Appendix B. Example Programs
B.2 CR1000 Example Program for Measuring a
CMP11
Although this example is for the CR1000, other CRBasic dataloggers are
programmed similarly. The following program measures the CMP11 every
second and converts the millivolt output to W•m
–2
. A sensor calibration of
8.55 µV / W • m
–2
is used for the example program. Every 10 minutes, the
program outputs the average and standard deviation of the flux (W • m
–2
)
measurements.
Wiring for this example is given in TABLE B-2 .
