How to debug the weighbridge display weighing numbers? When you are using the electronic scale, has there been any phenomenon that the number on the electronic scale will jump, then you know what is going on? Kunming scales know that the following reasons will cause the electronic scale to jump, you Which is it? First, the power supply voltage is unstable. If the power supply is not added, it will exceed the normal working voltage range of the instrument, and there will be a digital jump phenomenon, so configure a regulated power supply. Second, the junction box is not well sealed, the humidity inside the box is too large. Open the junction box to see if there is water or moisture, and dry it or blow it dry with a hair dryer. The fault can be eliminated. Replace the junction box if necessary. Third, the main scale of the weighbridge is damaged. Some scales are too far from the meter , and the main line has exposed parts. It may be damaged by humans or rat bites. The metal shield loses its function or the connection is not strong, causing digital jump. The multimeter resistance file measures the main line to ensure that each strand is an independent channel, and the connection is firm, otherwise the main line is replaced. 4. The circuit board inside the junction box is damaged. The long-term use of the terminal can cause oxidation and corrosion, and the oxidation and corrosion of the joint will fall off, causing the pressure line to loosen, thus causing the digital jump of the meter. At this time, the contact surface can be rubbed off with a sandpaper or a file. Reconnect is firm and the fault phenomenon is eliminated. Long-term use of multi-turn resistors can also cause the internal metal surface to be oxidized, which makes the digital unstable and jump. At this time, the fault can be eliminated by replacing the multi-turn resistor with the same resistance. How to debug the weighbridge display weighing numbers? 5. Plug or socket oxidation. Long-term use of the instrument and the main line plug or socket may also cause oxidation, making the connection resistance unstable. The method is to soak the plug or socket with 10% dilute hydrochloric acid for ten minutes, then blow dry or dry with a hair dryer. , or replace it (Note: the soldering iron should be as hot as possible when replacing, once soldered, not used in the soldering station to avoid oxidation of the solder). 6. The electronic pound sensor is damaged or drifted. When the sensor is damaged or drifts, the digital jump may also be unstable. Under normal circumstances, one sensor drifts or is damaged. To determine which one is only faulty, you can use the method of directly connecting the main line. That is, remove all the sensor wirings until one is left, then connect the sensors one by one, and observe whether the meter display is normal, you can judge the damaged sensor. Replace it to solve the problem. 7. The foundation of the weighbridge is not strong. During long-term use, the impact or overload of some vehicles may cause the sensor to be overstressed, causing the foundation to loosen, making the level between various sensors.
