How to protect the "weighing display"? Tell you how to maintain the “weighing monitor”?

Any weighing needs a scale body and a display. Many, electronic scales and electronic scales have a wide range of measurement ranges. Due to long-term use, it may cause problems with the display of electronic scales. Then we are using it in daily use. How to properly protect it?

1. Anti-static: Once the meter is damaged, it needs to be repaired. In order to accelerate the speed of round-trip transmission, some units of electronic truck scales like to remove the PCB board of the meter and send it by express mail, which creates an anti-static problem. .When taking the PCB board, hold the four corners of the board, do not touch the place with the integrated block pins. Because it is easy to damage the integrated block by static electricity. The removed PCB board should be immediately put into the shielding bag, without shielding In the case of a bag, you can wrap it with ordinary newspaper. If you place the board on a high-insulation desktop, you may damage the PCB. When you receive the repaired PCB and need to reinstall it, you should also pay attention to anti-static. .

2. Installation: Generally, the instrument should be placed in a clean, dry, ventilated, and temperature-appropriate environment. The position of the instrument should be fixed and not moved frequently, otherwise it may cause the internal leads of the signal cable plug to fall off and cause malfunctions.

3. Sun protection: Avoid direct sunlight on the black shell of the instrument, otherwise it may damage the instrument's working environment beyond the rated temperature range.

4. Waterproof: In general, although the humidity of the working environment of the instrument can reach 95%, it is stipulated that condensation cannot occur. Except for special stainless steel shell instruments with waterproof function.

5. Corrosion resistance: Corrosive substances cannot penetrate into the instrument, otherwise it will corrode the components on the circuit board and the circuit board itself. Over a long period of time, the instrument may be scrapped. Even if the instrument has anti-corrosion function, if it is not tightly closed And will have the same result.

6. Lightning protection: The electronic weighing instrument belongs to the weak current system and is easy to be damaged by lightning strikes. The lightning mainly enters the instrument from two aspects: imported by the power cord and imported by the weighing platform through the signal cable. Under normal weather, the operator As long as the power switch is operated, but in the case of a short-range lightning strike, you must unplug the power plug of the instrument and the signal cable plug of the weighing platform. It is best to take anti-lightning measures, such as adding anti-surge protection in the instrument power circuit Device etc.

7.Anti-strong electricity: The live wire of the power supply above 220 volts accidentally hits the weighing platform or uses the weighing platform as the ground wire, and the welding operation on the weighing platform may damage the instrument.

8. Cleaning: In the industrial environment, there will be dust or contamination on the instrument shell, and it must be cleaned frequently with a wet rag when the power is turned off. But be careful not to wipe the display window with alcohol and other solvents, which will cause light transmission The performance deteriorates and the display is blurred.
