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

=0.80951.80

=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
				H1	H2
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.
