I have the earlier model and found that if I put a white dot on the 
outside of the read orifice on the side I'm looking at while reading, 
it made it much easier to see what I was doing.

Also for linearization, I use this 21-step test strip:

The markings at the corners of the test patches, particularly with 
the dot on the read orifice, help me center the spetro.

I use the Calibration mode prints only for ink limits and relative 
density.  It's usually obvious when making these readings if you've 
hit some white paper.  You can always make a couple reads to make 
sure.

Hope this helps.
