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 features automatic programmable current source technology, allowing manual selection of typical output current or automatic control of output current by the internal microcontroller. The current source has a total of 2000 current levels internally. In automatic mode, the internal microcontroller automatically controls based on the resistance being measured, thereby achieving a relatively wide measurement range and the *optimal measurement state.
3. The ZGY-40A DC Resistance Tester provides real-time dynamic display with fast response speed. The tap changer can be directly switched 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 *perfect 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 the impact of back electromotive force on the instrument, and features automatic discharge indication.
6. ZGY-40A DC Resistance Tester can display measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heat generation of the instrument.
8. Can store 250 measurement data records, which are not lost upon power failure.
9. All Chinese menu and operation prompts are intuitive and convenient.
10. Built-in micro printer can print measurement results and memory records.
11. Non-volatile calendar and clock functions.
