SPEED SENSOR CALIBRATION
The purpose of this procedure is to match the
console to the distance-measuring device you
are using. This Distance Calibration procedure
will allow you to easily calibrate the Speed Sen-
sor.
In lieu of doing the Distance Calibration proce-
dure a known PULSES/FT calibration number
may be entered manually during Set-up. An ex-
ample would be the 2.00 Pulses/Ft used with the
HINIKER GPS Speed Sensor.
Both Spray and NH3 modes have their own
PULSES/FT calibration number. That means you
need do the Distance Calibration procedure for
each mode. You may however enter the Calibra-
tion number manually while in Set-up for either
mode.
The Distance Calibration Number is calculated
by having you drive a predetermined distance,
500 feet in this case, while it counts the pulses
from your speed sensor. It then divides the total
pulses by the total feet (500). This is the Pulses/
Ft calibration number used by the console to cal-
culate Speed and Area.
This procedure works very well and provides
an accurate calibration number in most cases.
There are some things to consider when using
certain types of Speed sensors. This is because
the console starts counting pulses as soon as
you press the SET key, any pulses generated,
will be counted whether you are moving or not.
The console will count ALL pulses between the
PRESS TO START and the PRESS TO END key
presses. The second thing to consider is that the
Speed sensor must start sending pulses imme-
diately when you start to drive. Any delay will
cause the pulse count to be off.
RADAR:
Some radar may output pulses while the vehicle
is sitting still. This is usually caused by vibration.
To prevent this some models of radar prevent
the outputting of pulses below a certain MPH.
Both situations will cause inaccuracies when do-
ing Distance Calibration.
To check for vibration do the following: Follow
the procedure to do Distance Calibration. When
the display shows “PRESS SET TO START”
make sure the tractor is NOT moving then press
SET. The display will show “DRIVE 500 FT” until
it sees pulses. If this changes to “PRESS SET
TO STOP” then you are receiving pulses, prob-
ably from vibration at the radar. If the display still
shows “DRIVE 500 FT” then start driving, the
display should change immediately to “PRESS
SET TO STOP”. If there is a delay you may be
missing pulses.
To overcome these problems use the following
procedure:
When the display shows “PRESS SET TO
START” line up back of the start flag and start
driving. Press the SET key as you pass the start
flag. Drive at a constant speed then press SET
as you pass the stop flag. Do not slow down until
after you pass the flag.
GPS:
It is not necessary to perform the Distance Cali-
bration when using the HINIKER GPS Speed
Sensor. Enter 2.00 Pulses/Ft for the Distance
Calibration number during Set-up.
