-        For detecting size and location of active fungi attacked regions

-       It works based on electric resistivity measurements

-       Up to 32 sensors around the trunk

-       Seasonal and daily changes can be visualised

-        Resistivity increases/decreases if there is a change in the ionic concentration

-        Fungi attacks even in very early stages may be determined

1. Place the resistivity meter onto the tree.

2. Measure the circumference and decide the proper     shape（circular, elliptic or irregular）. Place the electrodes onto the     tree at the proper positions or measure their positions. Enter the data to     the computer.

3. Start the measurement on the computer. During the     measurement do not touch the tree. Do not measure other conditions     parallel to the resistivity measurement.

4. Choose triangulation parameters and run the     iterations. The program will calculate the resistivity map of the selected     cross section.
