1. Uses high-speed 16-bit A/D converter, measurement data is stable and repeatable.
2. Automatic program-controlled 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 current gear switching.
3. Fast response speed, can directly switch tap changer in measurement state, the instrument will automatically prompt, and the new resistance value will be displayed soon.
4. Highly intelligent design, with clever and advanced function settings, can automatically judge faults such as loose test line connection and disconnection.
5. Complete protection functions, can reliably protect the instrument from back EMF impact, with automatic discharge indication function.
6. Can display measurement current and measurement time.
7. Intelligent power management technology can effectively reduce internal heating of the instrument.
8. Can store 120 measurement data, not lost after power off.
9. All Chinese menu and operation prompts, intuitive and convenient.
