Flowrate
Calibration
11 If you have made adjustments you must save the settings. Therefore select Store Flow Cal and
confirm when prompted.
The system then runs through various flowrates and switches the pump off before it saves the
values internally.
12 Disconnect the flowmeter from the test-fixture.
13 Replace test-fixture with watertrap
Total Flowrate Check in Normal Mode
To make the flowrate measurements and any necessary adjustment:
1 Enter the service mode of the monitor and let the Philips M1026A Anesthetic Gas Module
complete the warm-up phase (the
GA WARMUP INOP disapears).
2 Enter the Setup Gas Analyzer menu and select Start Flow Cal.
3 Select Flow Rate.
4 Select Normal for normal flow (150 ml/min).
5 Connect a flowmeter to the exhaust port of the Philips M1026A Anesthetic Gas Module.
Check 6 Note the actual flowrate by following the instructions accompanying the flowmeter. If the actual
flowrate is outside the tolerance, check all tubing for occlusions (for example kinks, dirt) and
replace if necessary. Repeat flowrate check. If the flowrate is still no within tolerance, exchange the
Nafion tubing, bacterial filters and restrictor in the drainage path (provided with the Internal
Tubing Kit and the Preventive Maintenance Kit) before repeating flowrate check.
If no adjustments are required, select
Stop Flow Cal.
7 Disconnect the flowmeter from the exhaust port.
Zero Calibration
NOTE Only perform a zero calibration with the top cover closed. Light and electro-magnetic interference may
affect the measurements. Zero calibration is not possible during warm-up.
