Product description:
To meet the needs for rapid measurement of DC resistance of inductive coils, our company has developed the DC resistance tester based on own technical advantages. With the novel power supply technology, this product features the small size, light weight, wide test range, strong anti-interference ability, complete protection functions, and large color LCD. Entirely controlled by the single-chip microcomputer, the tester is capable of automatically carrying out self-testing and data processing, and has the functions of automatic discharge and discharge indication. It also has high test accuracy and can be operated easily to rapidly measure the DC resistance.
