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.
;{CR10X}
;Program measures one 109 temperature probe once a second
;and stores the average temperature every 60 minutes.
