i1lt has been sitting in a draw for years. Still ok to use?
I have an Eye One LT that has been sitting in a dark draw since that last time I used it back in 2009. I assume at this point it won't be accurate since I know calibration drifts with time. Should I just throw it away or does it have any useful purpose at this point? Can it still measure lumens accurately or serve any other useful purpose?
I am planning on buying a new meter soon but I wanted to ask about the i1lt before I just junk it.
