The transformer DC resistance tester uses a 32-bit ARM core as the processing core to control the whole machine, automatically completing functions such as self-calibration, stable current judgment, data processing, and resistance value display. It can measure the DC resistance of various types of transformers and mutual inductors.
The transformer DC resistance tester adopts a current source linear compensation technology, which ensures stable testing, high measurement accuracy, and fast speed, improving measurement efficiency and reducing the operator's workload. Technically, it uses the "four-terminal" measurement method to eliminate measurement errors caused by lead resistance and contact resistance. It has overvoltage protection and can resist back electromotive force impact. The panel printer can quickly print measurement results (optional). It is small in size, light in weight, and easy to carry.
Transformer DC resistance tester product features:
1. Uses a 32-bit ARM core as the processing core, ensuring stable measurement data and good repeatability.
�� 2. Automatic program-controlled current source technology, automatically controlled by the internal microcontroller based on the measured resistance, achieving a wide measurement range and optimal measurement state without manual current range switching.
3. Fast response speed; the tap changer can be directly switched during measurement, and the instrument will automatically prompt, with the new resistance value displayed quickly.
4. Highly intelligent design with advanced and ingenious function settings, capable of automatically detecting faults such as loose or broken test leads.
5. Comprehensive protection functions, reliably protecting the instrument from back electromotive force impact, with automatic discharge indication.
6. Can display measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heat generation.
8. Large-capacity storage function, built-in lithium battery, can store 2000 test records.
9. Uses 65K true color LCD display with Chinese menu prompts for convenient operation.
10. The digital resistance tester has high measurement accuracy, stable performance, clear display, wide measurement range, and strong anti-interference capability.
Transformer DC resistance tester unique advantages:
1. Fast test speed: The maximum output charging current can reach 3A. During measurement, it can effectively compensate for the current inertia of large inductive equipment, accelerate core saturation, shorten charging time, and improve test speed, which is hundreds of times faster than traditional single/double-arm bridges.
2. High accuracy: In addition to the advanced four-terminal measurement method, this instrument also adopts advanced constant current power supply technology, keeping the charging current for inductive loads at a relatively stable value, with stable inductance resistance and strong anti-interference capability, thereby ensuring measurement accuracy. It uses high-quality imported components, ensuring high measurement accuracy and good repeatability.
3. Wide measurement range: The resistance measurement range is 1μΩ to 2KΩ, with a wide range.
4. Dual AC/DC power supply: This DC resistance fast tester has a built-in rechargeable battery pack, supports both AC and DC power supply, and features a portable design for convenient use and carrying.
