2. If present, disconnect the mainstream sensor from the monitor.
3. If installed, remove the water tap from the receiver on the front left panel of the
expansion module.
4. Determine the local barometric pressure as instructed in
preparation"
5. Select the SIDE TST screen through SETUP > MORE > MORE > SERVICE > YES >
CO2 TEST.
6. Verify that BARO TRUE and INT are within 15 mmHg (5 mmHg, 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.
Pressure meter
8. Use the pump bulb to manually inflate the pressure to 100 mmHg 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 10
mmHg. (Replace the water trap and retest if the leak rate is over 10 mmHg.) 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
