To make sure fertiliser is being metered and sown at the required rate it is necessary to take
and weigh a sample from the metering unit. This weight is then entered at the Artemis
Control Unit which will calculate and adjust for any error-i.e. the error being the difference in
fertiliser weight between what the control unit calculated would pass through the metering
system per revolution and what was actually weighed. With the fertiliser hopper empty follow
the method below to calibrate your drill:
Low Fertiliser Application Rates
Standard Fertiliser Application Rates
1) At the metering unit wind in the handle until it is fully closed (the O position) and make sure
the separation slider plate is fully open.
2) Turn red lever to intersect drive shaft key
way (Figure 24.1).
Turn red lever so that it is not in the drive shaft
key way (Figure 24.2).
3) The fan deflector Must be set parallel to pipe for all seeds (Figure 25)
4) If necessary, ensure that the white and red gears are aligned by pushing the white button
so that the red cog will insert into the grey/white cog and push into place. This setting should
always be used and gives high speed gearing at all times.
5) Wind out handle to about 15 on slider (20
max) see Figure 23. For more comprehensive
details on slider positions consult Appendix D
at the rear of the manual.
Wind out handle to about 80 on slider. The
handle may be wound out to 100 to achieve
higher speeds (see Figure 23). For more
comprehensive details on slider positions
consult Appendix D.
6) Open the hinged flap at the bottom of the Venturi cover. Place a bucket under the
metering unit, prime the metering unit by pressing the white button and hold for three
seconds to start the metering motor, this ensures the unit is full of fertiliser prior to an
automatic calibration. Press the white button again and hold for another three seconds to
stop seed flow. Empty the bucket.
7) To commence the automatic calibration procedure, position a bucket which you have
accurately weighed in its place under the metering unit. Press the white button and hold for
three seconds, to start the metering motor. When you have obtained a good sized sample,
press the white button again and hold for another three seconds to stop seed flow, (the
motor may not stop immediately).
8) Weigh the bucket with the sample in accurately (Grams for small amounts of fertiliser,
kilograms for large amounts of fertiliser).
