Your laser measuring tool is a precision instrument.. Please observe the following
guidelines to ensure optimal performance
o Do not direct the laser-measuring tool towards the sun or other sources of
bright light This may cause an Error reading or inaccurate measurements.
o Do not use the laser measuring tool as a leveling tool..
o Do not operate the laser measuring tool in wet, dusty, sandy, or other
adverse environments. Such conditions may damage inner components and
affect measuring accuracy
o When the laser measuring tool is brought into a warm environment from
very cold conditions, or vice versa, allow it to come to the surrounding
temperature before use_
o Measuring errors can occur when measuring toward colorless liquids (e,g,.,
water), clean glass, Styrofoam, or similar translucent or low-density materials,
o High-gloss surfaces will deflect the laser beam and result in Error measurements.
a Very bright surroundings combined with a very low reflecting surface will
reduce the measuring range and accuracy
o Do not immerse the tool in water, Wipe off dirt with a damp, soft cloth, Do
not use aggressive cleaning agents or solutions Treat the optical surfaces
with the same care that you would apply to eyeglasses or cameras
o The accuracy of the tool must be checked before use after it has been
dropped or subjected to other mechanical stresses.
