How It Works
Using a patented TriSensor Technology
™
, the Di-
mension Master Plus sends out an inaudible, nar-
row ultrasonic beam of sound that bounces off the
“target” surface and returns to the unit as an echo.
The Dimension Master Plus then determines how
long the echo took to return and calculates a linear
distance reading, while internally compensating for
variables such as temperature. Unlike other ultra-
sonic measuring devices, the beam stays extremely
narrow as it travels from the Dimension Master
Plus. This exceptionally narrow beam allows you
to measure through doorways, down corridors and
in crowded rooms or offices for room-to-room
measurements.
To aid in accurate measuring, the Aim Assist
™
pointer lamp enables you to pinpoint the center of
the ultrasonic beam, thus avoiding interference
from obstacles or clutter in your path.
