The resistance tester can be applied to the winding resistance of transformers, inductors, motors, deflection coils, high-precision high, medium and low value resistors. Wire resistance; metal riveting resistance for cars, ships, and airplanes. It has high accuracy. In addition to the advanced four-terminal measurement method, it also uses advanced constant current power supply technology to keep the charging current of the inductive load at a relatively stable value, stable anti-inductive ability, and strong anti-interference ability. . The maximum output charging current can reach 2A, which can effectively compensate the current inertia of the large-inductance device during measurement, accelerate the core saturation, thereby shortening the charging time and improving the test speed, which is hundreds of times faster than the traditional single- and double-arm bridges .
The resistance tester has an overcurrent protection function. When the loop current exceeds 30A, the instrument emits an overcurrent sound and light alarm. This is also to improve the safety of the equipment. Only the correct operation process can guarantee the service life of the equipment. During the operation of the resistance tester, the connection between the test clip and the contact part should be tight and reliable to avoid unstable readings.
The tools and all accessories necessary for the measurement of the resistance tester, and wipe the instrument and the ground probe, especially the resistance of the ground probe. The application market of the resistance tester must affect the surface of the dirt and rust stains Clean up. When the resistance tester is in operation, keep the surface to be tested clean and free from contamination.
