Shopping Terms and Conditions:

All measuring instruments have measurement errors, and there are relevant national standards and international standards for electronic scales. The factory inspection standards of electronic scale manufacturers are carried out in accordance with these standards.

The general inspection of electronic scales includes precision testing, repeatability testing, corner deviation testing, moisture environment testing, uneven ground testing, etc. The general precision standard for household electronic scales is 0.3%+/-1d, where d is the minimum display gradation. The precision standard for body scales is 1%+/-1d. Any electronic scales within this standard are considered passable products.

If you need higher precision, please add one more precision digit on the basis of what you need. For example, if you need to be precise to 0.01 grams, rather than showing 0.01 grams, please purchase a product that shows 0.001 grams. Because in the standard of electronic scales, the last digit displayed is a reference value rather than the actual value. This is a standard industry regulation. Therefore, there will be differences in repeatability and four corner deviation (different positions of the weight on the scale plate) in the measured values, but it will not exceed ±0.03 grams, which is normal within the standard range.
