Introduction & Parts Identification
Flow Calibration Kit Setup
The AE51 Auto Flow Calibration software communicates with both the microAeth® AE51
and the external flowmeter included with the AethLabs Flow Calibration Kit.
In order to communicate with microAeth AE51, specific USB drivers are required. If you
have already installed the microAethCOM software for configuring and communicating
with the AE51, then these USB drivers are already installed on your computer. If this
is the first time using the microAeth AE51 with your computer then first install the
microAethCOM software.
1. Connect the barrel jack end of the AC
wall power adapter to the flowmeter.
Plug in the AC wall power adapter to an
electrical outlet.
Carefully unpack the flowmeter assembly and accessories:

3. Screw the 10-32 threaded elbow
fitting connected to the outlet port
of the flowmeter to the inlet port of
the microAeth AE51 (10-32 threaded
elbow fitting connected to 1/8” tube
WITHOUT the In-line 60mm round
ULPA Filter). On the rear panel,
opposite of the flowmeter LCD screen,
there is an arrow denoting the direction
of air flow through the flowmeter. Be
careful to ensure that the elbow
fitting o-ring face seal seats properly
against the AE51.

Auto Flow Calibration
11.Select the flow tolerance setting in the
Auto Calibration section.
1. Always make sure that a filter strip is
installed in the microAeth AE51 when
it is operating.
2. When exchanging a filter strip in the
microAeth AE51, make sure that it is
turned off.
3. Install a clean, unused filter strip into
the microAeth AE51. A pre-used filter
with heavy loading may create an offset
in the flow calibration table of the AE51.
9. Select the appropriate COM port from
the dropdown menu in the External
Flowmeter section of the software.
There may be multiple COM port
options depending on the computer
and the peripherals connected to it.
4. Make sure that the flow calibration kit is
connected to the AE51.
5. Connect the flowmeter and microAeth
AE51 to the computer with the software
installed.
6. Turn on the flowmeter and let it stabilize
for at least 10 minutes before use.
10.Click the Connect to Flowmeter button.
If the port is already in use, a window
will pop up to request that a different
port is selected. If the status bar at the
bottom of the software, does not show
‘microAeth ON, Flow Meter Connected’
status, check your connections and
ensure that communication with the
microAeth AE51 and flowmeter has
been initiated as previously described.
13.Click the View Instrument Values
button. This will display all the values of
the flow calibration table.
The sofware will attempt to calibrate
the internal flow system of the
microAeth AE51 with 1% of the
external flowmeter measurement. Some
instruments, especially older units that
have not had pump upgrade service
by AethLabs, may need to use the 3%
tolerance setting. Some instruments
may have internal pumps that cannot
reach the higher flow setpoints.
Instruments not sold by AethLabs may
require pump servicing by AethLabs
in order to achieve flow rates of 200
mlpm or higher. Contact AethLabs for
additional information.
12.Click the Calibrate button.
The system will automatically cycle
through all the setpoints of the flow
calibration table of the microAeth
AE51 (from 250 ml/min down to 0 ml/
min). The software will first check the
maximum achievable flow rate of the
instrument to determine what setpoints
can be calibrated. If the internal pump
cannot achieve the specified flow rate,
the setpoint will not be calibrated.
Contact AethLabs for a pump upgrade,
replacement, or service.
14.Please check the values to make
sure that as the flow setpoint
increases from 0 to 250 ml/min, the
pump drive and internal flowmeter
values also increase. If this is not the
case, please try again to calibrate the
microAeth AE51 using the auto and
manual flow calibrations. If this issue
persists, please contact AethLabs for
further assistance.
7. Turn on the microAeth AE51.
