Many people might wonder if calibrating scales once a year… is enough?

Many organizations set the calibration cycle at once a year because it is a long-standing practice that seems reasonable overall. However, based on the real field experience of the TMC team, the answer is that annual calibration is not the only answer for every instrument.

Instruments that are used occasionally but are in a well-controlled environment may be suitable for annual calibration. In contrast, instruments in production lines that are used continuously or affect quality-related decisions are higher risk and should be calibrated more than once a year.

On calibration days (Audit), auditors usually do not just check whether the instrument's calibration is still valid; they are interested in whether the scheduled calibration cycle aligns with actual usage.

Therefore, the important thing is not the number of times per year, but rather setting a calibration schedule that is appropriate for the risk level of each device.
