Performance Features
1. Adopts high-speed 16-bit A/D converter, providing stable measurement data and good repeatability.
2. Automatic program-controlled current source technology, allowing manual selection of typical output current values or automatic control by the internal microcontroller. The current source has 4000 current levels internally, and in automatic mode, the internal microcontroller adjusts the output current based on the resistance being measured, achieving a wide measurement range and optimal measurement conditions.
3. Real-time dynamic display with fast response. The tap changer can be switched directly during measurement, and the instrument will automatically prompt, with the new resistance value displayed quickly without needing to restart.
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 back EMF impacts, with automatic discharge indication.
6. Displays measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heat generation.
8. Can store up to 250 measurement records, with data retained even when power is off.
9. Full Chinese menu and operation prompts, intuitive and convenient.
10. Built-in micro printer for printing measurement results and stored records.
11. RS-232 interface for communication with a computer.
12. Non-volatile calendar and clock functions.
