B.1 Example Program for Measuring a CMP6
Although this example is for the CR1000X, other CRBasic data loggers are
programmed similarly. The following program measures the CMP6 every
second and converts the millivolt output to W•m
–2
. A sensor calibration of
14.33 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-1 .
