Reverse Characteristic Test of PET Self-wrapping Braided Sleeve

With the continuous development of social economy, the items used by people are also constantly changing. For example, PET Self wrap braided sleeve is a good example. With the development of PET Self Wrap Braided Sleeve, people There is more and more understanding of Pet Self Wrap Braided Sleeve. What I want to tell you about the Open Type Braided Sleeve is the reverse test of PET Self Wrap Braided Sleeve.

Reverse characteristic test, touch the red test pen of the multimeter to the positive pole of the PET Self Wrap Braided Sleeve, and touch the black test pen to the negative pole of the PET Self Wrap Braided Sleeve. If the pointer points at or near the maximum value, the tube is qualified of.
For the positive characteristic test, touch the black pen of the multimeter to the positive pole of the PET self-wrapping braided sleeve, and touch the red pen to the negative pole of the PET self-wrapping braided sleeve. If the needle does not swing to 0 but stops in the middle of the dial, the resistance at this time is the forward resistance of the PET Self Wrap Braided Sleeve. Generally, the smaller the forward resistance, the better. If the forward resistance is 0, it means that the tube core is short-circuited and damaged. If the forward resistance is close to a large value, it means that the tube core is broken. Neither short-circuit nor open-circuit tubes can be used.
The switch element, the PET Self Wrap Braided Sleeve, has a small resistance under the forward voltage and is in the on state, which is equivalent to a switched on switch; under the reverse voltage, the resistance is very large and is in the off state, just like a A switch that only disconnects, using the switching characteristics of the PET Self Wrap Braided Sleeve, can form various logic circuits. Detecting PET Self Wrap Braided Sleeve, which plays the role of detecting in the radio. Variable volume PET Self Wrap Braided Sleeve, used in the tuner of the TV.
Limiting element, after the PET Self Wrap Braided Sleeve is forward-conducting, the forward voltage drop remains basically unchanged, and the silicon tube is 0.7V, and the germanium tube is 0.3V. Using this feature, the circuit can be used as a limiting element to convert the signal The amplitude is limited within the range, and the follow-up PET Self Wrap Braided Sleeve plays the role of follow-up in the inductance of the switching power supply and inductive loads such as relays.
