Hi Matthew,

Make sure it's calibrated properly? Just go into the Tools menu;
do a Calibrate; and then use Measure to take some spot measurements on
a few things, maybe try the paper white from something you've measured
before and compare the Lab values.

When you calibrate the spectro, make sure you've got it sitting directly
in the calibration base, and that the nose of the spectro is flush with the
white cal tile. (And of course, this has to be on the round white tile in
the calibration base, not on the paper you're measuring).

Other than the spectro calibration, there's nothing else that can be off, as
long as the spectro is functioning properly and it's plugged into a powered
USB port. (It does need power to function properly, so grasping at a few
straws that are still possible: if you have it plugged into a powered hub,
make sure that your hub is actually still getting power, and that it's DC
power adapter didn't possibly get pulled out slightly). Also, double-check
the spectro cable. Unplug it from both ends, then re-insert it all the way
into the spectro and then plug it back in on the other side.

After going through all this, what kind of paper white meausurements are
you getting?
