How to use the voltage measurement method to judge whether the remote control is good or bad
The method of using the DC voltage range of the multimeter to judge whether the remote control is good or bad is simple and practical. The method is: remove the back cover of the remote control, turn on the power of the remote control, and use the multimeter to detect that the voltage at both ends of the infrared light-emitting diode is 0V or a certain value, and it is stable. Then any function controller of the Anton remote control, at this time, the voltage value of the multimeter immediately rises to a certain value or drops to 0V, and it is slightly shaking, which means that the remote control is good. For example, when the Fuli 3000 camera remote control is static, the voltage between the two pins of the infrared light-emitting diode is 0V. After pressing the function air file, it immediately rises to 0.25V and shakes slightly; while the Hitachi CEP-323D 18-inch color TV remote control, when static, the voltage between the two pins of the infrared light-emitting diode is stably pointed to 0.15V, and when dynamic, it immediately drops to 0V and shakes slightly.
If the voltage does not change between static and dynamic, or the voltage shakes when static, it means that there is a problem with the remote control.
