Chapter 6: Operation
• Data can be saved continuously by connecting the Lasair II particle counter to a
facility management system such as Facility Net and collecting your samples
while so connected. When using such a system, the data is saved continuously
on a computer, and the local data storage can be ignored. See Appendix B and C.
• Data can be saved from a mobile Lasair II particle counter by periodically
connecting to Facility Net to download the particle counter’s sample data. See
“Preparing for Remote Mode” on page 7-8. Also see Appendix C.
• Data can be downloaded in CSV format by means of the USB port. See
Appendix J.
