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.

• If the sum is not less than or equal to the calculated
maximum offset distance the tool must be returned
to your Stanley Distributor for calibration.
Maximum Offset Distance:

• 0,8 mm m x (10 m - (2 x 0,5 m) = 7.2 mm

• (0,5 mm) - (- 1,0 mm) = 1,5 mm
• 1,5 mm ≤ 7.2 mm
