7.3.2.2. Flow Calibration Table Example
Below is an example of a flow calibration table that will be displayed using the Display All Settings or
Display FlowCal Info menu items. The values in the flow calibration table can be analyzed and verified in
order to determine if another flow calibration is required. If multiple flow calibrations have been performed
and still there are issues, please contact AethLabs.

7.3.3. Test Flow Procedure
The on-board user interface on the front of the microAeth can be used to test flow setpoints and see what
the internal flowmeters are reading in DualSpot or SingleSpot mode.
Please note that the external flowmeter
of the microAeth MA Series Flow Calibration Kit or other low backpressure external flowmeter is not needed
to use this feature but is needed to verify the internal measured flow readings against an external standard.
1) If checking the internal measured flow of the microAeth to an external standard, connect the outlet port
of the external flowmeter to the inlet port of the microAeth.
2) Make sure that all connections are tight and sealed so that no leaks are present.
3) Use the left and right buttons of the microAeth to scroll through the top level menu options to the 'Test
Flow' option.
4) Press the center button of the microAeth to select the ‘Test Flow’ option.
5) Use the left and right buttons of the microAeth to scroll to the desired target flow of 50, 75, 100, 125, or
150 ml/min. The screen will display the following depending if the microAeth is in SingleSpot or DualSpot
mode:
SingleSpot Mode Test Flow Display DualSpot Mode Test Flow Display
SS Target xxx.xx DS Target xxx.xx
SS Measured xxx.xx DS Measured xxx.xx
NOTE: To use the test flow feature in the desired SingleSpot or DualSpot mode, this sampling mode setting
must first be changed using the microAeth Manager software connected to the microAeth by USB.
6) Use the left and right buttons to change the target flow at any time. Allow the microAeth a few seconds
to adjust pump speed and for the flow to become stable.
7) The measured flow can be viewed over time as there will be fluctuations. The measured flow can also
be compared against the external flowmeter of the MA Series Flow calibration Kit that has its outlet port
connected to the inlet port of the microAeth. Only compatible low backpressure external flowmeters should
be used.
8) Press the center button to exit the test flow feature.
