The spaces on the lens are half stops. I don't have a Digisix in front of me, but the marks on the meter are presumably 1/3 stops. If your meter reads a 1/3 increment, just use the closest 1/2 stop on the lens.
EDIT: As an example, you could view your lens as having settings for the following f-stops: ... 8 9.5 11...
Your meter then has increments of ... 8 9 10 11...
If your meter then reads f9 or f10, just use f9.5 on your camera (until you get a bit more experienced and confident to play around with the exposure according to the conditions)
