tester, DC resistance rapid tester, grounding conduction tester, using microprocessor technology, four-wire method test, safe, precise and reliable.

It is mainly used to measure the resistance of transformer winding, transformer resistance resistance, grounding conductor conduction test, wire resistance, cable switch, connector, relay, contact resistance, coil, motor, equipment shell, lightning belt, beam, structure, cabinet, steel bar, water pipe, window, guardrail, radiator, line test between metal components.

Widely used in telecommunications, electric power, meteorology, machine room, oil field, power distribution line, iron tower transmission line, gas station, factory grounding network, lightning rod, etc.

The DC resistance tester is composed of the host machine, monitoring software, test line, communication line, etc.

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

Large capacity storage of 800 sets of data, resistance measurement range: 10.0uΩ-1.0000 MΩ, measurement accuracy: ± 0.2%FS ± 10 dgt.

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