7. Maintenance and Service
7.1. Cleaning
If the microAeth is exposed to any liquids or other damaging contaminants, immediately turn off the
instrument, disconnect all cables, and remove any foreign substances in contact with the instrument.
Do not use liquids or other cleaning products on the instrument. Wait until the microAeth is completely
dry before charging or turning on the instrument. Only AethLabs authorized service personnel should
clean the air passageways and internal components of the microAeth. Keeping the microAeth and its air
passageways, internal components, and optical chambers clean is critical for maintaining the instrument
and producing quality measurements. Contamination of the instrument can cause increased measurement
noise, poor sealing of the analytical area and degraded operational lifetime of some components.
AethLabs
recommends sending your instrument for annual service, or more frequent service depending on use
and operating conditions.
7.2. Display and Check All Settings
The Display All Settings menu outputs all the current settings and status information of the microAeth via the
4-pin serial port to a terminal emulator (AethLabs only supports Tera Term for Windows) on a computer using
the AethLabs 4-pin Serial to USB converter cable.
To view all settings, the on-board user interface on the front of the microAeth is used to send all settings
information of the instrument which includes the flow calibration table (See section 5.8.3.11. Display All
Settings).
Below are descriptions of all the settings and is an example of a settings table that will be displayed using
the Display All Settings menu item. The values in the settings table can be analyzed and verified in order to
determine the current state of the instrument.
7.2.1. Display All Settings Descriptions
The display all settings menu transmits via the serial port a complete summary of all settings and status of
the microAeth.
Setting / Status Format Example Description
Manufacturer Alphanumeric AethLabs
Serial Number
Model and number
(MAxxx-xxxx)
MA200-0011 Unique identification number for the Instrument.
Firmware Version Decimal number 1.08
Unique identification number for firmware running
on instrument when measurement was recorded.
Name Alphanumeric MA Device
User editable device name through microAeth
Manager.
Timezone Offset Minutes (Integer) -480
Timezone offset from Coordinated Universal Time
(UTC) in minutes.
Flow
Milliliters per minute
(Whole number)
100
Target setpoint value of the instrument total flow
rate in milliliters per minute. Used in SingleSpot™
and DualSpot® sampling modes.
Timebase
Seconds
(Natural number)
60
Value in seconds of the measurement interval
between measurements.
Tape Advance ATN
Attenuation units
(Natural number,
1-100)
50
Tape advance ATN threshold value will trigger an
automatic tape advance to a new filter sampling
location during a sampling and measurement
period. The attenuation (ATN) threshold value
will trigger a tape advance when the first of the
wavelength measurements reaches this threshold.
NOTE: The lowest wavelength light source
enabled will typically trigger the attenuation (ATN)
tape advance.
Tape Advance Time 0 00:00:00.000Z Not available in current firmware.
Tape Advance Intv Two (2) Whole numbers 0 1 Not available in current firmware.
AutoSample Whole number 0
Value of setting to automatically start sampling
and measurements.
DualSpot Whole number 1 DualSpot mode on or off.
GPS Two (2) Whole numbers 1 1 Value of GPS setting.
GPS Time Sync Whole number 1 GPS time sync on or off.
Bluetooth Enabled Whole number 0 Not available in current firmware.
Serial Mode Whole number 1 Value of serial mode.
Serial Format Whole number 0 Value of serial format.
Serial Baud
Whole number with
corresponding baud
rate value
5 (1000000) Value of serial baud rate.
Wavelengths XX X X X XX IR R G B UV
Identification of the optical wavelengths used for
each measurement are displayed.
Spot2 Active False Current state of sample spot sense2.
Session Id Whole number 54
Identification number assigned to each sampling
and measurement session. This value is
incremented each time a new sampling and
measurement session is started (changes from
STOPPED to SAMPLING mode).
(Next) Datum Id Whole number 351055 ID of the next data line.
Datum Offset Whole number 351055 ID of the first data line stored on the instrument.
