10A DC Resistance Tester
Product Overview:
The 10A DC resistance tester is powered by both AC and DC power supplies, with a wide measurement range and high test accuracy, which is beneficial for field testing. The whole machine is controlled by a high-speed microcontroller, featuring high automation, fast response, and automatic completion of test data processing and automatic discharge functions. This DC resistance tester has comprehensive protection functions, reliably protecting the instrument from back EMF impacts, with more reliable performance, enabling rapid measurement of DC resistance.
Technical Parameters:
1. Output current: 10A, 5A, 1A, 200mA, 40mA, 5mA
2. Measurement range: 1mΩ to 20KΩ
3. Measurement accuracy: 0.2%
4. Resolution: 0.1μΩ
5. Power supply: AC/DC power supply
6. Ambient temperature: 0 to 40°C
7. Ambient humidity: ≤90%RH, no condensation
Main Features:
1. Adopts a high-speed 16-bit A/D converter, ensuring stable measurement data and good repeatability.
2. The 10A DC resistance tester uses automatic program-controlled current source technology. The current source has a total of 1000 current gears, automatically controlled by the internal microcontroller according to the measured resistance, thus achieving a relatively wide measurement range without manual current gear switching.
3. Fast response speed. The tap changer can be directly switched 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 impacts, with automatic discharge indication.
6. Can display measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heat generation.
8. Can store 120 measurement data records, which are not lost upon power failure.
9. All Chinese menus and operation prompts, intuitive and convenient. 10. The digital resistance meter features high measurement accuracy, stable performance, clear display, wide measurement range, and strong anti-interference capability.
Precautions:
1. After each test, wait for the discharge indication to end before removing the test leads. Operators should pay attention to safety.
2. If any abnormal situation occurs during measurement, press the reset button or power off. If normal operation cannot be restored, please contact our company and do not disassemble the instrument yourself.
