The transformer DC resistance tester uses a 32-bit ARM core as the processing core to control the entire 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 current source linear compensation technology, providing stable testing, high measurement accuracy, and fast speed, which improves measurement efficiency and reduces 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 to prevent back electromotive force impact. A 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, providing stable measurement data and good repeatability.
2. Automatic program-controlled current source technology, controlled automatically 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 switched directly 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 test leads or broken wires.
5. Comprehensive protection functions, reliably protecting against back electromotive force impact on the instrument, with automatic discharge indication.
6. Can display measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heating of the instrument.
8. Large storage capacity, 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 testing speed: The maximum output charging current can reach 3A, effectively compensating for the current inertia of large inductive equipment during measurement, accelerating core saturation and thus shortening charging time, improving testing speed, and being hundreds of times faster than traditional single/double arm bridges.
2. High accuracy: In addition to using 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 also 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. AC/DC dual use: This DC resistance fast tester has a built-in rechargeable battery pack, supports AC/DC power supply, and features a portable design for convenient use and carrying.
