Calibrating
NOTE: Ensure that the calibration gas and regulator are functioning properly before
calibration. Perform annual maintenance of the regulator as required.
NOTE: Do not wash or disinfect calibration gas sampling lines.
The airway module should be calibrated once every six months or whenever there are
indications of errors in the gas readings.
Calibrate the gas measurement with the GE Healthcare calibration gas. Do not use any other
calibration gases.
− Use the regulator 755534 or equivalent.
− Use the gas 755580 only and set the CO
2
concentration to 20%.
If you do not use the recommended calibration gases, the calibration does not succeed.
During gas calibration, % units are always used for CO
2
regardless of selected measuring units.
Figure 17-5 Attaching regulator to calibration can
1. Attach the regulator to the gas container.
2. Attach a new sampling line to the water trap. Connect the loose end of the sampling line
to the regulator on the gas container.
