5.2 CALIBRATION VALIDITY
Calibration validity is the responsibility of the user. Under
normal operating conditions a 6 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.
