Example of Comparison report
A good comparison requires the two sensors to be mounted side by side, either horizontal or both the
same orientation and angle. No obstructions are allowed and a clear sky is required. For a useful
result it takes at least a few hours around noon, but better is to measure a full day. Keep in mind that
an outdoor calibration of a pyranometer according to the ISO 9847 standard requires a 2 to 3 days
period with clear sky, or longer for cloudy conditions. If a comparison is required where all individual
data points are required, a normal logging can be used. The deviation between the two sensors then
needs to be calculated afterwards from the downloaded csv file.
15 Device setting
This menu gives the option to set language (at present only English and Dutch are implemented) and
set the time and date. Device info gives the serial number, and hardware and firmware versions.
Finally the last Meteon calibration date is shown. Also the PC software has an option to transfer PC
time and date to the connected Meteon.
