Introduction The measurement of DC resistance is a must-test item for semi-finished products and finished products in the manufacture of inductive coils such as transformers, mutual inductors, reactors, and electromagnetic operating mechanisms. Welding, loose connection parts, missing strands, broken wires and other manufacturing defects and hidden dangers after operation. In order to meet the needs of rapid measurement of the DC resistance of the inductive coil, our company has developed a DC resistance tester using its own technical advantages. The instrument adopts a new power supply technology and has the characteristics of small size, light weight, wide test range, strong anti-interference ability, perfect protection function, and large-screen color liquid crystal display. The whole machine is controlled by a single-chip microcomputer, which automatically completes self-checking and data processing, and has the functions of automatic discharge and discharge indication. The instrument has high test accuracy, simple operation, and can realize fast measurement of direct resistance. Features 1. The instrument provides 6 output current options, the maximum current: 20A, the minimum current: <5mA, suitable for measuring the DC resistance of more types of transformers and transformers. 2. The measuring range of the instrument is wide from 100μΩ to 100kΩ. 3. The response speed is faster, the on-load tap-changer can be directly converted in the measurement state, and the instrument automatically refreshes the data. 4. The instrument has an audio discharge alarm function, and the discharge indication is clear to reduce misoperation. 5. The protection function is perfect, which can reliably protect the impact of the back EMF on the instrument, and the performance is more reliable. 6. The instrument adopts a 7-inch color LCD screen, and the interface display is clear and beautiful. And real-time print output results. 7. Built-in Chinese and English versions of the operation interface can be freely switched according to customer needs. 8. With RS485 communication interface, the test data can be transmitted to the background. 9. The machine has a large storage capacity and can store up to 500 test records. 10. With a USB interface, the test data can be transferred to the U disk. 11. The parameter setting is more perfect, you can set the test winding of the transformer, the tap position, the test phase, the temperature of the test product, the converted temperature value, etc. 12. The instrument adopts an industrial plastic case, which is easy to carry and improves the service life. Parameters
