Vertex III
Functions and Construction
Congratulations to your choice of height measurer! The Vertex III is the
markets most modern instruments, carefully tested and approved to be
your reliable companion for years to come.
The Vertex III is primarily designed to measure the height of standing
objects, and most often trees. The instrument can also be used to
measure distance, horizontal distance, angle and inclination. The Vertex
instrument has with its ultrasonic measuring technique proved to be
especially useful in dense terrains with thick undergrowth, where
conventional methods such as measuring tapes, laser instruments and
mechanical height measurers are difficult to use.
To define a reference point in a secure and reliable way, the Vertex III
works with the transponder T3. The Vertex III communicates with the
transponder. This communication eliminates in an efficient way any mix-
ups of signals from other instruments or places (echoes). A measuring
operation will not in any significant way be disturbed by objects in
between the Vertex III and the Transponder T3. The reference point, i.e.
the T3, is used as a sight mark for height measuring and can be placed
at optional height, where visibility is the best in for example thick
vegetation. The reference point height is set in a special menu in the
Vertex instrument and automatically added to the measured height.
The Vertex III uses ultrasound to measure distances. Unlike for example
measuring tapes and laser instruments, ultrasound can be used also
when there is no free aim to the reference point. The ultrasound will not
pass through an obstacle, but looks for the shortest way around it.
Heights are calculated trigonometrically using the variables contained
when measuring angle and distance. The Vertex III automatically
assumes that the measuring object is perpendicularly positioned to the
ground.
With the Vertex III, an unlimited number of heights per object can be
measured. The instrument display can show the 4 lastly measured
heights per object at a time.
When using a relaskopic method to measure, an in-built BAF function
(Basal Area Factor) can be used for the Vertex III instrument to control
the minimum diameter for trees. The function is useful when some trees
in an area are covered by other, making the decision whether to include
the tree or to exclude it from the area difficult. By simply measuring the
distance between the tree and the plot centre, the Vertex III can calculate
the minimum diameter the tree should have in order to be included into
the counting.
Data can be sent through IR or and results can be stored and processed
in for example the Digitech Professional caliper, other PC or handheld
computer.

Description
Keys
The Vertex III has three keys: Two arrow keys and one ON key.
Function of the Arrow Keys
Use the arrow keys primarily to scroll through the menu and to change the
settings in the SETUP menu. By pressing down both arrow keys at the same
time, the Vertex III is turned off. Automatic turnoff time is set to approximately
25 sec.
When the Vertex III is turned off, the DME position can be activated with left
arrow key. The Vertex III turns into a distance measurer.
Right arrow key (IR) is used to transmit data through IR (Infrared light). Data
can only be sent after having made a measuring.
The ON Key Function
The ON key is used to start the Vertex III, to confirm a value and as a trigger
when measuring heights and angles.

Red Cross Aim
The red dot cross hair sight simplifies spotting the target and holding the
instrument straight when measuring heights, for best possible accuracy.
For best possible visibility, the light can be adjusted with the left arrow key
when aiming.
Loud Speakers
The Vertex III is equipped with a built-in signal that will beep when an angle
or a height has been registered.
Battery
The Vertex III uses an alkaline or a rechargeable battery of 1,5 V AA. The
battery is placed under the battery cap, plus pole + down.
The remaining battery tension is featured as an icon in the display of the
Vertex III.
A battery will in normal cases last for weeks or even months.

Important Facts on your Vertex III Instrument
The Vertex III uses ultra sonic signals to determine distances. Humidity,
air pressure, surrounding noise and, above all, the temperature can
affect the range and extension of the ultra sonic signals. The Vertex III
has a built-in temperature sensor that automatically compensates for the
divergence caused by variations in temperature.
In some cases, distances of 50 meters/yds and greater can be measured
without problems, and in other cases, the maximum distance can be
shorter than 30 meters/yds.
To increase and optimize the measuring accuracy, the instrument should
be calibrated on a regular basis. When calibrating, it is of utmost
importance that the instrument has been given enough time to stabilize at
ambient temperature.
If, for example, the instrument is carried in an inner pocket, it can take up
to 10 minutes before it has adjusted to current outdoor temperature. The
measurement inaccuracy pending on temperature is app. 2 cm/C.
An example: Your inner pocket holds +15 C/59F. Outdoor air
temperature is -5 C/23F. The measurement result will show 10,40 m/34
ft and not the correct 10,00 m/32.8 ft.
The measuring fault can be made permanent if the instrument is
calibrated before reaching the correct current temperature.
-Check your instrument daily and recalibrate if necessary
-Do not touch the temperature sensor at the front of the instrument (the
metal knob between the sight and the loudspeaker)
-Never calibrate the instrument before it has reached ambient temperature
When measuring heights, it is important to hold the instrument as straight as possible.
Correct Wrong
The trigonometric functions calculate the height based on two (2) angles
and one (1) distance. The distance can be measured manually with a
tape, or automatically by using the T3 transponder. If using a tape, the
distance has to be input in the Vertex before starting (angle-) and height
measuring.
