will update itself with the most current real-time data every 60 seconds. The amount of time left until
the next update will be displayed in the bottom left-hand corner of the screen. When it does update, the
software will connect to the SDS, download the data, and re-draw the screen. Any screen settings, such
as the size of the graph and how zoomed in the user is, will not be changed. Note: if the Multiple SDS
Mode menu option is checked, then the SDS software will display a device selection box that will allow
the user to choose which device to gather the real-time data from (figure 2.37). If the Multiple SDS
Mode menu option is not checked, then the SDS software will gather real-time data from the first SDS

instrument at a time. To view multiple real-time data, click on the View Real-time data menu option
again and select the next SDS instrument.
