Hi all

I am just testing and calibrating my solar/UV board. My question is does the UVM-30A sensor normally require much in the way of calibration? I ask because here it is a sunny day and I have the sensor uncovered outside and with the UV_Transmission = 100 the reading is very high. At UV_Transmission = 150 still without any cover I come close to the expected reading from our National Institute of Water and Air. Does this seem usual or could my sensor be of some dubious quality?

Many thanks
