Pre-Planting Seed Calibration Process (using CAL TEST function)
Continued
Calibration Mode
1. Turn Power toggle to ON and RUN/HOLD toggle to HOLD. Turn all Section toggles on that you wish to
test.
2. Enter CAL mode by pushing and holding the CAL soft key until red light is on steady.
3. Move center rotary switch to METER CAL and verify that the cal number is correct for crop and slot
width you are testing.(See Page 9.)
4. Move center rotary switch to CAL TEST and push + soft key activate. Display should now show 1.00. A
one pound test sample will be dispensed from each seed drop.
5. Move center rotary switch to TEST SPEED and use + or - soft key to select a speed that is close to the
speed you plan to operate in the eld.
NOTE: Test speed must be the last data entered before starting calibration test.
6. Turn on hydraulics and move RUN/HOLD toggle to RUN. The motors should now run until one pound of
seed is dispensed. Do not switch RUN/HOLD to HOLD or you will not be able to complete Step # 8.
NOTE: The motors will automatically stop after one pound.
7. Gather samples caught into one pre-weighed container and weigh with scale provided with drill. Subtract
weight of container from total weight then divide by number of seed drops caught. This is your actual
sample size caught.
8. At the Drillmaster controller move the center rotary switch to CAL TEST. It should still show 1.00 on the
display. Use the + or - soft keys to adjust display to actual sample size caught.
NOTE: This is adjusting the METER CAL number at the same time so a high calibration number may take
some time to adjust.
9. Once adjusted, put RUN/HOLD toggle to HOLD and push and hold CAL soft key until red light is no
longer steady on. The new calibration number should now be saved.
10. Push and hold CAL soft key until red light is steady on. Move center rotary switch to METER CAL.
Write down this new meter cal number for your drill slot width and seed.(Space provided on Page 13.) It is
recommended to re-run the calibration test to verify accuracy of results.

10. Set the slot opening on each drill section for the desired crop.
11. Pour several pounds of seed over seed drops which will be used. It is recommended to sample at least
two drops per drill section. Disconnect these drop tubes and position a catch container under each seed
tube.
NOTE: The more seed drops sampled per section the more accuracy you can expect from this test.
Accuracy of plus or minus 4 to 6% is a very acceptable test. If you do not run a calibration test the
standard calibration numbers (Page 9.)have an accuracy of plus or minus 10% at best
