THE DP DME
ULTRASOUND DISTANCE MEASURER ACCESSORY
The DP DME distance measurer is a unique instrument accessory for the DP II Computer Caliper and Digitech Professional. The DP DME works with ultrasound signals to determine distances, and is used to measure radius in sample plots and to quickly determine if a tree is standing within or outside the sample plot limits. A complete DP DME system consists from the DP DME measuring instrument accessory, a transponder T3, and a monopod staff with adapter
FROM THE CENTER OF THE TREE TO THE CENTER OF THE PLOT
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.
Computer caliper software
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.
