Gas Monitor Calibration - Passport 2
Accuracy verification of the Gas Module 3 is recommended at one (1) year intervals or
whenever gas readings appear to be in error.
The date of the last successful mixture calibration appears at the bottom of the gas
Calibration Menu. During the calibration session gas readings and all other gas functions
are not available.
Span calibration is a set of prompted commands that enables the operator to align the gas
display(s) to specific gas concentration(s) within the Mindray DS Calibration Gas canister.
Span calibration can be initiated by the operator any time the gas module's readings are
suspected to be inaccurate.
Always verify accuracy using a full canister of Mindray DS approved precision calibration
gas, after calibration is performed. Never use calibration gas that has expired, has a
different concentration, or a canister that is indicating low pressure. The pressure indicator
on the Mindray DS gas regulator must operate in the green zone during the entire calibration
session.
NOTE: The Gas Module 3 must be fully warmed up before
performing a gas calibration. For maximum accuracy, a
warm-up time of 10 minutes is recommended.
