So no other light is interfering.

The geometry of the devices is such that any light leakage is negligible --
well within the noise floor. If you want to go crazy with additional blackout
materials it shouldn't harm the measurements, but it definitely makes the
process less convenient.

Use the instrument as directed. Make sure it's laying flat and square against
whatever you're measuring, don't do anything silly like shine laser pointers
along the bottom of the device, and don't worry about the rest.

(And, of course, if you're really obsessed, you can determine for yourself
whether or not it's worth it by making two sets of measurements, one normally
and the other with whatever improvements you have in mind; if you like the
improved version better, then that's your answer.)
