Calibrating
Perform calibration every six months in normal use, once every two months in continuous use,
and whenever there are indications of errors in the gas readings to ensure that the
measurement accuracy remains within specifications.
Calibration setup
Required tools

NOTE: Use only the specified GE Healthcare calibration gas for the gas calibration to
ensure measurement accuracy. Do not use any other calibration gases. Check the
calibration gas container's labelling to ensure that the calibration gas has not expired.
NOTE: Ensure that the gas regulator is functioning properly before gas calibration.
Refer to the gas regulator's "Instructions for Use" letter for the annual maintenance
instructions.
Connections
1. Ensure that the module is connected to the monitor.
2. Ensure that you have a new D-fend or D-fend Pro water trap in use.
3. Connect the gas regulator to the calibration gas container.

4. Connect a new gas sampling line to the sampling line connector in the water trap.
5. Connect the other end of the gas sampling line to the regulator on the gas container.
Leave the regulator overflow port open to room air.
