CALibrATiOn PrOCESS
Calibration process
As seed varies greatly in specific weight, size, shape and dressing
the values given in the Seed Chart are only a guideline.
For this reason a calibration test must always be performed. In case
of deviation, re-calibrate the device using a different transmission
setting.
The new „correct“ transmission setting can also be determined without
the Seed Chart, using the values of a first calibration test (with random
transmission setting). (Use the „sowing disc“ supplied,
Fig. 40
).
Example: Set seed rate: 160 kg/ha
calibrated at 120 kg/ha with transmission setting 0
160 kg/ha = ?
120 kg/ha = 0
Transmission setting (0) x Set seed rate (160)
Calibration seed rate (120)
(40 = new „correct“ transmission setting)
The „Vitasem“
may be calibrated during standstill – without lifting.
Ensure machine is horizontal. (top edge of hopper side)
Close unused shutters.
Tramlining control must not be switched on (all sowing rollers
rotate).

Place emptying trays on seed guide rail (
41/1
) – see „Emptying“
page 8.
Change back after calibration:
- return seed guide rail to upright position/lock in,
- hook in emptying trays
42/1
and lock at
42/2
.
- Fill in seed (approx. half of the normal amount).

Adjusting seed quantity per hectare
The Calibration Process (Abdrehen)
* Remark:
In German word usage it is normal to use the term
„Abdrehen“ (which basically means turning the dosing
device by hand) instead of „Kalibrieren“ (meaning to
calibrate, electronically). In this manual we use the term
„Kalibrieren“ in order to avoid any misunderstandings with
text translations.
In principle this also applies to terms such as “calibration test”
and “calibration shutter”.
So-called ”calibration
process” establishes
what quantity (kg) of
seed per hectare will
be sown by adjusting
the dosing device
accordingly. Doing
this enables the dosing
device on the seed drill
to be adjusted exactly
to the desired seed
quantity.
