HSZR-20A DC Resistance Tester

1HSZR-20A DC Resistance TesterMAIN FUNCTION AND FEATURES

1. Using a high-speed 16 bit A/D converter, the measurement data is stable and has good repeatability.

2. Automatic programmable current source technology, with a total of 1000 current gears set for the current source, automatically controlled by an internal microcontroller based on the measured resistance, achieving a wide measurement range and optimal measurement state without the need for manual switching of current gears.

3. Fast response speed, can directly switch to tap changer in measurement state, the instrument will automatically prompt, and the new resistance value will be displayed quickly.

4. Highly intelligent design, cleverly advanced functional settings, and automatic detection of faults such as virtual connection and disconnection of test lines.

5. The protection function is complete and can reliably protect against the impact of back electromotive force on the instrument, with automatic discharge indication function.

6. It can display the measured current and measurement time.

7. Intelligent power management technology can effectively reduce internal heating of instruments.

8. Can store 150 measurement data, no loss in case of power failure.

9. All Chinese character menus and operation prompts are intuitive and convenient.
