Calibration of mass standards like the Ohaus 42740 1g and 5g weights is typically recommended once a year (annually) in environments requiring high accuracy. However, the frequency can vary depending on usage, environment, and institutional procedures—some may opt for every 6 months in rigorous quality-controlled environments.
