Overview:

The DC resistance tester is a new generation of transformer DC resistance testing instruments. It can automatically select the test current according to different types of power transformers and display the test results at the fastest speed. The DC resistance tester also has functions such as storage, printing, and discharge indication. It is equipped with a non-volatile memory that can store measurement data for a long time. The adoption of a liquid crystal display gives the instrument a good human-machine interface, making it the preferred equipment in DC resistance testing work. The DC resistance tester is a high-precision, wide-range resistance tester controlled by a high-performance microprocessor. It can test resistances from 1μΩ to 3MΩ with a maximum display of 30,000 counts. The highest test speed is 60 times/second. At a test speed of 15 times/second, it can still guarantee an accuracy of 0.05%, and the reading fluctuation can be controlled within 3 digits. It comes standard with temperature compensation function, allowing precise testing of meter resistors. Three current modes can meet various demanding resistance testing requirements.

The transformer DC resistance tester (micro-ohmmeter) is a high-precision replacement product for DC single and double-arm bridges. The SX-2A transformer DC resistance tester adopts advanced switching power supply technology, with a four-and-a-half-digit LCD displaying measurement results and a three-and-a-half-digit LCD displaying ambient temperature or test current value, overcoming the disadvantage of other similar products with LED displays that are difficult to read in sunlight. At the same time, it has an automatic arc suppression function

Functional Features

1. Uses a high-speed 16-bit A/D converter, ensuring stable measurement data and good repeatability.

2. Automatic programmable current source technology, with a total of 1000 current gears set in the current source, automatically controlled by the internal microcontroller according to the measured resistance, thereby achieving a relatively wide measurement range and optimal measurement state, without the need for manual current gear switching.

3. Highly intelligent design, capable of automatically detecting faults such as loose or broken test leads.

4. Complete protection functions, reliably protecting the instrument from back electromotive force impact, with automatic discharge indication function.

5. Can display measurement current and measurement time. Intelligent power management technology effectively reduces internal heating of the instrument.

6. Can store 120 measurement data, which will not be lost upon power failure. All Chinese menu and operation prompts are intuitive and convenient.
