Pre-Planting Seed Calibration Process (using CAL TEST function)
Continued
11. Note that the Drillmaster controller is not counting any seed but merely calculating a rate based on
row width and pulses from seed shaft sensor. The data entered in initial setup (Page 8), like row width
and rows per section, is very important to the operation of the controller. This data should be checked
periodically to ensure its accuracy.
12. Your Drillmaster controller should now be ready to go to the eld.
In-Field Seed Calibration Process
This procedure will be used to nd a more accurate Meter Cal value during normal eld operation.
You could place a known weight of seed in the drill and drill until it is gone during this process.
If you have access to a scale, you could weigh the drill full of seed, then after drilling some
amount. You will need to use some procedure to determine the actual weight of seed dispensed.
1. Clear a weight counter by selecting the Weight position and pressing “-“ key for 1 second while in HOLD.
2. Operate the drill in the eld. The measured seed weight will accrue in the weight counter you reset in
step 1.
3. Find the total actual weight of seed dispensed.
4. Enter Calibration mode by pressing CAL for 1 second. Red light will come on steady.
5. Turn dial to the METER CAL position. The current METER CAL will be displayed.
6. Push CAL key to toggle to the weight. Use the “+” and “-“ buttons to adjust the weight to the actual
weight drilled. The DrillMaster will automatically change the METER CAL value.
7. Push CAL key to toggle back to the new METER CAL value. Make a note of the new value in your
operators manual for future reference.
8. Press and Hold “CAL” until red light is off to exit calibration. This saves the new calibration settings.
