a)
If known, enter the numerical value directly
via the key pad, and confirm with
<Enter>
.
The figure is a calculated value, and
corresponds to how many metres are
travelled by the machine per impulse
from the ground wheel sensor. The sensor
transmits 360 impulses per revolution. If the
actual working circumference of the ground
wheel is known, the actual value of the
circular arc can be calculated –
but this is
not recommended
.!
The following method of measurement is
recommended:
b)
Determine a length of 100 metres with a
measuring tape, and mark it off with two
poles. Line up a fixed point on the machine
with the first pole, and set the machine

off as normal.
Do
not
sow during the measurement, i.e.
the fan does not need to be at its nominal
speed. Once in motion, the impulses are
displayed on the control panel. At the end
of the measured length, stop with the fixed
point on the machine as closely aligned
as possible to the second pole, and press
<ENTER>
. The display changes to
SPEED
SENSOR FACTOR
, the value is calculated
automatically and displayed immediately.
Pressing
ENTER
saves the value; pressing
ESC
allows a new test to be carried out.
When the speed factor value has been
saved, the display returns to SPEED SENSOR
FACTOR. Exit from this screen with
<ESC>
.
