ZGY-40A DC Resistance Tester Main Functions and Features
1. The ZGY-40A DC Resistance Tester uses a high-speed 16-bit A/D converter, ensuring stable measurement data and good repeatability.
2. The ZGY-40A DC Resistance Tester adopts automatic programmable current source technology, allowing manual selection of typical output current values or automatic control by the internal microcontroller. The current source has a total of 2000 current levels. In automatic mode, the internal microcontroller controls the output current based on the resistance being measured, thereby achieving a relatively wide measurement range and optimal measurement state.
3. The ZGY-40A DC Resistance Tester provides real-time dynamic display with fast response. It can directly switch tap changers during measurement, and the instrument will automatically prompt, with the new resistance value displayed quickly without needing to restart.
4. The ZGY-40A DC Resistance Tester features highly intelligent design with ingenious function settings, capable of automatically detecting faults such as loose test leads or broken wires.
5. The ZGY-40A DC Resistance Tester has comprehensive protection functions, reliably protecting the instrument from back-EMF impacts, and includes an automatic discharge indication.
6. The ZGY-40A DC Resistance Tester can display measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heat generation.
8. It can store 250 measurement records, which are retained even when power is off.
9. All menus and operation prompts are in Chinese, making it intuitive and convenient.
10. Built-in micro printer for printing measurement results and stored records.
11. Non-volatile calendar and clock functions.
