Brand New AST-40A Three-Channel DC Resistance Tester
Features
1. Uses a high-speed 16-bit A/D converter, providing stable measurement data and good repeatability.
2. Automatic programmable 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 without manual current switching.
3. Fast response speed; the tap changer can be switched directly during measurement, and the instrument will automatically prompt, with the new resistance value displayed quickly.
4. Highly intelligent design with clever and advanced function settings, capable of automatically detecting faults such as loose or broken test leads.
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, retained even when power is off.
9. All Chinese menus and operation prompts, intuitive and convenient.
Routine Maintenance
1. Within three months, if the instrument fails to meet technical requirements due to its own reasons, it can be replaced unconditionally.
2. Free repair within one year, and lifetime maintenance and technical service.
3. If the instrument has quality issues, a maintenance plan will be proposed on the same day, and on-site handling will be timely. Alternative instruments can also be provided to meet user needs.
4. Free on-site training on instrument usage knowledge.
5. If the instrument malfunctions, please contact us promptly so that we can provide service.
