Diameter Dendrometer Large – Type DD-L1 installation is taking place shortly before frost period, the sensor rod should be pushed in by 5 mm. At frosts the stem diameter can shrink considerably. 4.3.5 Re-tighten all screws firmly. 4.3.6 Fix the cable onto the tree stem/branch by using a cord, such that the sensor is pro- tected from any accidental pull/drag on the entire cable length.
