1. Uses high-speed 16-bit A/D converter, providing stable measurement data and good repeatability.
2. Automatic program-controlled current source technology, with a total of 1000 current levels set by the internal microcontroller based on the measured resistance, achieving a wide measurement range and optimal measurement state without manual current switching.
3. Fast response speed; the tap changer can be switched directly during measurement, and the instrument will automatically prompt, with new resistance values displayed quickly.
4. Highly intelligent design with advanced and clever function settings, capable of automatically detecting faults such as loose test leads or broken circuits.
5. Comprehensive protection functions, reliably protecting the instrument from back EMF impact, with automatic discharge indication.
6. Displays measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heat generation.
8. Can store 120 measurement data sets, which are not lost upon power failure.
9. All Chinese menu and operation prompts, intuitive and convenient.
Product Features
1. Adopts brand-new power supply technology, with rapid measurement, compact size, and easy use.
