The calibration must be effected in an environment free of vibrations and drafts. You must have a proper calibration weight, with an error less than

0.1 g (we recommend using calibration weights Class M2 OIML R-111 or superior).

The model AC-500 is calibrated with a weight of 500 g and the model AC-5000 with a weight of 5.000 g.

To calibrate the scale, please follow the following steps:
