CALIBRATION
-Calibrate? No. The sensor is set to the stored calibration before shipping.
-It is quite difficult to calibrate a UV sensor to read in absolute units, since you must have a source of known UV intensity and spectral distribution. More often you will simply want to calibrate the sensor in terms of a relative intensity. Refer to the detailed instructions for calibration on page 3 of the sensor booklet.
