9. The maximum vertical deviation (d) is:
dmax = 2X H (door opening) x ±1/8" ÷ 33'
Example: for a door opening height of 7', the
maximum permitted deviation (d) is:
dmax = 2 x 7' x ±1/8" ÷ 33' = ±0.05"
Therefore, the measurement between points III
and IV on the upper door opening should not
exceed 0.05" in a 7' doorway.
Plumb Dot Accuracy (3522-20)
A free measuring distance of approximately 33' be-
tween floor and ceiling on a firm surface is required
for this check. It is suggested to install riser block, if
not already equipped.
1. Place the tool within 1' of the floor.
Turn the tool to
Level & Plumb Lines Mode.
2. Set tool on ground and mark the center of the
plumb point on the ceiling (point I). Also, mark the
center of the plumb point on the floor (point II).
3. Rotate the tool 180°. Align the center point of the
laser beam directly onto the floor point II.
4. Mark the center of the top plumb point on the
reference line on the ceiling (point III).
5. The distance between points I and III on the ceiling
is the deviation (d) of the tool. This distance should
not exceed 1/8" (max.) at 33'.
For the Measuring distance of 2 x 16.5' = 33',
the maximum allowable deviation (d) is:
33' x ±1/8" ÷ 33' = ±1/8".
