8. Tips from the Pros
Take more than one measurement in situations where accuracy
is critical.
Take 3-4 measurements from the same position to compare the
consistency of each reading.
To accurately measure objects lacking
an inside corner from the rear of the
instrument, use a scrap piece of
drywall or other flat material to extend
the corner. Butt the Laser Distance
Meter up to the material (as shown).
If error message “ERR 2” appears,
place a white sheet of paper or reflec-
tive tape over the targeted measuring
surface to improve the return signal.
Be aware that when outdoors, the
working range of the tool decreases
significantly due to ambient light.
To make the laser beam more visible, aim it down in front of you
and then follow it with your eyes as you move it towards the
desired target.
