5.3 Example Programs
5.3.1 CR3000 Example Program without Wind Speed Correction
Shown below is an example program written for the CR3000 datalogger. The
datalogger measures the output from the sensor every 5 seconds and outputs
the average net radiation every hour. The calibration factor used will only
apply for one specific sensor. A new value will need to be calculated for every
different sensor based on the certificate of calibration for that sensor (see
Section 5.2).
