1. Calibration
FIGURE 5-9 Connecting the Flow Analyzer
a. Connect one end of the Respiration Tube to the Common Gas Outlet on the
AS3000, and the other to the inlet on the Flow Analyzer (Certifier-FA PLUS).
b. Set the Fresh Gas flow to 0 mL/min.
c. Select Continue to start calibration.
d. Ensure that there is 0 flow on the Flow Analyzer.
e. Set the on screen calibration to 0, and select Done to begin calibration. Successful
calibration will be confirmed by illuminating the corresponding calibration value
yellow. If the calibration value illuminates red, recalibrate the value until it
successfully calibrated.
f. Set the onscreen calibration value to 1.
g. Raise the flow until it reads 1.00 on the Flow Analyzer using the Flow Meter.
h. Select Done to begin calibration.
i. Repeat steps f. through h. for all calibration values listed on the screen. Ensure all
successfully calibrate and illuminate yellow.
j. After all values are successfully calibrated select Finish Cal.
k. The AS3000 will confirm that calibration was successfully completed.
l. Select Done to return to the calibration screen.
NOTE: When calibrating the Flow Meter, use AIR if available,
otherwise use a combination of O
2
and N
2
O to attain a flow
of 15 L/min.
