Squaring
1. Position laser square in the corner of the two surfaces to be squared (as
illustrated).
2. Turn laser square on.
3. Measure distance A at a point relatively close to laser square and make a
note of the distance.
4. Measure distance B at a point further away from laser square and make a
note of the distance.
Note: The greater the distance between the two points of measurement,
the greater the accuracy.
5. Compare distance A with distance B.
6. If distance A equals distance B, proceed to the next step. If distance
A does not equal distance B, then adjust the position of laser square until
distance A does equal distance B and proceed to the next step.
7. Measure distance Y at a point relatively close to laser square and make a
note of the distance.
8. Measure distance Z at a point further away from laser square and make a
note of the distance.
Note: The greater the distance between the two points of measurement,
the greater the accuracy.
9. Compare distance Y with distance Z.
10. If distance Y equals distance Z, then the two surfaces are square. If
distance Y does not equal distance Z, then adjust the position of the
surface which these distances relate to until distance Y does equal
distance Z.
Note: The plumb beams can also be used in operations such as
squaring window frames.
