19 i-CON Calibration (Page 1 of 2)
You will need a suitable container to collect the product or seed when calibrating, and an accurate set of
scales which weighs in grams
At the machine
1.
Air Force Models only
switch the fan OFF at the junction box
2. Position a suitable container to collect product whilst calibrating
3. Place a few kilograms of seed in the hopper
At the ICON instrument
1. Switch the head unit ON via the left hand side push
button – wait until the start-up routine has finished and
displays the main “home screen”
2. Scroll through to the Setup Menu and select the
Applicator Icon
3. Adjust the implement width accordingly - refer to the
RDS manual, page 25, section 3.3, Set Implement
Width
4. Ensure the correct application rate is
entered – select and adjust accordingly,
refer to the RDS manual, page 21, section 3.1, Setting the Application Rate
5. Ensure the feed roller setup is appropriate for the intended product or seed type, application rate and
forward speed range for application
6. The instrument calculates the calibration factor from the working width, target application rate, and the
metered weight delivered whilst calibrating. If however as a result of the calibration routine, you find that
you cannot achieve your desired field speed, displayed in the top right corner of the screen, then
re-configure the feed roll assembly and repeat the calibration procedure
7. Prime the feed rollers with product by pressing and holding briefly the prime button on the junction box
- this will ensure a higher initial calibration accuracy, empty the contents of the tray back into the hopper
8. For an
Auto Calibration
from the Product Setup page, touch
9. Touch and enter the quantity that you wish to dispense for calibration purposes. You can enter
the quantity in grams if preferred. The CAL factor will however, still be calculated in kg/rev
10. Touch on the screen page
11. After
the key the motor runs at the calibration speed (calculated from the Simulated Forward
Speed, Width, Application Rate and current calibration factor)
12. The dispensed weight (based on the current calibration factor) is displayed
13. Weigh the product dispensed and then enter the measured weight, and press
14. A new calibration factor is then re-calculated and displayed
15. Your in field min and max speeds will be displayed as per the
image to the right hand side. If you find that you cannot achieve
your desired field speed, then re-configure the feed roller assembly
and repeat the calibration procedure (see pages 17 and 18 for
more details)
16. Touch to save the new factor, it is advised to repeat the
calibration 2 more times to ensure accuracy
