L-Series and FCS-18 Graphical User Interface User Manual

8. Measurements

This chapter discusses the various measurements that are available from

the L-Series. Measurements can be displayed on screen and stored to disk.
The ability to use the LSGUI program as a DDE server is also discussed.
Examples are provided for using collected data in spreadsheet programs
such as Excel.
