B.2 Example Program for CR10(X) Dataloggers
Below is a portion of a CR10X program that measures the CS451/CS456.
The instructions below do not store data in final storage.
Instruction 92, Instruction 77, and processing instructions such as
Instruction 70 are required to store the data permanently.

After Instruction 105 is executed, the input location called “Data_1” will hold
the measured pressure, reported in PSI, and the input location called Data_2
will hold the measured temperature, in degrees Celsius. The results can be
further processed by the datalogger. Note that Port 1 specifies that the SDI-12
data line is to be connected to the Port C1.
