The functional characteristics of the DC resistance tester describe the DC resistance tester, with a high-speed microcontroller as the core, using high-speed A/D converter and program-controlled current source technology, to achieve the best measurement effect and highly automated measurement function, with high precision, measurement A wide range of functions and characteristics of the DC resistance tester Description The DC resistance tester, with a high-speed microcontroller as the core, adopts high-speed A/D converter and program-controlled current source technology, to achieve excellent measurement results and highly automated measurement functions, with high precision , Wide measurement range, stable data, good repeatability, strong anti-interference ability and perfect protection function. Features such as fast charging and discharging speed. the instrument.
Small in size, light in weight and easy to carry, it is a new generation product for transformer DC resistance testing. The DC resistance tester is small in size, light in weight and easy to carry. It has the characteristics of rapid measurement, convenient use and high measurement accuracy.
The self-test and automatic calibration functions reduce the difficulty of using and maintaining the instrument, and it is an ideal device for measuring the DC resistance of transformer windings and high-power inductive equipment. This product complies with national standards. The DC resistance tester is a new generation of transformer DC resistance tester. It can automatically select the test current according to different types of power transformers and display the test results at a fast speed. The DC resistance tester also has functions such as storage, printing, and discharge indication. It has a built-in non-power-down memory, which can save the measurement data for a long time. The use of liquid crystal display makes the instrument good man-machine interface.
The functions and features of the DC resistance tester are as follows: 1. Using a high-speed 16-bit A/D converter, the measurement data is stable and the repeatability is good. 2. Automatic program-controlled current source technology, the current source has a total of 1000 current gears, which are automatically controlled by the internal microcontroller according to the measured resistance, so as to achieve a relatively wide measurement range and optimal measurement status, without the need to manually switch current gears. 3. The response speed is fast, the tap changer can be directly switched in the measurement state, the instrument will automatically prompt, and the new resistance value will be displayed soon.
4. Highly intelligent design, ingenious and advanced function settings, can automatically judge faults such as virtual connection and disconnection of test lines. 5. The protection function is perfect, which can reliably protect the impact of the back EMF on the instrument, and has the function of automatic discharge indication. 6. The measurement current and measurement time can be displayed.
7. Intelligent power management technology can effectively reduce the internal heat of the instrument. 8. It can store 120 times of measurement data, and it will not be lost when power off. 9. All Chinese character menus and operation prompts are intuitive and convenient.
