Make sure that you wrap it in a
straight line so that the end of the tape
lines up with the vernier line of the tape.
Note the reel diameter, in this case, 4.534
inches.
INFO-The tighter and straighter the pi tape
is, the smaller and more precise the
reading will be.
Place the Reel Diameter Tape™
magnet on one of the blades at the right
end of the reel. Again, make sure that the
magnet does not touch the Reel Diameter
Tape™ when you wrap it around.
Keep tension on the Reel Diameter
Tape™ as you rotate the reel and wrap
the Reel Diameter Tape™ around the reel.
Make sure that you wrap it in a
straight line so that the end of the tape
lines up with the vernier line. Note the reel
diameter.
