  Do you have the user manual? If not, download it from http://www.sekonic.com/.

Basic operation is you set the meter for the ISO and shutter speed you're using, trip the flash then read the appropriate aperture to set on the lens from the meter. I don't understand what is the "tenth reading" you mentioned.

Michael H. Cothran   Since the L-308 reads in 1/10th stop increments, I'm going to go out on a limb and assume that this is what you are referring to.
Since cameras are not fine-tuned enough to adjust in 1/10th stop increments, you often need to round off your Sekonic's reading. For instance, if your reading is f8 plus 5/10's, the 5/10's would indicate 1/2 stop. If your camera is modern, this would be displayed as f9.5 I believe. If you have an older camera with an actual aperture ring, you would set the aperture halfway between f8 and f11.
Now, if your reading were 4/10's or 6/10's, or even 3/10's or 7/10's, you would probably still round it off to the setting I stated above. If the reading were 1/10 or 2/10, I would keep the reading @ f8. If it were 8/10 or 9/10, I would shoot @ f11.
FYI - Your eyes cannot normally detect exposure adjustments smaller than 1/3rd of a stop, which would be the equivalent of 3/10's stop on your Sekonic.
