Vertex IV and Transponder T3 manual v.1.0 eng

SETTINGS

SETUP

All settings to measure heights, distances and angles and BAF Factors are made in the SETUP

menu. Choose between metric or feet, degrees or percentage, pivot offset, transponder

height and manual distance.

Start the Vertex IV by pressing ON. Press any of the arrow keys and ON to go to settings. Step

to the parameter using ON and change values with the arrow keys.

METRIC/FEET

Choose if height and distance values should be featured in METRIC or FEET. Shift with the

arrow keys and confirm your choice with ON.

DEG/GRAD/%

Select Angle unit as Deg (degrees 0.360), GRAD (gradients 0..400) or % (percentage) by

pressing the arrow keys. Confirm by pressing ON.

P.OFFSET (PIVOT OFFSET)

Change the value with the arrow keys and confirm

your choice with ON. The value is shown in

Metric/Feet.

The ”Pivot offset” is equal to the distance between

the front side of the instrument to the aimed point where the prolonging of the sight

line from the transponder and the top of the tree coincide.

The imagined point is located somewhere behind your neck and the value should in

normal cases be set to 0,3 m (1.0 feet).

Since the Vertex IV will presume that the transponder T3 is placed directly under the

aimed height of the measuring object (when the object is equal to a tree), a half of

the objects diameter should be added to the Pivot Offset. This compensates for the

diminishment of the tree top. When measuring tree heights, it is recommended to

add half the average diameter in the area, for improved accuracy.
