7.3.2.2. Flow Calibration Table Example
Below is an example of a ow calibration table that will be displayed using the Display All Settings or
Display FlowCal Info menu items. The values in the ow calibration table can be analyzed and veried in
order to determine if another ow calibration is required. If multiple ow 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 ow setpoints and see what
the internal owmeters are reading in DualSpot or SingleSpot mode. Please note that the external owmeter
of the microAeth MA Series Flow Calibration Kit or other low backpressure external owmeter is not needed
to use this feature but is needed to verify the internal measured ow readings against an external standard.
1) If checking the internal measured ow of the microAeth to an external standard, connect the outlet port
of the external owmeter 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 ow 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 ow feature in the desired SingleSpot or DualSpot mode, this sampling mode setting
must rst be changed using the microAeth Manager software connected to the microAeth by USB.
6) Use the left and right buttons to change the target ow at any time. Allow the microAeth a few seconds
to adjust pump speed and for the ow to become stable.
7) The measured ow can be viewed over time as there will be uctuations. The measured ow can also
be compared against the external owmeter 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 owmeters should
be used.
8) Press the center button to exit the test ow feature.
