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, with stable testing, high measurement accuracy, and fast speed, improving measurement efficiency and reducing the work intensity of operators. Technically, it uses "four-terminal" measurement to eliminate measurement errors caused by lead resistance and contact. It has overvoltage protection function 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.
Product features of transformer DC resistance tester: 1. Uses a 32-bit ARM core as the processing core, with stable measurement data and good repeatability.
2. Automatic program-controlled current source technology, automatically controlled by the internal microcontroller according to the measured resistance, thereby achieving a wider measurement range and better measurement state, without the need for manual switching of current gears.
3. Fast response speed. In the measurement state, the tap changer can be directly switched, and the instrument will automatically prompt. The new resistance value will be displayed quickly.
4. Highly intelligent design with clever and advanced function settings, capable of automatically detecting faults such as loose test leads and open circuits.
5. Complete protection functions, reliably protecting the instrument from back electromotive force impact, with automatic discharge indication function.
6. Can display measurement current and measurement time.
7. Intelligent power management technology effectively reduces internal heating of the instrument.
8. Has large-capacity storage function, built-in lithium battery, can store 2000 test records.
9. Uses 65K true color LCD display, Chinese menu prompts, convenient operation.
10. The digital resistance tester has high measurement accuracy, stable performance, clear display, wide measurement range, and strong anti-interference ability.
Transformer DC resistance tester unique advantages:
1. Fast testing speed: The maximum output charging current can reach 3A. During measurement, it can effectively compensate for the current inertia of large inductance equipment, accelerate core saturation, thereby shortening charging time and improving testing speed. It is hundreds of times faster than traditional single-arm and double-arm bridges.
2. High accuracy: In addition to using 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 capability and strong anti-interference ability, thereby ensuring measurement accuracy. It also uses imported high-quality components from abroad, ensuring high measurement accuracy and good repeatability.
3. Wide measurement range: The resistance measurement range is 1μΩ～2KΩ, with a wide range.
4. Dual AC/DC power supply: This DC resistance fast tester has a built-in rechargeable battery pack, supports AC/DC power supply, portable design, convenient to use and carry.
