User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ VERTEX IV Congratulations to your choice of height measurer! The Vertex IV is a market leading ultrasound technology instrument, carefully tested and approved to be your reliable companion for years to come. The Vertex IV is primarily designed to measure heights of standing objects, and most often trees. The instrument can also be used to measure distance, horizontal distance, angle and inclination. The Vertex IV its ultrasound measuring technique has proven 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 IV works with the transponder T3. The Vertex IV communicates with the transponder. This communication eliminates in an efficient way any mix‐ups of signals from other instruments or places (echoes). A measurement operation will not, in any significant way, be disturbed by objects in between the Vertex IV and the Transponder T3. The reference point, i.e. the T3, is used as a sight mark for height measurements and can be placed at optional height, where visibility is the best in for example thick vegetation. The reference point height is set in the Vertex instrument and automatically added to the measured height. The Vertex IV 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 look for the shortest way around it. Heights are calculated with the help of trigonometry, and the variables contained when measuring angle and distance. The Vertex IV will assume that the object to measure is perpendicularly positioned to the ground. With the Vertex IV, an unlimited number of heights per object can be measured. The instrument display can show the four last measured heights per object at a time. When working with a Factor Gauge method, a built in BAF function (Basal Area Factor) can be used for the Vertex IV instrument to control the minimum diameter for trees. The function is useful when some trees in an area are covered by others, making the decision on whether to include the tree or to exclude it from the area difficult. By simply measuring the distance between the tree and the measuring point, the Vertex IV can calculate the minimum diameter the tree should have in order to be included in the counting. Data can be sent through IR or Bluetooth and results can be stored and processed in for example the Digitech Professional/DP II computer caliper, other PC or handheld computer. 5 User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ HAGLÖF SWEDEN® Haglöf Sweden® AB is a family owned company with long time experience of developing and manufacturing professional inventory and cruising products.

With a number of unique features, the Vertex IV is one of the best field adapted instrument systems for use in tree height measurement applications. DESCRIPTION Display Lens Vertex aim IR transmitter Battery lid Temperature sensor Ultrasound transceiver DME button IR button ON button 7 User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ INFORMATION The Vertex IV system is based on ultrasound technology and advanced electronic angle measurement. The instrument is built in a compact, sealed and rugged instrument house. The ultrasound method is especially well adapted to measure distances in sample plots in dense forests. The Vertex IV uses ultrasound to measure the distance, and a high quality tilt sensor to measure angles. The ultrasound technique allows for high precision measurements on short distances. Ultrasound works in dense forests and where the visibility of the measuring objects is completely or partially obscured. The ultrasonic signals are emitted from the Vertex IV instrument to the transponder T3, and the distance in between these units is presented in the instrument display. Object heights are calculated with the measured variables from the distance and the angle. The T3 is used as transponder for the ultrasound and as a point of reference. The T3 transponder works both for 60° aimed, or directed measuring, for example when pinned to a tree stem, and in a 360° circle when installed on the adapter and monopod plot staff, especially designed for circular sample plot work. Together with the results for angle, the horizontal distance to the reference point are calculated with the Vertex IV. The Vertex IV has a built in function to determine if border trees are to be included or not when measuring with a factor gauge. To use, measure the diameter of the tree, and then the distance from the tree to the measuring point. The Vertex IV will display the results on if including or not the particular tree in the plot. Optional Basal Area Factors when metric is setup: 0,5, 1, 2, 3, 4, 5, 6, 7, 8, 9. Basal Area Factor (BAF) when feet is setup: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50. Vertex IV has built in IR and Bluetooth® to send the data to the Digitech Professional/DP II computer calipers, to other handheld computers or to your PC. 8 User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ QUICK GUIDE TURN ON/OFF T3 TRANSPONDER ON Hold the Vertex IV loudspeaker approx. 2 cm/1 in. from the T3 transponder.

