Measuring Reference
Range
Range is specified between a minimum 2-inches to a maximum of
100-feet with an accuracy of 1/16".

Target Surfaces
Measuring errors may occur when aiming at surfaces composed
of colorless liquids (e.g. water), glass, Styrofoam or similar semi-
permeable surfaces. Aiming at high gloss surfaces may deflect the
laser beam and lead to measurement errors.

Hazards of Use
Be aware that errors in distance measurements may occur if the
instrument is defective or has been dropped, been misused or
modified.

Note
Conduct periodic test measurements to ensure the instrument is
measuring accurately and consistently. This is most important if the
instrument has been exposed to abnormal use. Always confirm
accuracy before and during important measurements. Keep the laser
distance measure optic clean and inspect for damage.
