6. Verify that BARO TRUE and INT are within 15mmHg (5mmHg, typical) of the
barometric pressure determined in step 4.
7. Connect the test tubing setup shown in the figure below to both ends of a test water
trap.
8. Use the pump bulb to manually inflate the pressure to 100mmHg as read on the
pressure meter.
9. Wait 15 seconds for the pressure to stabilize. Note the pressure reading, then wait an
additional 60 seconds and check that the pressure has not dropped more than
10mmHg. (Replace the water trap and retest if the leak rate is over 10mmHg.) Record
the leak rate value for use in step 17 below.
10. Disconnect the water trap from the test setup and install it into the water trap
receiver of the monitor under test. Wait for SRCH to appear in the SCO
2
numerics
window.
11. Plug the water trap inlet and verify that the monitor generates an OCCLUSION-
CHECK WATER TRAP/TUBING equipment alert message. Acknowledge the
equipment alert. Wait for SRCH to appear in the SCO
2
numerics window.
12. Plug the exhaust port and verify that the monitor generates an OCCLUSION-CHECK
EXHAUST PORT/TUBING equipment alert message. Acknowledge the equipment
alert.
13. Through the CO

14. Connect the test tubing setup (step 7 on page 31) to the water trap inlet and to the
exhaust port.
Caution The occlusion test can stress any defective pneumatic tubing
connections and may cause leakage. Always perform the following leak test after
the occlusion test to reveal any tubing problems.
