Short Cut cannot edit programs after they are imported and edited
in
CRBasic Editor
.
If there is a need to import Short Cut code into the CRBasic Editor to create or
add to a custom program, follow the procedure in Appendix A ,
Importing Short
Cut Code Into CRBasic Editor
(p. A-1)
. Programming basics for CRBasic data
loggers are provided in the following section. A complete program example for
a select data logger can be found in Appendix B , Example Program
(p. B-1)
.
8.2.1 CRBasic Programming
In CRBasic, the AM25T() instruction is used to control the AM25T
multiplexer with the data logger. The instruction measures the PRT
incorporated in the AM25T and uses it as a reference temperature for
thermocouple measurements. The AM25T() instruction and parameters are as
follows:
AM25T (Dest, Reps, Range, AM25TChan, DiffChan, TCType, TRef,
ClkPort, ResPort, ExChan, RevDiff, SettlingTime, Integ/f
N1
, Mult,
Offset)
For information on this instruction, refer to the CRBasic Help.
9. Maintenance
Maintain a level of calibration appropriate to the application. Campbell
Scientific recommends factory recalibration of the AM25T every five years.
Consider the following factors when setting a calibration schedule:
• the importance of the measurements
•
how long the multiplexer will be used
• the operating environment
• how the multiplexer will be handled
