Product Details

I. Overview

With a high-speed microcontroller as the core, and adopting high-speed A/D converter and programmable current source technology, it achieves measurement effectiveness and highly automated measurement functions. It features high precision, wide measurement range, stable data, good repeatability, strong anti-interference capability, and complete 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.

II. Main Functions and Features

1. Adopts high-speed 16-bit A/D converter, providing 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 according to the measured resistance, thus achieving a relatively wide measurement range and optimal measurement state without manual switching of current gears.

3. Fast response speed: the tap changer can be directly switched during measurement, and the instrument will automatically prompt; the new resistance value will be displayed quickly.

4. Highly intelligent design with ingenious and advanced function settings, capable of automatically detecting faults such as loose or broken test leads.

5. Complete protection functions: reliably protects the instrument from back EMF impact and has an automatic discharge indication function.

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 without loss upon power failure.

9. All Chinese menus and operation prompts are intuitive and convenient.

10. Equipped with a printer to print test results.
