4. CALIBRATION
It is vital that an accurate scale for calibration
purposes is used to ensure accurate
application. The calibration lid is removed to
catch the product.
Calibration of the metering unit is done
statically without the fan running.
• The calabration handle rotates at a certain
number of revolutions (O) which is the
equivalent to 50 linear meters of travel.
Product is caught and weighed under
each metering unit.
• The number of revolutions of the metering
unit rollers is regulated by the ZeroMax
Gearbox:
NOTE:
Count the revolutions that the calibration handle makes while the planter runs over 50
meters. The calibration handle rotates theoretically 77 times per 50 meters.
The required calibration weight
(G)
can be calculated using the following equations:
A = Working width of planter in meters (Number of planter units x row spacing)
B = Catch distance (distance that the seed is collected, eg 50 m)
C = Suggested applications level in kg / ha
D = 10 000 (constant to determine value in hectares)
In other words:
G = A(working width) x B(distance) x C(kg/ha)
D(10 000)
NB:
Use an electronic scale that is able to weigh in increments no more than 5 grams.
EXAMPLE:
A = 5.77 m
B = 50 m
C = 120 kg/ha
G = 5.77 x 50 x 120 = 3.462 kg/ha (total weight measured over 50 m
)
10 000
