Basic Calibration Procedure (Continued)
Hectaremeter Settings (Continued)
Example 1 :
Computronics 1100 Area Meter Setup for 10 Run Vineyard Seeder
(when fitted with 155R13 tyres)
(Referring to Sowing Width Table Above)
10 Run Machine x 180mm Spacings = 1.80m Sowing Width
Drive Ratio From Wheel to Sensor = 0.8095
Rolling Circumference of Tyre = 1.80m (Refer Page 16)
H1 - Distance per Pulse =
Circumference of Tyre
Drive Ratio
=
1.80
0.8095
= 2.224m
Therefore:
H1 Setting = 2224mm Distance Travelled per Pulse
and H2 Setting = 1.80metres Effective Sowing Width
Please record here the settings for your machine in case you are
required to re-enter them at some time in the future.
It is advisable as with all things electronic to have a backup of your
totals. We suggest you record these on a daily basis in a notebook or diary.
