5.7.3.3.2. Application time synchronization
The application time synchronization ‘Sync now’ button in the ‘Change time options’ window of the
microAeth Manager (click the ‘Time options’ button on the main application window), can be used
to manually synchronize the time of the microAeth and the computer. When time is synchronized, a
confirmation notification will be displayed below the button in this window.
5.7.3.3.3. Timezone offset
The timezone offset dropdown and ‘Set timezone offest’ button in the ‘Change time options’ window of
the microAeth Manager (click the ‘Time options’ button on the main application window), can be used
to select and set a timezone offset from Coordinated Universal Time (UTC) to be used as part of the ISO
8601 time and date format in the instrument and recorded with instrument measurement data. Daylight
savings time offsets are not automatically adjusted by the instrument or the microAeth Manager. Select
the desired value from the dropdown and click the button ‘Set timezone offset’ to save. When the
timezone offset is saved, a confirmation notification will be displayed below the button in this window.
5.7.3.4. Memory
The microAeth Manager displays the percentage of memory available in the microAeth. The microAeth
has 16GB of memory which can store 31,250,000 data lines.
1 second timebase: 361 days of data
5 second timebase: 4.95 years of data
10 second timebase: 9.90 years of data
30 second timebase: 29.72 years of data
60 second timebase: 59.45 years of data
300 second timebase: 297.27 years of data
AethLabs recommends regularly deleting data on the microAeth as all unsynchronized data is
downloaded together from the microAeth to the microAeth Manager local database on each different
computer.
5.7.3.5. Firmware
The microAeth Manager displays the operating system firmware version running on the microAeth.
5.7.3.6. Flow setpoint
The flow setpoint dropdown can be used to select a sampling flow setpoint of 50, 75, 100, 125 or 150
ml/min. Select the desired value from the dropdown and click the checkmark to save and the ‘x’ to
cancel.
A flow rate of 100, 125 or 150 ml/min is highly recommended when using DualSpot
®
loading
compensation.
The timebase dropdown can be used to select the measurement integrating time of 1, 5, 10, 30, 60, or
300 second(s). Select the desired value from the dropdown and click the checkmark to save and the ‘x’ to
cancel.
The wavelengths dropdown can be used to select the measurement wavelength(s) used for particle
measurements. Select the desired value from the dropdown and click the checkmark to save and the ‘x’
to cancel.
1 Wavelength: IR (880 nm)
2 Wavelengths: IR (880 nm), UV (375 nm)
5 Wavelengths: IR (880 nm), Red (625 nm), Green (528 nm), Blue (470 nm), UV (375 nm)
The sampling mode dropdown can be used to select if the instrument is in SingleSpot™ or DualSpot
®
loading compensation sampling mode. Select the desired value from the dropdown and click the
checkmark to save and the ‘x’ to cancel.
A flow rate of 100 or 150 ml/min is highly recommended
when using DualSpot
®
loading compensation. Although DualSpot mode can be used in many sampling
scenerios, for best results it should be used in stationary applications.
5.7.3.10. AutoSample
The AutoSample dropdown can be used to select the autosample mode. Select the desired value from
the dropdown and click the checkmark to save and the ‘x’ to cancel.
Off: Automatic start of sampling and measurements will not occur.
Resume after power loss (Resume): If the instrument was previously sampling and experienced a
power failure. If this setting is on, the instrument will automatically start sampling and measurements
when it turns on from a loss of power or some other event that caused the instrument to turn off.
External power control (Ext Power): If the 5V barrel jack of the instrument is supplied with power, the
instrument will automatically turn on and start sampling and measurements. If power is removed from the
5V barrel jack of the instrument, the instrument will automatically stop sampling and measurements and
turn off.
The GPS toggle switch can be used to turn GPS recording on or off.
The serial baud rate dropdown can be used to select the serial baud rate for all data transmitted through
the serial port. Select the desired value from the dropdown and click the checkmark to save and the ‘x’ to
cancel.
NOTE: When installing firmware using the instrument bootloader, the baud rate is always 1000000 even if
the baud rate setting has been changed.
