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 switching of current gears.
3. Fast response speed, can directly switch the tap changer in the measurement state, the instrument will automatically prompt, and the new resistance value will be displayed soon.
4. Highly intelligent design, with ingenious and advanced function settings, can automatically judge faults such as loose connection or disconnection of test leads.
5. Complete protection functions, can reliably protect 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 can effectively reduce internal heating of the instrument.
8. Can store 120 measurement data, which will not be lost after power failure.
9. All Chinese menus and operation prompts, intuitive and convenient.
