Introducing the reverse characteristic test of Automotive Wiring Harness Protection Sleeve

With the continuous development of the economy and society, the things we use are also constantly changing. For example, Automotive Wiring Harness Protection Sleeve are an effective case. With the development trend of Automotive Wiring Harness Protection Sleeve, we focus on automobile wiring harness protection. The covers are becoming more and more understood. What the Automotive Wiring Harness Protection Sleeve manufacturers want to tell you is the reverse test of the Automotive Wiring Harness Protection Sleeve.

To test the characteristics in the reverse direction, touch the red test lead of the multimeter to the positive level of the Automotive Wiring Harness Protection Sleeve, and touch the black test lead to the negative level of the Automotive Wiring Harness Protection Sleeve. If the meter rod finger is at or close to the maximum value, the pipe will be damaged. is in compliance with the standards.
For the positive direction characteristic test, touch the black test lead of the multimeter to the positive level of the Automotive Wiring Harness Protection Sleeve, and touch the red test lead to the negative level of the Automotive Wiring Harness Protection Sleeve. If the pointer is not placed at 0 but just stops in the middle of the dial, the resistance at this time is the positive resistance of the car wiring harness protective cover. Generally, the lower the positive resistance, the better. If the forward resistance is 0, it means the core tube is short-circuited and damaged. If the forward resistance is close to a high value, it means the core tube is short-circuited. Short-circuited and open-circuited pipes cannot be used.
Electronic switches and Automotive Wiring Harness Protection Sleeve have little resistance under the action of working voltage in the forward direction and are in an on-off state, which is equivalent to an connected power switch; under the action of reverse direction current, the resistance is very large and are in a cut-off state, like a broken switch, using the switching characteristics of the Automotive Wiring Harness Protection Sleeve, various sequential logic circuits can be formed. Detection car wiring harness protective cover, which plays the detection function in the tape recorder. Variable capacity car wiring harness protective cover, used in TV tuners.
Limiting component, after the forward direction of the Automotive Wiring Harness Protection Sleeve is passed through, the forward pressure drop will basically remain unchanged. The silicon tube is 0.7V and the germanium tube is 0.3V. This feature is used as a limiting component in the power circuit. It can limit the strength of the signal within a certain area, relay the current in the wiring harness protective cover, the inductor of the power supply circuit and the relay, etc.
