Scanner The Two-Axis Scanner option allows the user to monitor and track aerosols and plumes across an area. This section will walk through controlling the scanner and saving custom scan patterns for repeated measurements. 11

7.1.1. Configuring the mpl.ini file NOTE: This step is already completed on all new purchases. To enable the scanner options in SigmaMPL: Open the mpl.ini file located in the main SigmaMPL folder (C:\Program Files (x86)\sigmampl) and change the following lines as shown below. Section Parameter Value [MAIN] SCANNER 1 [SCANNER] CONTROL 1 These changes will enable the scanner display in SigmaMPL and allow the software to control the scanner. 7.1.2. Hardware Tab Options Upon opening SigmaMPL s Real Time Hardware Control option, the Scanner section will be displayed in the Hardware Tab. This is the section where the user can control the scanner. Figure 10: SigmaMPL Hardware Tab for Scanner Control The following Scanner options are available: Control Scanner Check to enable scanner control. COM Port Select the proper COM port to move the scanner. Always select the lowest COM port. Pattern File Click to load a custom scan pattern. This will override the Manual Control settings. Refer to Section 7.1.3 for details on how to create a scan pattern. Manual Control Input the desired Azimuth and Elevation angle settings. Click Move Scanner to have the scanner move to the desired position. NOTE: The scanner will not move if SigmaMPL software is collecting data. Every time SigmaMPL software is opened, the scanner will go through an initialization sequence to determine its position. This 12

initialization sequence takes approximately 1 minute and 45 seconds to complete. If a scan pattern file is loaded, then the pattern will override the Azimuth and Elevation settings. The status of the scanner is displayed in the Hardware Status section on the left side of SigmaMPL. Enable Compass Heading Enter the pointing of the scanner in relationship to true North. This offset will be added to the scanner coordinates in the Local Tab and the Map Tab. 7.1.3. Creating Custom Scan Patterns The Scanner Tab is where the user can create custom scan patterns. A scan pattern is a file that stores a series of moves to let the scanner operate without the user being present. There are two ways to create a scan pattern: Basic and Advanced. Basic The basic scan pattern option allows the user to create a scan pattern by selecting the Start Angle, End Angle and Increment for both the Azimuth and Elevation axes. Figure 11: Basic Scan Pattern Setup 13

The selected sweep of the scanner is displayed in Green on the left side. The Red arrows show the number of steps (based on the desired increment) that the scanner will take to move from the Start Angle to the End Angle. Click the rotation arrow to select the desired rotation direction of the scanner (Clockwise or Counterclockwise). Once the desired angles are set, select the Primary axis (azimuth or elevation). The Primary axis will complete its sweep before the secondary axis moves. For example, In Figure 11 above, the scanner will move in the azimuth direction (Primary axis) from -20 to 50 in increments of 5 with the scanner at 0 elevation. Once the scanner hits 50 azimuth, it will move back to -20 and move in the elevation direction from 0 to 5 then sweep azimuth from -20 to 50. After deciding on a scan pattern, click Set Scenario to load the pattern immediately or Save to File to save the pattern for future use. If a pattern is already created, click Load from File to open it. Figure 12: Hardware Status Message Denoting Updated Scan Pattern Advanced The advanced option allows the user to input Azimuth and Elevation coordinates in any order to move the scanner in a non-sequential way. Figure 13: Advanced Scan Pattern Setup Menu 14

Click Insert to add a new line, Delete to remove a line, and the Up and Down buttons to re-order the coordinates. The options to Set Scenario, Save to File, and Load from File from the Basic option menu are still available. Once a Scan pattern is Set or Loaded, the Hardware Status will update with Scan Pattern Updated. When the Move Scanner button is clicked, the scanner will move according to the selected Scan Pattern. 7.2. Weather Station The Weather Station option incorporates real time weather data with the MiniMPL data. The Weather Station provides Temperature, Humidity, Barometric Pressure, Wind Speed, Wind Direction and Dew Point data. 7.2.1. Configuring the mpl.ini file NOTE: This step is already completed on all new purchases. To enable the Weather Station data in SigmaMPL: Open the mpl.ini file located in the main SigmaMPL folder (C:\Program Files (x86)\sigmampl) and change the following line as shown below. Use the device ID found on the front of the Sensor Suite Control Box.
