  • Page 18: Checking Accuracy

    This service manual discusses calibration specific to the 40-6640. All accuracy checking and calibration adjustments described below must be made while laser instrument is secured on a leveled platform.

  • Page 19: Calibration Adjustments

    If the laser lines are within the range created by the lines drawn 0.5 mm out from the reference lines, the laser instrument is operating within the accuracy specification of the instrument. [Accuracy specification is the same for the 40-6640 Self-leveling Laser: +1/8”/35 ft. (+ 3mm / 10m).] If accuracy does not fall within specification, continue to review the following sections and make the needed calibration adjustments.
