HSZR-40A DC Resistance Tester

1HSZR-40A DC Resistance TesterMain functions and features:

• Using a high-speed 16 bit A/D converter, the measurement data is stable and has good repeatability.
• Automatic programmable current source technology allows for manual selection of typical output current values or automatic control of output current by an internal microcontroller. The current source has a total of 2000 current levels, and in automatic mode, the internal microcontroller automatically controls the measured resistance to achieve a wide measurement range and optimal measurement state.
• Real time dynamic display, 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 quickly without restarting.
• Highly intelligent design, cleverly advanced functional settings, and automatic detection of faults such as virtual connection and disconnection of test lines.
• The protection function is complete and can reliably protect against the impact of back electromotive force on the instrument, with automatic discharge indication function.
• It can display the measured current and measurement time.
• Intelligent power management technology can effectively reduce internal heating of instruments.
• Can store 250 measurement data without loss in case of power failure.
• All Chinese character menus and operation prompts are intuitive and convenient.
• Built in micro printer, capable of printing measurement results and memory records.
• Non power off calendar, clock function.
