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
To switch the instrument 'on', press the 'on-button'. The menue pages can be selected by pressing the 'DME' and the 'IR' buttons. To switch the instrument 'off', press 'DME' and 'IR' simultaneously for a while. Place the transponder directly in front of the Vertex and press 'DME' to switch the transponder 'on'.
1. 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 the 'DME-button' (Figure 3)
- The cross (Figure 4) will shutdown, when the measurement is done
- The horizontal distance appears at the display
2.Height measurement
- Place the transporter at the tree (Figure 2)
- Locate a place with a good view to the tree crown
- Determine the horizontal distance by measuring the tansponder (Figure 4)
- Measure tree bottom (Figure 5) and tree crown (Figure 6)
- Read the resulting height (Figure 7)

Figure 5: measurement tree bottom
Figure 6: tree crown measurement
Figure 7: Display results
3. Distances within a centre plot
- Place the transponder at the 360° adapter and locate both vertically at the centre point
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.
