ZGY-10A DC Resistance Tester
I. Overview
With a high-speed microcontroller as the core, adopting high-speed A/D converter and programmable current source technology, it achieves excellent measurement results and highly automated measurement functions. It features high accuracy, wide measurement range, stable data, good repeatability, strong anti-interference capability, complete protection functions, and fast charge/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.
II.Main Functions and Features
1. Uses a high-speed 16-bit A/D converter, ensuring stable measurement data and good repeatability.
2. Automatic programmable current source technology, the current source has a total of 1000 current gears, automatically controlled by the internal microcontroller based on the resistance being measured, thus achieving a relatively wide measurement range 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 test leads or broken wires.
5. Complete protection functions, reliably protecting the instrument from back EMF impact, with automatic discharge indication.
6. Can display measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heat generation.
8. Can store 120 measurement data records, printable, and data is not lost upon power failure.
9. All Chinese menu and operation prompts, intuitive and convenient.
