II. 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 of output current by the internal microcontroller. The current source has 2000 current levels internally. In automatic mode, the internal microcontroller automatically controls based on the measured resistance, 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. The new resistance value will be displayed quickly without the need to restart.
4. The ZGY-40A DC Resistance Tester features highly intelligent design with clever and complete function settings, capable of automatically detecting faults such as loose test leads or broken wires.
5. The ZGY-40A DC Resistance Tester has complete protection functions, reliably protecting against back electromotive force impacts and featuring 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 data records without losing data upon power-off.
9. All menus and operation prompts are in Chinese, making it intuitive and convenient.
10. Built-in micro printer can print measurement results and memory records.
11. Non-volatile calendar and clock functions.