The horizontal distance is displayed. Horizontal distance measurements are useful if a circular sample plot is located in a slope. DISTANCE MEASURING (DME) Activate the T3 transponder and place it on/by the object where the required distance to be measured. Press the DME button. The measured distance is displayed in meters or feet. Metric or feet is set in the SETUP menu. 10 User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ KEYPAD The keypad is easy to operate to step through the different menus. The Vertex IV instrument uses two arrow
buttons (DME and IR) and one ON button.
ON The ON button is used to start the Vertex IV, to confirm a value and as a trigger when measuring heights and
angles. ON is also used when choosing between menus and/or functions.
ARROW BUTTONS The two arrow buttons are marked ”DME” and ”IR” and used to navigate menus, change values and options. DME When the Vertex IV is OFF, distance measurement can be activated with a short press on the DME button. When measuring heights, the brightness of the Vertex sight‐cross can be changed with the DME‐button. IR Send data while measuring with IR or Bluetooth® with the IR‐button. OFF (DME + IR) Simultaneously press the DME and IR‐buttons to abort a function or turn the Vertex IV OFF. The Vertex IV automatically turns itself off after 60 sec’s of inactivity. THE VERTEX SIGHT The Vertex IV has a high intensive, red Vertex sight‐cross. The sight has no magnification which facilitates identification of nearby objects. The intensity of the Vertex sight‐cross light can be adjusted while measuring, and by pressing the DME‐button. There are 7 different intensity modes. 11 User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ SETUP – SETTINGS In the SETUP MENU, settings are made to measure heights, distances and angles. 1. Press ON to activate the instrument. 2. Choose SETUP and press ON to confirm this option. 3. Use DME and IR to change values and options. Press ON to confirm your choice and the next option will appear. The settings will be saved when all steps are made. Abort by pressing DME and IR simultaneously. METRIC/FEET: Choose if height and distance values are to be featured in METRIC or FEET. Shift with the arrow keys and confirm your choice with ON. DEG/GRAD/%: Choose angle unit in DEG (degrees 0…360), GRAD (grads 0…400) or % (percent) by pressing the arrow keys. Confirm by pressing ON. P.OFFSET: The Pivot Offset is equal to the distance between the front side of the Vertex IV 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 is normally set to 0,3 m (1.0 feet) Since the Vertex IV will presume that the transponder T3 is placed vertically under the aimed height of the measurement object (when the object is equal to a tree), a half of the object’s diameter should be added to the Pivot Offset. This compensates for the tapering of the tree. When measuring tree heights, it is recommended to add half the average diameter in the area, for improved accuracy. T.HEIGHT: The transponder height or other reference height shall conform with the distance from the ground to the reference point. The value is set in metric/feet. T.HEIGHT typically refers to the centre of the T3 transponder or zero (0) if the reference point is the ground or the lowest part of the object to measure. The Vertex IV adds the preset T.HEIGHT to the measured height. The normal value for breast height is 1,3 m (4,5 ft.). 12 User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ M.DIST: The M.DIST function is useful when measuring without transponder. Change value with the arrow keys and confirm with ON. The value is shown in metric/feet. M.DIST is the manual distance from the front of the Vertex IV to the reference point on the object where the first angle is measured. Make sure that the T.HEIGHT is correctly set, i.e. the height to the chosen reference point. 
NOTE! The accuracy of the manual distance affects the accuracy of the height result.
