3. Turn on the Gas Module and Passport XG, and configure the Passport XG to be used
with the Gas Module. Set alarms as desired.
NOTE: Refer to “User Configuration - Serial Output Type Menu” on
page 1-188, “Gas Module Menu” on page 1-182 and
“Alarm Limits” on page 1-150.
4. Check for a clean water trap. If cleaning is necessary, “Safety Precautions” on page 4-1
for details.
5.
Select CO

Observe the capnogram on the monitor’s display. When the Passport XG has detected
valid breaths, numbers will display for CO

O readings and five
minutes for agent readings.
7.
If not already set, use the Setup Menu, to select “Auto Display CO

displayed on Waveform 2 or Waveform 3.
8. If desired, the Gases waveform scale and speed can be changed by entering the Gases
menu. See “Use of Menus” on page 1-109 for details.

1.6.14.2 Gas Monitor Calibration
Accuracy verification of the Gas Module is recommended at six (6) month intervals or
whenever gas readings appear to be in error. The date of the last successful mixture
calibration appears at the bottom of the “Gases” menu. The operator may elect to perform a
Zero calibration (lasting approximately 10 seconds) or a Span calibration (lasting
approximately 2 minutes) at any time. During the calibration session gas readings and all
other gas functions are not available.
Zero calibration is a single action command that compensates all gas channels for the effects
of offset drift. Zero calibration may be performed on command and also takes place
automatically at preset intervals. To manually perform a Zero cal, choose ‘YES’ from the Zero
calibration gas menu (refer to “Gas Module Menu” on page 1-182).
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 Datascope Calibration Gas canister.
Span calibration can be initiated by the operator any time the gas module’s readings are
suspected to be inaccurate. Span calibration should be performed if after performing a Zero
cal, the gas readings do not display the accurate valves.
Always verify accuracy using a full canister of Datascope 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 Datascope gas regulator must operate in the green zone during the entire calibration
session.
