Humidity and Altitude
—
Humidity and altitude
can affect the maximum measurement distance and
beam angle of all ultrasonic distance-measuring
tools. As the humidity increases or the altitude de-
creases, the maximum measurement distance and
beam angle is reduced. As humidity decreases or
the altitude increases, the maximum range and
beam angle is increased.
Therefore on a day with a very low humidity you
are more likely to detect objects over a wider field
of view and at a greater distance.
Outdoor Measurements
—
The Dimension Mas-
ter Plus is primarily designed for indoor use. It may
also be used outdoors, provided there is only light
wind. A strong wind will tend to affect the maxi-
mum measurement range.
Moisture —
Your Dimension Master Plus is a
high precision measuring device that is open to the
atmosphere. For this reason, it should not be used
in conditions (i.e., rain, mist, etc.) where moisture
can get within the unit.
