Accuracy Check And Calibration - Stanley 4V1H Multi Manual De Instrucciones

Manual Mode (Figure Ⓓ)
• Disables self‑leveling function and allows laser unit
to project a rigid laser beam in any orientation.
Accuracy Check and
Calibration
• 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.

• 0.4 mm/m x (10 m - (2 x 0.5 m) = 3.6 mm
(maximum offset distance)
• (-0.5 mm) - (1.0 mm) = -1.5 mm
• -1.5 mm ≤ ± 3.6 mm
(TRUE, tool is within calibration)

Place laser tool as shown with laser ON. Aim vertical
beam towards the first corner or a set reference
point. Measure out half of the distance D
