Accuracy
Your scale comes calibrated from the factory and most
users won’t need to calibrate their scale for a long time.
You should check your scale’s accuracy periodically using
calibration weights and perform calibration if necessary.
NOTE: Only use trusted calibration weights.
Household items such as bottles and cans with
weights printed on the side are not suitable for
checking accuracy as these values are approximate
and don’t include the container weight (Net Weight).
