Product Introduction
The transformer DC resistance tester is centered on a high-speed microcontroller, adopting high-speed A/D converter and programmable current source technology, achieving excellent measurement results and highly automated measurement functions. It features high accuracy, wide measurement range, stable data, good repeatability, strong anti-interference capability, and comprehensive protection functions. It also has fast charge and discharge speed. This instrument is small in size, light in weight, and easy to carry, making it a new generation product for transformer DC resistance testing.
Main functions and features of the transformer DC resistance tester:
1. Adopts 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, automatically controlled by the internal microcontroller based on the measured resistance, thereby achieving a relatively wide measurement range and optimal measurement state without manual current gear switching.
3. Fast response speed; in measurement state, the tap changer can be directly switched, and the instrument will automatically prompt, with the new resistance value displayed quickly.
4. Highly intelligent design with clever and advanced function settings, capable of automatically detecting faults such as loose or broken test leads.
5. Comprehensive protection functions, reliably protecting the instrument from back electromotive force impact, with automatic discharge indication.
6. Displays measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heat generation.
8. Can store 120 measurement data records without loss upon power failure.
9. All Chinese menu and operation prompts, intuitive and convenient.
