Step 4. Rotate calibration handle for the correct
number of turns to simulate 1/20
th
of a
hectare (see table page 14). Rotate
handle anti-clockwise.
Fig.20 Calibration handle rotates anti-clockwise,
as shown by the arrow.
Step 5. Weigh sample taken on scales supplied.
When using scales use the scale box as
the container. Place box on top of scales
before switching on. Check that the
scales are set at zero before weighing
sample.
Fig.21 Scales.
NOTE: It is the responsibility of the
operator to check the accuracy of the
scales on a regular basis.
Step 6. If the result is too low you will need to
increase the setting on the variator. If too
much material was collected the reverse
applies. After making the adjustment you
will need to retest the system following
steps 4 and 5.
NOTE: It is recommended that when adjusting
the variator setting the operator goes past the
desired setting (higher rate) a short distance and
then rotates the handle back to the required
setting. This method of adjustment will ensure
that there is no slack in the cable if a cable is
fitted.

IMPORTANT When the
calibration procedure is completed
close the bottom door of the pasture
planter and engage the drive pins on
the main bins to allow the drive
system to operate normally.
