What should I do if the electronic platform has a hop count?
Electronic weighbridges are easy to understand. To put it bluntly, it is a mechanical device that uses modern devices to measure the weight of objects with high technology. Electronic scales can be divided into different types according to different principles. Of course, each type is applicable to different environments according to functions. Generally speaking, it belongs to electronic scales because it can ensure mechanical functions to a large extent. The operation. But what should I do when the electronic platform has a hop count problem? The following is an introduction to the analysis and troubleshooting of the electronic scales by the Eagle Weighing Apparatus:
The junction box is not well sealed and the humidity inside the box is too large:
Open the junction box to see if there is water or moisture. If it is aired or blown dry with a hair dryer, the fault can be eliminated. Replace the junction box if necessary.
The power supply voltage is unstable:
The input voltage range of the electronic platform meter is (210~242)V. Some units do not add the regulated power supply, which causes the normal working voltage range of the instrument to exceed the digital jump phenomenon. Therefore, a stable power supply is configured.
Damage to the board inside the junction box:
The circuit board inside the junction box consists of a terminal block and several sets of multi-turn resistors. Long-term use of the terminal can cause oxidative corrosion, and the oxidized rust part of the joint falls off, causing the pressure line to loosen, thereby causing the meter to jump digitally. At this time, the contact surface can be rubbed off with a sandpaper or a trowel, and the connection is firm again, and the malfunction is eliminated. Long-term use of multi-turn resistors can also cause the internal metal surface to be oxidized, making the digital unstable and hopping. In this case, the fault can be eliminated by replacing the multi-turn resistor of the same resistance.
Electronic floor scale main line damage:
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 is not functioning or the connection is not strong, causing digital jumps. Measure the main line with a multimeter resistance file to ensure that each strand is an independent channel and that the wiring is secure, otherwise the main line is replaced.
Plug or socket oxidation:
Prolonged use of the meter and mains 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 welded, not at the weld. Use it multiple times to prevent the solder from being oxidized).
Electronic platform foundation loose:
During long-term use, the impact or overload of some vehicles may cause the sensor to be overstressed, causing the foundation to loosen, causing the level of damage between the various sensors, resulting in digital jumps. In this case, you need to re-solidify the foundation and find a good level.
Electronic floor scale sensor damage, drift:
When the sensor is damaged or drifts, the digital jump can also be unstable. In general, one sensor drifts or is damaged. To determine which one is the only fault, you can use the method of directly connecting to the main line. That is, all the sensor wirings are removed one by one until one is left, and then the sensors are connected one by one, and the meter is displayed to be normal, the damaged sensor can be judged, and the replacement can be solved.
The above is a detailed explanation about how to do the volley of electronic scales, I hope to help everyone. The predecessor of Eagle Scale Weapons - Shanghai Weighing Apparatus Factory was founded in 1917. It is a professional manufacturer and manufacturer of scales, truck scales and electronic scales.