BAF: When working with Factor Gauge or Prism some trees cover others and this can cause problems. A frequent problem is to determine if to include or exclude border trees in the plot. With the Vertex IV built in BAF function, the minimum tree diameter for trees to be included can be featured. By measuring the distance from the tree to the measurement point with the Vertex IV, the instrument can calculate the minimum diameter for a tree to be included. These BAF factors are available in the Vertex IV: 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9 (m2/ha) or 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 (ft2/acre) The Vertex IV can compensate for the minimum diameter even if the terrain is inclined. CONTRAST – SETTING THE DISPLAY CONTRAST 1. Press ON to activate the instrument. 2. Choose CONTRAST and press ON to confirm this choice. 3. Use DME and IR to change the contrast of the display, 47 different modes are available. (Min 80 and Max 127. Default is 100). 4. Press ON to confirm or press DME and IR simultaneously to abort the function and leave the menu. 13 User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ CALIBRATE – CALIBRATING THE ULTRASOUND To obtain maximum accuracy the Vertex IV should be calibrated. 1.

Make sure that the Vertex IV has the same temperature as the surrounding air. Use a measuring tape to measure the exact distance of 10,0m/32.8 feet. Place the transponder at the end of the measured distance. Make sure the Vertex IV is OFF. Activate the T3 transponder by holding it within approx. (2 cm/ 1 inch) from the ultrasound speaker in the front of the Vertex IV and press DME. Await two (2) short beeps from the transponder. The T3 transponder is now active and will stay in that mode until it automatically turns itself off after 20 minutes of inactivity. To turn the transponder off, actively repeat the procedure above and await four (4) short beeps. 6. Press DME and IR simultaneously to turn the Vertex IV off. 7. Place the Vertex IV (front towards the transponder) exactly 10 m/32.8 feet from the front side of the transponder. 8. Press ON to activate the instrument. 9. Choose CALIBRATE and press ON to confirm this choice. 10. When the digits 10.00 are shown in the display the calibration of the Vertex IV is done. 11. Simultaneously press DME and IR to leave this menu. 12. See www.haglofsweden.com for a filmed step‐through sequence featuring the calibration process 10,00 m 
It is important that the temperature sensor in Vertex IV has been given enough time to adapt to the ambient temperature. If the Vertex IV is carried in an inner pocket, it will take more than 10 minutes for the instrument to adapt. Example: The Vertex IV is carried in an inner pocket with a temperature of +15°C. The ambient temperature is ‐
5°C. The measurement result will instead show 10,40 m instead of the correct 10,00m. the temperature dependent error at 10,00m is approx. 2 cm/°C. If the calibration is made before that the temperature sensor has stabilized, the error will be permanent. A correct result can be displayed for a short time, only to become incorrect soon after. 14 User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ BATTERY The Vertex IV uses an alkaline or rechargeable 1,5 V AA battery, that is placed under the battery lid with the + pole inwards. A battery symbol in the display shows battery status with 4 icons (100%, 75%,50%, 0%).Under normal conditions the battery will last for weeks or even months. Frequent use of the Bluetooth function will reduce the battery capacity. TO MEASURE DISTANCES ULTRASOUND Ultrasonic signals are used to perform measurement operations in the forest, in dense terrain and circular sample plots. SOME FACTS ABOUT ULTRASOUND Ultrasound pulses travel with different speed depending on external circumstances. In open terrain and without obstacles between the Vertex IV instrument and the transponder, distances up to 40 meters and more can be measured. With the transponder set to measure in a full circle, the distance will be approx. 20 meters. Always calibrate the ultrasound in the current temperature and make sure that the Vertex IV has the same temperature as the ambient air. A built in sensor compensates for temperature variations. To obtain maximum precision it is recommended to control and if necessary calibrate the instrument periodically, preferably daily. DME –DISTANCE MEASURING WITH ULTRASOUND 1.

