14.1 CALIBRATION VALIDITY
Calibration validity is the responsibility of the user. Under normal
operating conditions a 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 period to be modied in line with operational
experience. The higher the risk, the more frequently calibration
should be checked.
