Appendix B. Example Programs

B.1 Example CRBasic Program

This example can be used directly with CR800 series, CR1000, CR3000, and

CR5000 dataloggers.

'Program measures one 107 temperature probe once a second and
'stores the average temperature every 60 minutes.

B.2 Example Edlog Program

This example can be used directly with CR10X dataloggers. With minor

adaptations, it can also be used with CR10, CR500, CR510, CR23X, and

CR7X dataloggers. More adaptation will be needed with the 21X and CR7

dataloggers. Contact a Campbell Scientific application engineer for help with

any datalogger program.
