Step 4. Run the Program Example
A diskette labeled SCXI Application Examples is included in the Getting Started with SCXI pack. This diskette
includes three example programs written to illustrate the use of the SCXI-1102 with thermocouples. The three
example programs are written using LabVIEW, LabWindows/CVI, and C programming language.
Each of the example programs perform the measurement of the J-type thermocouple and displays the
temperature reading in degrees Celsius. Below is a general flow chart of the example programs that shows the
fundamental steps in programming the SCXI-1102 for thermocouples.
