Page: 42 / 44

Q Is the laser safe?
A QML is rated class 2 per IEC 60825-1 and CDRH 21. This
rating is considered generally safe because the natural blink
reflex will limit exposures to no more than 0.25 seconds. It
is always recommended to not look directly into a laser
Q Do you need to use tripods?
A No. You can place the lasers directly on the floor . You
can also use other tripods. Visibility on the floor is likely
better if the lasers are placed on tripods.
Q How accurate is QML
A Typically, about 1/8” (3mm). There are regions of
greater and less accuracy. Be cautious of very shallow X
angles.
Q Is QML waterproof? Is it dustproof?
A QML is rated IP54, which is considered splash proof dust
resistant beyond what is normally present on a
construction site.
Q Can QML be used outdoor?
A QML is a visible laser system. Daylight normally limits
the ability to see the lasers to indoor areas. At night, QML
can be used effectively outdoors.
Q If the floor is sloped, does it affect accuracy?
A No. The laser “X” goes from floor to ceiling, though you
can see it only off of surfaces that reflect lasers.
