Type and common pole time of LED digital tube
When detecting the segment corresponding to each pin of the multi digit LED nixie tube, the multimeter selects the R * 10K gear. For the common anode nixie tube, the black lead is connected to the common electrode of a certain position, and the red lead is connected to its pin. If the nixie tube returns a weak bright light, such as the bright light in segment a, it indicates that the pin connected to the red lead is connected to the negative electrode of segment a LED. For the common cathode nixie tube, the red lead is connected to the common electrode of a position, and the black lead is connected to other pins, If a weak light is found on a segment of the nixie tube, the pin of the black probe is connected to the positive pole of the LED segment.

How to judge whether the LED is broken inside
Speaking of LED digital tube, I think everyone should be familiar with it. It is an electronic device that can display numbers and other information. Display numbers are often used in modeling, and the method is simple. Many feet feel bad and it is not convenient to control them directly with your hands. There are also professional decoders, but the number of pairs has increased. Today, let's talk about how to use nixie tube. Look at the internal schematic first. It can be seen from the following two figures that the inside of the nixie tube is composed of many light emitting diodes (LEDs). Because leds have positive and negative electrodes, nixie tubes can be divided into two types, one is a common cathode, the other is a common anode. The so-called common cathode refers to connecting the negative electrodes of all light-emitting diodes together, and the common anode refers to connecting the positive electrodes of all light-emitting diodes together.
