Changes in the external environment can have a direct impact on the weighing of the electronic scale. Changes in power supply, vibration, wind, and lightning can cause the electronic scale to be unstable. Wind and lightning are force majeure, and we can't avoid it. Therefore, we should try to avoid starting in high winds and thunderstorms. At the same time, the lightning protection measures and grounding protection of the electronic scale should be done. For vibration, measures such as cushioning devices, isolation grooves, etc. can be taken to reduce the influence. The power supply is not pure, and the method of separately wiring or adding a parameter regulator for the electronic scale can be adopted.
Fault example: For example, there is a DCS-2T electronic cylinder scale: the meter in operation often shows unstable values, irregular changes, and the range of variation is large, it can not be properly weighed, and occasionally it works normally. Careful observation at the site revealed an electric crane near the electronic platform. When the crane is working, the scale of the electronic scale is unstable, and the electronic scale is restored to normal after the crane is stopped. After checking the power supply circuit of the electronic scale, it was found that the electronic platform was connected to the crane on the same line, and the crane had great ripple interference when the crane was working.
Fault analysis: The displayed value changes from normal to normal. First suspect the power supply and external interference. Use a multimeter to observe the power supply voltage. Sometimes there are sudden fluctuations.
Troubleshooting: Separate the power supply of the electronic cylinder scale from the crane. Introduce a separate power supply for the electronic platform. Troubleshooting.
Electronic scale scale external factor fault handling method
Electronic scales are common weighing scales used by various industrial and commercial businesses. After using it for a long time, it will inevitably encounter some faults. So what should we do when there is a problem with the electronic scale? First of all, it should be based on the principle of first and foremost. After the electronic scale fails, the influence of external factors should be excluded first.
