Item Brochure

The DP DME distance measurer is an
instrument accessory for the Digitech
Professional and the DP II. With the DP DME,
measurements to determine if a tree is within
the plot radius are performed with the help of
ultrasound technique.
The DP DME uses ultrasound to measure distances. The
ultrasonic method is well proven and used in instruments
such as the Vertex IV, the Vertex Laser and the DME. To
measure with the DP DME, the T3 transponder is placed in
the plot centre on a monopod staff. The DP DME is installed
on the caliper comport and works with the host computer
caliper and corresponding software. When measuring the tree
diameter with the caliper, the DP DME can be activated to
measure the distance from the tree centre to the transponder,
placed on the monopod staff in the plot centre.
The DP DME accessory will work with most Haglöf Sweden
computer caliper software applications after upgrading.
The software can be customized to, for example, refrain
from registering trees outside pre-set plot limits. The host
computer supplies battery and display for the DP DME, and
all instrument functions are software run.

The DP DME offers possibilities to have a distance connected with each
individual tree. When performing circular sample plot inventory, the distance
to the plot centre from the centre of the tree is automatically calculated by the
caliper software. The software can be programmed with functions to warn or
refrain from registering trees beyond the preset plot border.
Position the T3 transponder in the plot centre on the monopod staff. The
monopod, used for the DP DME, the Vertex IV, the Vertex Laser and the
DME, is customized for use in tough eld conditions. Measure the tree
diameter with the caliper and activate the DP DME in your computer
terminal. The software will determine the distance from the tree centre to
the plot centre.
