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, providing stable measurement data and good repeatability.
2. The ZGY-40A DC Resistance Tester features automatic program-controlled 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 adjusts the output current based on the resistance being measured, achieving a 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 clever 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 against back EMF 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 heating of the instrument.
8. It can store up to 250 measurement records, which are retained even when power is off.
9. All menus and operation prompts are in Chinese, providing intuitive and convenient operation.
10. Built-in micro printer for printing measurement results and memory records.
11. Non-volatile calendar and clock functions.
