Accuracy Check And Calibration - Stanley SPL3 Manual Del Usuario

unit to project the front laser beam to a new location.
• The laser point at the new location will be level with the
first point.
• Position the desired object until aligned with the laser
point.
Accuracy Check and
Calibration
NOTE:
• The laser tools are sealed and calibrated at the factory to
the accuracies specified.
• It is recommended to perform a calibration check prior to
its first use and then periodically during future use.
• The laser tool should be checked regularly to ensure its
accuracies, especially for precise layouts.
• When performing the accuracy checks, use the largest
area / distance possible, closest to the operating distance.
The greater the area / distance, the easier to measure the
accuracy of the laser.
• The lock must be in the unlocked position to allow
the laser tool to self-level before checking the
accuracy.
