Step 7: Please check the table “Delta %” to ensure that your measurements are reliable. This
table displays the standard deviations in per cent. The values should be < 10%. If
values are higher, please repeat the measurement for that sensor. In the case of the
table below, the values between sensor 3 and 11 still show a very high coefficient of
variation. Repeat knocking on sensor 3 until the value shown is below 10. Usually 5-10
measurements should
be enough to receive
reliable results. In
some case the
number may be
higher.
Step 8: Stop the measurement by clicking on the red square.
Step 9: We recommend doing a photo documentation of the position of the sensors. This can
be very helpful in case any questions or doubts concerning the measurement occur later
on.
Step 10: Remove the sensors and sensor pins from the tree.
CAUTION: Always remove sensors from sensor pins before removing them from
the tree. Never remove the sensors pins with the aid of the
sensors as this can break the sensor!
