On fields with slippage, the calibration value [pulses/100 m] deviates from the standardized calibration
value. This also changes the number of crank turns in the table (Fig. 71).
If the calibration value you have determined differs from the standardized calibration value in the table
(Fig. 71), recalculate the number of crank turns for calibrating the seed rate (see below).
Calculating the crank turns to calibrate the seed rate
Crank turns = Crank turns (from table) x
Determined calibration value [imp./100 m]
Table value [pul./100 m]
Then perform the calibration test with the calculated number of crank turns.
Example:
Seed drill: ....................................................................... D9 3000 Super
Working width: ............................................................... 3.0 m
Tyres: ............................................................................. 180/90-16
Crank turns (table value, Fig. 71) .................................. 38.5 (on 1/40 ha)
Pul./100 m (calibration value, standardized) ................. 740 [pul./100 m]
Pul./100 m (calibration value, determined): ................... 710 [pul./100 m]
Crank turns = 38.5 x
710 [imp./100 m]
= 37.0
740 [imp./100 m]
Calibrate the seed rate at 37.0 crank turns.
