7.2 CALIBRATION VALIDITY
Calibration validity remains 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 will dictate shorter periods.
Regular calibration establishes a pattern of reliability and
enables the calibration check period to be modified in line with
operational experience. As a guide, the higher the risk, the
more frequently calibration should be checked.
