Calibrating The Control System
To ensure the seed is planted at the correct spacing the control system will need to
be calibrated. The system should always be re-calibrated when changing seed size.
To calibrate the system:
1. Press the icon . The ‘constant’ screen is displayed (see fig 51).
2.
Using the + and – icons set the constant to 4.0.
3.
Set the planter into work and measure the distance between 11 seeds.
4.
Divide the distance by 10 and compare the result with the desired seed
spacing.
5.
If the spacing is too small decrease the ‘constant’. If the spacing is too large
increase the ‘constant’. Always adjust in small steps e.g. 0.1.
6.
Repeat the procedure until the correct seed spacing is achieved.
