5.8.3.4. Filter Tape Cartridge Removal and Installation
The on-board user interface on the front of the microAeth is used to remove and install the filter tape
cartridge.
1) Make sure that the microAeth is not sampling. If the instrument is sampling, use the on-board interface
to stop sampling and measurements.
2) Unscrew the large flat head slotted screw(s) in the filter tape cartridge door of the case. When the
screw is completely free of its mating threaded hole, use the flat head slotted screw(s) to pull the filter
tape cartridge door from the case.
3) The filter tape cartridge will now be exposed or if a filter tape cartridge is not currently installed, the
cartridge holder area will be empty.
4) Use the left and right buttons of the on-board user interface to scroll through the top level menu
options to 'Release Tape'.
5) Press the center button to select the 'Release Tape' option. The optical head of the instrument will
move to its open position and stop in about 6 seconds.
6) Once the optical head stops moving, use the pull tab in the center of the filter tape cartridge to remove
the cartridge straight out of the instrument.
7) Insert a new filter tape cartridge straight into the instrument, aligning the left and right holes in the
cartridge with the two white capstans in the instrument.
8) Make sure that the new filter tape cartridge is fully inserted and sits flat in the instrument.
9) Use the left and right buttons of the on-board user interface to scroll through the top level menu
options to 'Clamp Tape'.
10) Press the center button to select the 'Clamp Tape' option. The optical head of the instrument will
move to its clamped position and stop in about 6 seconds.
11) Confirm that the filter tape cartridge is clamped by the optical head.
12) If the filter tape cartridge is correctly installed, replace the filter tape cartridge door to its closed
position and completely screw the large flat head slotted screw(s) in place. Once the door is in its closed
and locked position, the instrument is ready for further use
13) If the filter tape cartridge is not fully installed or seated properly in the instrument after clamping the
tape, use the left and right buttons to scroll through the top level menu options to 'Release Tape'. Press
the center button to select the 'Release Tape' option. If the instrument does not accept the release tape
command, press and hold down the center button until the optical head moves up enough to remove the
filter tape cartridge. Then remove the filter tape cartridge. Use the left and right buttons to scroll through
the top level menu options to 'Clamp Tape'. Press the center button to select the 'Clamp Tape' option.
The optical head of the instrument will move to its clamped position and stop, resetting the optical head
position. Go to step 4 and try again to replace the filter tape cartridge.
5.8.3.5. Calibrate Flow
Please read section 7.2. Flow Calibration Table and section 7.3. Flow Calibration Procedure before
using this menu option. The only way to perform a flow calibration on the MA200, MA300, and MA350 is
to use a microAeth MA Series Flow Calibration Kit provided by AethLabs.

5.8.3.6. Display All Settings (terminal emulator interface only)
The on-board user interface on the front of the microAeth is used to send all settings information of the
instrument via the 4-pin serial port. Displaying all settings of the microAeth can be accomplished through
the serial port to a terminal emulator on a computer using the AethLabs 4-pin Serial to USB converter
cable.
Before using the AethLabs 4-pin Serial to USB converter cable, it may be required to install drivers
from Future Technology Devices International Ltd. (FTDI) in order for the converter cable to be
recognized by and used with the computer.
1) Unplug the microAeth from all external power sources.
2) Plug in the AethLabs Serial to USB converter cable to the 4-pin serial port of the microAeth. Plug in the
USB A plug of the cable into a computer where data will be download.
3) Open a terminal emulator (TeraTerm for Windows is highly recommended) on the computer and use the
following settings (as described in section 5.5.3):
4) The terminal emulator should now display the on-board user interface options as the 3 button interface
is used by the user. More information that is hidden on the microAeth on-board screen will be displayed in
the terminal emulator.
5) Use the left and right buttons to scroll through the top level menu options to the 'Display All Settings'
option.
6) Press the center button to select the 'Display All Settings' option.
7) All settings and status information will be displayed in the terminal emulator.
5.8.3.7. Turn Off
The on-board user interface on the front of the microAeth can be used to turn off the instrument.
1) Use the left and right buttons to scroll through the top level menu options to 'Turn Off'.
2) Press the center button to select the 'Turn Off' option. The screen and instrument will turn off.
