I would, but I no longer have access to a second plate... Thanks!
My results: Using my i1Pro, mounted directly to the screen (C6 currently attached to my TriPod) and painter's tape to mark where the Meter and holder strap are, to try and get the Meter back to the same spot after each Dark Reading.
#1 - Is there a difference in readings between Activations on two different Plates. Yes
#2 - Activation on same plate two times in a row - different readings, but a lot closer than the Different Activations!
#1 - Meter on Screen calibrations are definitely not the way to go. Tripod gives a lot better over all average.
#2 - No matter how careful you are about returning the Meter to where you did the last reading after doing a Dark Reading, the results won't be the same. Forget the Dark Readings except between Work Flows.
#3 - If you're like me, and have 2 Meters, make sure the Plate and Meter Match re Serial #s. (And guess what, my Meter I've been doing all my calibrations with for the past while, was on the Wrong Plate!)
#4 - If possible, use a C6 to Profile to. This way time is not of the essence, re Dark Readings. If Dual Meter combos is too expensive - look into Renting the i1Pro to get your Profile, or, if you're lucky, someone else in your near vicinity and has the i1Pro or 2, will allow you to borrow his, or come over with it to make the profile.
#5 - Due to continuing changes in atmosphere, electrical values, etc - I always do a New Profile before each calibration session. It only tales a minute.
#6 - After calibration, before deciding on how your results look, turn the TV Off, wait a few seconds, then turn back on. Does sort of a reset to the New Values.
