Appendix C. Example programs
These programs were written for a GRANITE 9 data logger. With slight modifications, they can be
used with other Campbell Scientific data loggers.
C.1 Configuring GRANITE Measurement
Module with CPIAddModule()
The following program sets CPI addresses and device names on VOLT 108s with serial numbers
1234, 1235, and 1236 and makes a single-ended measurement on each module SE 1 channel.
With slight modifications, this program can be used with other Campbell Scientific data loggers.
