TRANSFER OF THE THINNER END OF THE DIAMETER CURVE
(TOP, PULP WOOD)
−
The diameter curve can be inclined upwards or downwards at the
minimum end.
−
This inclination is necessary, when a check of the volume
measurement has revealed a deviation.
TRANSFER OF THE THICKER END OF THE DIAMETER CURVE
(BUTT END, LOG)
−
The diameter curve can be inclined upwards or downwards at the
maximum end.
−
This inclination is necessary, when a check of the volume
measurement has revealed a deviation.
NOTE!
If an error in the result of the measuring equipment is found in the
control measurement, the displayed diameter must be corrected by
transfer of the lower and upper end.
In pulp wood a 4 % error in the volume corresponds to an error of appr.
1 – 3 mm in the diameter measurement, when the average diameter
varies in the range 5 – 15 cm.
In logs a 4 % error in the volume corresponds to an error of appr. 3 – 8
mm in the diameter measurement, when the average diameter varies in
the range 15 – 40 cm.
