1. Adopts high-speed 16-bit A/D converter, with stable measurement data and good repeatability.
2. Automatic program-controlled current source technology, with a total of 1000 current gears set in the current source, automatically controlled by the internal microcontroller according to the measured resistance, thereby achieving a relatively wide measurement range and optimal measurement state, without the need for manual current gear switching.
3. Fast response speed, allowing direct switching of the tap changer during measurement, with the instrument automatically prompting and the new resistance value quickly displayed.
4. Highly intelligent design with ingenious and advanced function settings, capable of automatically detecting faults such as loose test leads or broken circuits.
5. Comprehensive protection functions, reliably protecting the instrument from back EMF impact, with automatic discharge indication.
6. Displays measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heating of the instrument.
8. Can store 120 measurement data sets, with data retained after power-off.
9. All Chinese menu and operation prompts, intuitive and convenient.
