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, thus achieving a relatively wide measurement range and optimal measurement state, without the need for manual switching of current gears.
3. Fast response speed, allowing direct switching of tap changers in the measurement state. The instrument will automatically prompt, and 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 test leads or open circuits.
5. Comprehensive protection functions, reliably protecting the instrument from the impact of back electromotive force, with automatic discharge indication function.
6. Can display measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heat generation of the instrument.
8. Can store 120 measurement data records, which are not lost upon power failure.
9. All Chinese menus and operation prompts, intuitive and convenient.
