The frequency of calibration depends on several factors, including the type of equipment, the manufacturer's recommendations, the frequency of use, and the criticality of the measurements. Generally, equipment should be calibrated at regular intervals, such as monthly, quarterly, or annually. In some cases, daily checks or calibrations are necessary, especially for equipment that experiences heavy use or is involved in critical analyses. Keeping a detailed calibration schedule helps ensure that all equipment is calibrated appropriately.
