The maunfacturer suggests:
For calibration the best and less expensive approach is to use the
1.) build up the prototype
2.) wait for noon and note down the displayed (arbitrary) value
3.) ask your local Meteorologic Station for max. UV-Index of the day
4.) calibrate the unit accordingly
5.) go to 1.) the next day and re-calibrate, try to get different
conditions (cloudy & sunny)
That must be repeated until the error is acceptable.
