Step 2 - Straight Measure

When measuring the straight, switch the laser off again. Probe the inside of the cylinder as shown here.

  • Measure along the first end of the cylinder shown in red points. Measure 3 points minimum. Do not take in a continuous stream of points, as the location of each point is much more critical.


  • Press the red button, then measure along the second part of the short straight as shown with the green cylinder.


  • Press the red button when finished with the second part of the straight.
