1. Assemble the anemometer tower in the vicinity of the tree(s) to be assessed. Attach the anemometer on the top, and erect the tower. Wind velocity readings are sent to, and data is collected at the instrument box located at the bottom of the tower.
2. Start recording data by pressing the START button located in the instrument box.
3. Mount the inclinometer on the root collar of the tree to be assessed.
4. Mount the elastometers onto the trunk of the tree to be assessed. Connect them to the central unit.
5. Start recording data by pressing the START buttons located on the side of the instrument box.
6. Repeat the previous 3 steps if you have more inclinometers and/or elastometers want to assess multiple trees.
7. Record data for at least 3 hours (the longer the better).
8. After the recordings are finished, transfer the acquired data to a PC by removing the internal SD card or by switching the instruments to Wi-Fi mode.
9. Load the data into the DynaTree evaluation software and calculate the safety factor.

An instrument for measuring wind velocity at or near the tree to be evaluated. The closer to the better, but, depending on wind velocity DynaRoot may provide reliable data even with measurements taken several kilometres/miles away. The anemometer provides wind velocity data of sufficient frequency, Ideally the anemometer should be clear of buildings or other objects that may obstruct the wind, at a height of at least 10m.

An instrument affixed to the root collar that measures the inclination of the trunk in two perpendicular directions. The instrument provides very accurate inclination data with sufficient frequency.

An instrument attached to the trunk for measuring the micro elongation of the trunk.

A PC software for evaluating wind velocity and inclination. The data, recorded over a period of several hours, are transferred from the anemometer and inclinometer on memory cards or wirelessly via Wi-Fi. The software breaks the data down into shorter intervals, and calculates statistical parameters for each interval that are used for the tree stability evaluation.
