(ii) Calibration via ‘SETUP’ MENU
1 Ensure that steps 1 to 8 on page 22 have been carried
out prior to actual calibration.
2 Navigate to the ‘MENU’ screen by pressing the ‘MENU’
key.
3 Access the ‘Calibration Check’ screen by hitting the
‘CAL CHECK’ button.
4 The screen will then prompt, “Enter weight required
here”. Select the bin that you want to calibrate by
pressing the arrow key.
Enter the amount required. Hit ‘ENTER’ to continue
Remember to set and keep to consistant units.
Note that this is is only related to calibration and
weighing; it is not related to the sowing rate entered
on the startup screen earlier.
6 The machine will dispense the amount you entered
based on the current settings. If the product or seeding
rates are different from the last time the machine was
used then the amount metered may not be as expected.
If you suspect that the calibration container will overflow
then you can stop metering process by hitting one of the
5 keys along the bottom of the screen.
7 Once the machine has stopped the calibration delivery,
either because it has reached the amount you entered
or you forced it to stop, weigh the contents of the
container. Write down the amount exactly as displayed.
Do not round up or round down the value measured.
Scales must be accurate to 2 grams.
8 Enter the recorded value into the Operating Screen as
shown. Press ‘ENTER’ to confirm as requested.
Always use consistant units of measure ie grams or
Kilograms.
6 Press ‘ENTER’ again. The instrument will then calculate
the settings in order to correctly deliver the product. The
‘error’ value is only the difference between the new and
old settings. Subsequent recalibrations with the same
product will only report small differences.
7 Press ‘ENTER’ again to confirm and store the new
settings.
8 Repeat the calibration process. In this case, the ‘Error’
reported will be very small if any. Remember to press
the ‘ENTER’ key to accept the settings.
This repeat
calibration is especially important if the metering units
have been adjusted from very different values since the
last time the machine was used.
