FIGURE 5-4 Connecting the Vent Tester to the AS3000
a. Connect one end of the Calibration Hose to the High Pressure port on the AS3000
and the other to the inlet on the Vent Tester.
b. Connect one end of the Respiration Tube to the expiratory port on the AS3000 and
the other to the outlet of the Vent Tester.
c. Connect an unterminated tube (at least 1 meter long) to the inspiratory port on the
AS3000.
d. Select Continue to start calibration.
e. Ensure that there is 0 flow on the Flow Analyzer.
f. 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.
g. Set the onscreen calibration value to 1.
h. Raise the flow until it reads 1.00 on the Flow Analyzer using the calibration hose
valve.
i. Select Done to begin calibration.
j. Repeat steps g. through i. for all calibration values listed on the screen. Ensure all
successfully calibrate and illuminate yellow.
k. After all values are successfully calibrated select Finish Cal.
