Note the flowrate.
9 Block the Anesthetic Gas Module exhaust (using your finger tip).
10 Check the effect of blocking the exhaust.
The reading at the flowmeter should decrease to Zero (see Table 4-1). If it does not, systematically
block the pneumatic path at various points after the pump to isolate the leakage point. (See Figure
1-2, "Pneumatic System" for tubing connections.) When the fault has been corrected, repeat the
leakage check.
Performance Diagnostic Check
Complete the following to do a performance diagnostic check:
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 Make sure that the watertrap is attached.
3 In the Setup Gas Analyzer menu select Service Window then select Diagnostic to
access the
Gas Analyzer Diagnostic window.
4 Check that no permanent problems are reported for the Philips M1026A Anesthetic Gas Module
in the
Gas Analyzer Diagnostic window.
Performance Flowrate Check
Always perform a leakage check before the flowrate check. Three flowrates need to be checked in the
following order:
1 To t a l f l o w i n Purge mode.
2 Flow in Measurement Path in Normal mode.
3 To t a l f l o w i n Normal mode.
These flowrate checks are described in the following three procedures.
The total flow is measured by connecting the flowmeter to the exhaust, the measurement path flow is
measured by connecting the flowmeter to the gas inlet with a special test fixture.
The Flowrate values are summarized in the following table:
NOTE Do not perform the flowrate check while a Zero calibration is running.
Items Value / Tolerance
Leakage Range: 0 → 4 ml/min
Total Flowrate Value
Purge 310 ml/min
Normal 150 ml/min
