Transformer DC Resistance Tester Product Features:
1. Fast test speed: the larger output charging current can reach 3A, which can effectively compensate for the current inertia of large inductance equipment during measurement, accelerate the saturation of the iron core, shorten the charging time, improve the test speed, and be hundreds of times faster than the single and double arm bridges of traditional instruments.
2. High accuracy: In addition to the advanced four-terminal measurement method, this instrument also adopts advanced constant current power supply technology, so that the charging current of the inductive load is kept at a relatively stable value, the anti-induction ability is stable, and the anti-interference ability is strong, so as to ensure the measurement accuracy. And the use of imported high-quality components, the measurement results are highly accurate and repeatable.
3. Wide measurement range: the resistance measurement range is 1 2K, and the measuring range is wide.
4. AC and DC dual-purpose: This DC resistance fast tester is equipped with a rechargeable battery pack, AC and DC power supply, portable design, easy to use and carry.
