L-703S Angular Adjustments The L-703S comes with pitch (vertical) and yaw (horizontal) angular adjustments to adjust (tilt) the laser to align it to reference points or a rotation axis.
  • Page 8 L-703S Level Vials When using the L-703S in machine tools, we typically will do measurements with the laser at the NORMal position (12:00) and then rotated with the spindle 180 degrees to the INverted position (6:00). There are level vials on the side of the laser to help you know if the laser is directly at 12:00 or 6:00.

  • Page 51: L-703Sp - How It Works

    One of the annoying parts of using electronic levels when re-surfacing a surface plate is you have to shoot the entire plate for flatness to see how the lapping process is going. This is a waste of time! With the L-703SP Surface Plate Calibration Systems, you can do quick-checks of a single line segment in about 5 minutes to see how much the flatness error has been reduced.

Due the extremely high resolution, it’s expected that the value won’t be exactly zero due to some measurement noise but they will be close.
