How to Use the
Dimension Master Plus
Taking Accurate Measurements
Be sure to hold the Dimension Master Plus still and
directly parallel to the target area while taking a
measurement. The Dimension Master Plus may
give an inaccurate reading or a none/error message
if it is moved or held at an angle while you are at-
tempting to take a measurement.
Make sure that you hold the Dimension Master
Plus in such a way that your fingers do not cover
the three Ultrasonic Sensors on the front of the unit
or the Thermistor (automatic temperature sensor)
located on the bottom left hand side of the unit. The
Dimension Master Plus must be able to accurately
sense the ambient temperature of the surrounding
environment in order to work properly.
The Dimension Master Plus works best when
aimed at smooth surfaces that easily reflect the ul-
trasonic measuring beam back to the unit. For ex-
ample, when aiming the Dimension Master Plus at
a window covered by a curtain, open the curtain to
ensure an accurate measurement.
Taking a Linear Measurement
1. Place the back of the Dimension Master Plus
on a flat surface parallel to the target area
(e.g., hold the back of the unit against the
wall across from the parallel wall you are
targeting).
