B.6 Calibration test
For precise control of the discharge amount we recommend running a new cali-
bration test every time you change fertiliser types.
Run the calibration test:

Before spreading for the first time.

If the fertiliser quality has changed greatly (moisture, high dust content,
cracked grain).

If a new fertiliser type is used.
The calibration test must be conducted (with engaged PTO shaft) at a standstill
or during travel over a test section.
B.6.1 Determine nominal output volume
Calculate the nominal output volume before starting the calibration test.
Calculate exact ground speed
The exact ground speed must be known to calculate the nominal output volume.
1. Drive the half full solid fertiliser broadcaster over a 100 m distance in the
field . Note the time required.
2. Read the exact ground speed on the scale of the calibration test calculator.

NOTICE
The solid fertiliser broadcaster AXIS 20.1 Q is tested for calibration using the
electronic control system.
The calibration test is described in a separate operator's manual for the elec-
tronic control system. This operator 's manual is part of the electronic control
system.
