Is
your Level Accurate?
by Lawrence
Winterburn
“Try
this test at your local tool store--you will be horrified to find that
more than half the brand new levels on the shelf are not accurate”
As in the illustration, place it on
a relatively
level surface. Make a light mark so that you’ll be able to locate the
exact
position. Align the level with the edge of the table or whatever you’re
using.
·
Visually inspect your level for
straight. Look down the edge.
·
Look at your level indicator,
memorize it’s position between the marks.
·
Roll the level 180 degrees, and
make sure you’re in the exact location
of the first reading. Is the reading the same?
·
Now flip the level end to end and
compare the reading.
·
Roll the level 180 degrees again
and compare.
You’ve now checked for level, now
check vertical
function on a doorway. Follow the same steps.
You’ll probably be quite surprised
to learn the
level you’ve used for years isn’t accurate. I’ve actually gone through
entire
assortments of levels in search of an accurate one. You’ll also be
surprised to
learn that just because a level sells for $80.00 doesn’t necessarily
guarantee
accuracy. Many are damaged during shipping and many aren’t actually
accurate to
begin with.
If your likely to
be hard on your equipment, as we are, invest in a plastic case to
protect your
investment when not in use.

wondered what the liquid is in a level?"
