Measurement Summary
The following section is a brief summary of how the laser is used to measure straightness, flatness,
squareness, levelness and parallelism. Note that if a machine is going to be aligned, rather than just
measured, it is important to put the laser on an instrument stand. If the laser is on the machine bed or
table, adjustments will likely move the laser and affect the setup.

Measuring Straightness, Flatness and Squareness
Measuring Straightness
To measure (horizontal) straightness of a surface or machine axis, two reference points and one vertical
laser plane are needed.
1. Mount a target horizontally at the closest reference point to the laser and adjust the target so
that it detects the laser.
2. Zero the target and move it to the farthest reference point from the laser. Use the YAW
adjustment to produce the same reading for both reference points.
The laser is now parallel or “bucked in” to the reference points.
3. Place the target at intervals along the surface or machine axis.
Any deviations from zero are a measure of straightness relative to the reference points. If the target is
mounted so that its top is to the left of the laser plane, then a "+" reading means the measured point is
to the "left" of the reference points and a "-" reading means the point is to the right of the reference
points.
