What should I do if there is an error in the newly purchased scale in Xiamen?

What should I do if the newly purchased electronic scale is not accurate? There are usually the following aspects.
Because it is a newly purchased electronic scale, there may be an issue with the setup. Most new scales come with protective screws. Mainly for the protection of electronic scales during transportation. Protect the sensor of the electronic scale from damage. Just dismantle it!
1. Pick up the scale pan
2. You will see several screws on the electronic scale between the scale frame and the sensor, usually one on each corner, for a total of four screws. These four screws are called protective screws, which are used to protect the sensor from damage during transportation.
3. Remove or tighten the protective screws that protect the electronic scale sensor during transportation, leaving some gaps between the scale frame and the protective screws.
4. After removing or fully tightening the protective screws, the electronic scale can be used normally without inaccurate weighing.
We usually encounter more problems like this. If it's not this issue, or if the seller didn't even install protective screws, then it's possible that they were damaged during transportation. There are usually damaged areas.
a. If the electronic scale instrument can display normally, there is generally no problem.
b. The electronic scale sensor, if the weighing data is always not fixed and there is a large difference between it and the actual weight, it may be faulty.
c. If there is not much difference in the weighing data of the electronic scale body, it is also possible that the scale frame is deformed.
d. The four legs of the electronic scale must be leveled and not overloaded
