Calibration Validity
Calibration validity is the responsibility of the user. Under normal operating conditions 12 month
period can be expected. This is no guarantee, however, as the precise application of the product
is unknown to GMI. Individual codes of practice may dictate shorter periods.
Regular checking establishes a pattern of reliability and enables the calibration check to be modifi ed
in line with operational experience. The higher the risk, the more frequently the calibration should
be checked.
