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 values or automatic control 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. The tap changer can be switched directly 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 comprehensive function settings, capable of automatically detecting faults such as loose or broken test leads.
5. The ZGY-40A DC Resistance Tester has comprehensive protection functions, reliably protecting the instrument from back-EMF impact, 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 heating 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.
