Set-Up and Operation
Range of Applications
Use the unit in single mode to measure distances of 0.6 - 18 meters indoors. If
no smooth surface is available of you want to measure a longer distance,
please use the dual mode and the target. With the target you can measure
distances from 1 to 75 meters.
In
Single-Mode
the unit throws ultrasonic waves against a smooth, solid
surface. These waves are reflected by the surface and detected by the unit.
The distance is calculated from the elapsed time.
In
Dual-Mode
the unit sends an infrared beam to the target, which in turn
sends out an ultrasonic sound wave. This ultrasonic sound wave is detected
by the unit and the distance is calculated. This procedure minimises
measurement errors on longer distances.
For convenient carrying a pouch is supplied with the unit. You can easily
attach it to your belt and have both hands free.
