Pre-Planting Seed Calibration Process (using CAL TEST function)
This procedure is used prior to field operation. These steps will determine a more accurate
Meter Cal value for your exact drill settings with your seed.
Preparation
1. Set the slot opening on each drill section for the desired crop.
2. Fill drill with seed.
3. Disconnect a few or all drop tubes on each section.
4. Position catch container under each drop.
Enter Calibration Mode (switch controller to hold and press the “CAL” button until the red light is solid)
1. Turn Rotary Position Switch to “Cal Test”, “Off” appears in the display, press “+” to activate the Calibration
Test mode “1” appears in the display (a one (1) lb sample will be dispensed from each opener).
2. Turn Rotary Position Switch to “Test Speed”.
3. Use “+” to enter normal operating speed.
4. Turn Rotary Position Switch back to “Cal Test”.
5. Switch from the hold to the run position and turn all section on. The “Cal Test” will begin. The display will
count up the measured sample weight and automatically turn off at one (1) lb.
6. Combine the samples and weigh, then calculate the average sample weight.
7. Adjust the controller measured weight (1 lb) to the actual average sample weight. Use the “+” and “-“ buttons
to adjust the weight.
8. Press and Hold “CAL” until red light is off to exit calibration. This saves the new calibration settings.
9. Re-run test to verify calibration is accurate.
10. Re-enter calibration mode and turn dial to Meter Cal. Make a note of the Meter Cal for your drill and seed
in the DrillMaster manual.
