After the motor has been stopped with the white button the screen will show the expected
weight.
Then enter the ACTUAL weight dispensed using the keypad (Fig.43) and press

again for the instrument to re-calculate and display the new calibration
factor in kg/rev, the error %, and the maximum forward speed that is permissible based on
the application rate set for the product (fig.44).

This entire procedure should be repeated as many times as necessary until there is an
acceptable error. (2 – 3 times is normally sufficient)
It is recommended to reset the PART TOTAL to zero before commencing drilling. This will
enable you after drilling an area, to quantify any error in the calibration factor by logging the
theoretical amount of product used against a known amount used (a whole bag for example).
7.3.1 ORGA Metering Setup
Before any calibration test is performed the ORGA Metering Unit must be set up for the seed required.
Larger harder seeds like peas and beans do not require the nylon insert in the orga housing. This is simply
removed by two bolts. The setup should be based on the required seed rate, working width of the drill as
well as driving speed.
To ensure successful drilling, be sure to take into account the specific weight of the type of seed. It may
also be beneficial to change the coulter outlets from the standard twin row tip to a single outlet type.
