3. Once power up is complete, press the Top line select and
Bottom line select keys to select the measurements to be
displayed. See Section 3.4, Measurements, for details on each
parameter.
You can change the display selections and connect or disconnect the
flow module or oxygen sensor at any time during normal operation.

If you disconnect the flow module, the controller module display
is blank.

If you disconnect the oxygen sensor, the sensor symbol and any
oxygen-related measurements are not shown on the display.

Normal operation and display resume about one second after
reconnection.
NOTE: The Certifier
®
FA Test System automatically updates
measurements that are recalculated at every breath. The Certifier
®
FA Test System uses a threshold flow to determine the beginning and
end of each breath. The threshold flow calculated from the last three
breaths, is updated at each breath, and then is applied to the
following breath. Breath measurement displays begin after two full
breaths.
CAUTION
To avoid damage to the Certifier
®
FA Test System components,
always use bacteria filters upstream of the flow modules, and always
cap flow module ports when not in use.
