ArborSonic 3D Bluetooth Caliper


The Bluetooth Caliper is a tool that is able to quickly measure distance in millimetres between two points and transfer the value to PC over Bluetooth. This speeds up registering the irregular shape of the tree trunk and the position of sensors for ArborSonic 3D

  2. Calibrate the caliper (see the user's manual for more details).
  3. Start the ArborSonic 3D software and go to the Geometry page. To use the caliper, select Irregular shape.
  4. Turn on the caliper and click the Start Bt Caliper button.
  5. Measure the distances between the sensor pairs by following the instructions played through the speakers of the PC. Once all the points are registered, the shape of the trunk is shown on the screen
