General descripition
The Vertex clinometer is a device to measure distances based on ultrasonic sound and angles. It enables to directly measure tree height based on the trigonometric principle. For the measurement of distances a transponder is needed that is fixed at the tree and is an active component that submits a signal back to the Vertex. To determine the horizontal distance to the tree the transponder has to be fixed at a certain height (default 1,3 meter) that is defined in the settings menu.
The vertex clinometer allows to measure heights from variable distances to the target. The measurement results can be stored at the display to note them later down.
Handling
- Distance measurement
- Switch the transponder 'on' (when it is 'on', a quietly pulsative peep is hearable)
- Place the transporter at the target (Figure 2)
- Locate the place to measure it's distance
- Sight through the instrument pressing
When distances in a centre plot have to be measured, the 360° adapter can be placed at the centre point and the distances can directly be measured.
