7.2.3.3 CR10(X) Example Program without Wind Speed Correction
Shown below is an example program written for the CR10(X) datalogger.
TABLE 7-5 provides the wiring for the example program. In this example, the
datalogger measures the output from the sensor every 60 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 (Section 7.2.2, Calibration Factor).