The transponder has an ultrasonic transceiver that communicates with the Vertex IV instrument. The transponder can be used for direct measurements and to measure in a full 360° circle, suitable when working in circular sample plots. A monopod plot staff and adapter/spreader are used to place the transponder in the centre of the sample plot. For directed measurements the transponder is pinned to the tree with a small metal hook on the backside of the transponder. The T3 transponder emits a signal that indicates if the transponder is ON or OFF. The transponder has no switch and the Vertex IV instrument is used as remote control. The transponder will automatically turn itself off after approx. 20 minutes of inactivity. The Transponder T3 uses a 1,5 AA alkaline battery, placed under the battery lid. Transponder housing Battery lid Ultrasonic transceiver ADAPTER/SPREADER The adapter/spreader and a custom plot staff is included in a Vertex IV‐360 configuration. The adapter enables measuremente in a full 360° circle, and is suitable to use in sample plot cruising work. PLOT STAFF ‐ MONOPOD The plot staff is used with the adapter for the transponder T3. The staff is telescopic, lightweight and height adjustable. 16 User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ BAF –BASAL AREA FUNCTION When you measure with a factor gauge or a prism, some trees can be obscured by other trees, hence preventing a correct basal area measurement. With the Vertex IV built in BAF‐function the minimum diameter for each tree is displayed when the distance from the plot center is measured with ultrasound. Start by setting the factor (BAF) that the factor gauge or prism has in the SETUP menu, see section SETUP. Measure the distance from the tree to the reference point with the DME function. The distance and a calculated minimum diameter (cm/inch) are displayed. The diameter of the tree is measured and should only be included/counted in the plot only if the diameter exceeds the diameter shown in the Vertex IV display. Selectable Basal Area Factors if metric: 0,5, 1, 2, 3, 4, 5, 6, 7, 8, 9. (m2/ha) Selectable Basal Area Factors (BAF) if feet: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50. (ft2/acre) If the terrain is inclining, the Vertex IV can compensate the minimum diameter, depending on the inclination. Use the ANGLE function to measure both distance and angle from the tree to the plot center, see section ANGLE‐horizontal distance with ultrasound. HEIGHT MEASURING WITH VERTEX IV The Vertex IV is an excellent instrument to measure heights, and especially tree heights. HEIGHT – TWO POINT MEASURING WITH ULTRASOUND Vertex IV provides different modes to measure heights. The current situation and surrounding can determine which mode is most suitable. 1.

It is now possible for external devices to connect with the Vertex IV. Data is sent when you press the IR button on the Vertex IV when you have measured a height, angle or distance. The Vertex IV will not disconnect the Bluetooth® connection even when the instrument is switched off. This means that that you can send data with Bluetooth® if turning on and off the Vertex IV without having to reactivate the Bluetooth® function. To deactivate Bluetooth®, change ’ON’ to ’‐‐’ in the BLUETOOTH® menu. When the Bluetooth® function is activated the Bluetooth® symbol is shown in the display as a reminder that the function is active. The Vertex IV will turn the connection down after approx. 20 minutes of inactivity. 
Note that the Vertex IV consumes more battery when the Bluetooth® function is activated. Do not forget to turn the function off when not in use, for example when moving between sample plots. To turn the Bluetooth® function off, simply change the ´ON´ to ´–´ in the Bluetooth® menu.

These are the ports in some common handheld computer brands: ALLEGRO COM6 is usually the internal Bluetooth® port. RECON COM4 is usually the internal Bluetooth® port. SIGN FORMAT BLUETOOTH The transfer rate (baud rate) and numbers of stop bits is determined automatically by the receiver. The number of bits per sign is 8 data bits and no parity. IR – COMMUNICATION Data can be sent by IR (Infrared light) to Digitech Professional/DP II Computer Caliper or to a special IR‐
receiver, which can be installed in a serial port (RS232). 1. Aim with the instrument IR‐eye to the IR‐receiver and press the IR button. The distance between the Vertex IV and the IR‐receiver should not exceed 10cm/4 inches for a successful transfer. SIGN FORMAT IR Data can be sent from all measuring functions within the Vertex IV. If necessary use settings baud 1200bps, 7 data bits, 1 stop bit and even parity. 21 User guide Vertex IV Vertex IV ENG rev 1.0, 2014‐03‐14 DÅ DATA FORMAT Data from Vertex IV is sent serial as text.
