How you attach the glasses to the meter depends on the shape of your meter... you might need tape, but rubber bands might work in many cases.
The glasses are NOT tinted gray... most are slightly green and are a bit darker than clear. Each different brand/model of 3D glasses seem to have a different color to them. That means if you have 4 different pair of 3D glasses, you'll see 4 different renditions of the same image because each pair will alter gray and color differently. It's always best to use the same brand/model of 3D glasses for all viewers so everybody gets the same calibrated images. The glasses also have to be turned on and stay on for the entire 3D calibration session.
One problem you WILL have... because the 3D glasses are darker and because half the frames will be "blocked" from getting to the meter, darker shades of gray will get difficult to measure much sooner than when measuring 2D. In fact, if you can measure 10% with your meter in 2D, 30% is likely to be your lower limit for 3D calibration and if you can only get down to 20% reliably in 2D mode, you're going to be able to get to about 40% in 3D mode.
