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.

2: 0 Start Measurement (aM0!)
3: 1 Port ;this is where the white wire is connected

End Program
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.
