Timebase; Wavelengths (Microaeth Manager Only); Auto Restart Sampling (Microaeth Manager Only); Gps (Microaeth Manager Only) - Aethlabs microAeth MA200 Operating Manual

5.6.3. Timebase

The timebase setting permits the user to select a measurement integrating time of 1, 5, 10, 30, 60, or 300
second(s).
It is recommended to use a 30 or 60 second timebase for most 'human exposure' or 'ambient monitoring'
measurements. Faster timebases will result in higher noise, and are most useful either for direct source
monitoring (tailpipe analysis) or for other applications requiring extremely rapid data. A 300 second
timebase can be selected for longer run times and extended battery life. Please read section 5.2
Recommendations for Best Use Practices for more information.

5.6.4. Wavelengths (microAeth Manager only)

The wavelengths setting permits the user to select the measurement wavelength(s) used for particle
measurements.
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)

5.6.5. Auto restart sampling (microAeth Manager only)

The auto restart sampling setting permits the user to select if the microAeth will automatically start sampling
and measurements 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.

5.6.6. GPS (microAeth Manager only)

The GPS setting permits the user to select if GPS location recording is turned on or off.

5.6.7. Serial data streaming (microAeth Manager only)

The serial data streaming setting permits users to select if data streaming through the serial port is on or off.

5.6.7.1. Serial data streaming output format (microAeth Manager only)

The serial data streaming output format setting permits the user to select the streaming serial data output
format desired. Two format options are offered: Verbose and Minimal
For more information about serial data streaming output formating structures, see section 6.2. Serial Data
Streaming Structure.

5.6.8. Tape advance ATN threshold

The tape advance ATN threshold setting permits the user to enter the attenuation (ATN) threshold integer
value of 1 to 100 that 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.

5.7. Using the microAeth Manager Software

5.7.1. microAeth Manager Software Installation

The microAeth Manager for macOS
at https://aethlabs.com/microaeth/software. Before instrallation, check with the computer's system
administrator to make sure that the correct permissions have been granted on the computer to install and
run a new application. Please visit the AethLabs website for more information and to sign up for software
announcements and to receive notifications of software and firmware updates.
5.7.1.1. Installation on macOS
Download the microAeth Manager software to the computer running macOS
'microAeth_Manager_x.xx.dmg' on the computer. The virtual disk image will be mounted and a window
will open showing the 'microAeth Manager' application file. Drag the 'microAeth Manager' application
file to the 'Applications' folder of the computer. The application is now installed and ready for use with
the microAeth MA series instruments. When the microAeth Manager is first opened after installation on
the computer, a prompt may appear with the following message and verification request, '"microAeth
Manager" is an application downloaded from the Internet. Are you sure you want to open it?' Please
confirm to start using the application.
5.7.1.2. Installation on Windows
Download the microAeth Manager software to the computer running Windows
'microAeth_Manager_x.xx.exe' on the computer. A prompt may appear with the following message and
verification request, 'Do you want to allow this app from an unkown publisher to make changes to your
device?' Please confirm to start the installation wizard. The microAeth Manager installation wizard will
guide the user through the process of choosing the application installation location, creating a desktop
shortcut icon, and opening the Device Driver Installation Wizard for installing USB drivers required for
the computer to communicate with the microAeth MA series instruments. A prompt may appear with a
message and verification request to install the USB device software or drivers required. Please confirm
and complete both installation wizards. The application is now installed and ready for use with the
microAeth MA series instruments.
