1. Adopt high-speed 16-bit A / D converter, with stable measurement data and good repeatability.
2. Automatic programmable current source technology, the current source has a total of 1000 current gears, which are automatically controlled by the internal microcontroller according to the measured resistance, so as to achieve a wider measurement range and the best measurement state, without the need to manually switch the current gear .
3. The response speed is fast, and the tap switch can be directly converted in the measurement state, the instrument will automatically prompt, and the new resistance value will be displayed soon.
4. Highly intelligent design, ingenious and advanced function setting, it can automatically judge the faults such as virtual connection and disconnection of the test line.
5. The protection function is perfect, which can reliably protect the impact of the back electromotive force on the instrument, and has the function of automatic discharge indication.
6. It can display measuring current and measuring time.
7. Intelligent power management technology can effectively reduce the internal heating of the instrument.
8. It can store 120 times of measurement data, and it will not be lost when power off.
