28. Once again, use the flow control valve to set the negative flows that the program requests
and enter the values.
29. The program has now completed calibrating the flow and pressure sensor.
30. The program will now ask for the barometric pressure reading. Using your barometer
enter the value in iniches.

31. Pressure and flow accuracy of the device must now be verified. The program will now
read the pressure and flow parameters from the device and compare these reading to the
pressure and flow values that the user will enter.
32. The program will first verify positive flows. Turn off the negative flow source and discon-
nect the patient tubing from between the negative flow source and the flow valve. Com-
pletely open the flow valve. Follow the prompts on the screen for the flow settings.
