Is it me, or is the quantum meter way touchy? I'm having a hard time getting repeatable results and getting the sensor level. When repeating measurements, I can get very general ballpark (a big ballpark) results, but no 2 measurements are the same.
It seems that even a 5 or 10 degree tilt on the meter can influence the reading significantly.
