10. Check the proportioning system concentration (decreasing O
2
flow). Observe the following precautions:
• Start with the N
2
O valve at the maximum setting.
• Adjust only the O
2
flow control.
• Decrease the O
2
flow as specified in the table and make sure
the O
2
concentration is in the allowed range.
Note: Allow the O
2
monitor to stabilize. At the lower flows, the
O
2
monitor may take up to 90 seconds to stabilize.
• If you overshoot a setting, turn the N
2
O flow control
counterclockwise until the O
2
flow increases to the previous
setting before continuing the test.
3.4.2 Without O
2
monitoring
WARNING The following procedure will test for any significant
malfunction of the Link system but it will not confirm
proper calibration.
Nitrous oxide (N
2
O) flows through the system during this
test. Use a safe and approved procedure to collect and
remove it.
1. Set up the gas scavenging system.
• Attach a patient circuit and plug the patient port.
• Attach a bag to the bag port (or plug the bag port).
• Adjust the APL valve to minimum.
2. Connect the pipeline supplies or slowly open the cylinder valves.
3. Turn all flow controls full clockwise (zero flow).
4. If equipped, set the ACGO selector switch to Breathing System.
