All entered values and gathered data are stored in a memory, if power,
deliberately or not, is cut off.
LH 1000 can be used on the following:
! TRACTORS
! COMBINE HARVESTERS
! MOBILE SPRAYERS
IN FACT ANY AGRICULTURAL MACHINE
!
On the following pages you will find a description of how to encode, use, test and
fit your LH 1000.
SECTION FUNCTION
With this function the working width is divided into four equal sections. This section
function reduces the area measured by the number of sections that have been
switched off. This function works as follows:
! Pressing the numerical key "1" will reduce the working width to 1/4 of the
encoded working width.
! Pressing the numerical key "2" will reduce the working width to 2/4 of the
encoded working width.
! Pressing the numerical key "3" will reduce the working width to 3/4 of the
encoded working width.
Full working width can be achieved manually by pressing the numerical key "4" or
automatically when the implement sensor is activated.

ENCODING THE LH 1000 (FUNCTION SET 1)
There are two figures that need to be encoded before the LH 1000 can be used. It
is important that the following are accurate as these are fundamental for correct
operation of the monitor.
WORKING WIDTH
The working width of the implement being used is encoded here:
Step Key Procedure
NCODING THE
LH 1000
1
Press the working width key.
2 Encode the working width in centimetres using the numerical
keys. Ensure that overlaps are accounted for. If the working width
is unknown, then drive 5 bouts and measure the distance between
the first and the last, then divide the distance by 5.
3 The encoded value is stored automatically until another working
width is encoded; press any other key to leave this encodement.
FORWARD SPEED CALIBRATION (WHEEL CIRCUMFERENCE)
To ensure that the LH 1000 can accurately measure forward speed, which is also
used for area calculation, the wheel circumference must be measured and
encoded. The procedure for this is as follows:
WHEEL CIRCUMFERENCE WITH MAGNETS FITTED TO THE WHEEL
Step Key Procedure
1 Make a mark on the field and on the tire on the wheel with
magnets fitted.
2 Drive slowly forward until the wheel has turned 10 times.
3 Make a mark on the field again.
4 Measure the distance between the 2 marks on the field and divide
this distance with 10 the result being the effective wheel
circumference.
5 Divide the effective wheel circumference with the number of
magnets fitted to the wheel.
6
Press the wheel circumference key and an >0< appears on the left
of the display indicating that "wheel circumference" has been
selected.
7 Encode the result (from steps 1 to 5) in centimetres using the
numerical keys.
8 The encoded value is stored automatically until another wheel
circumference is encoded; press any other key to leave this
encodement.

PERATORS
Example:
In the following example we assume that we use a tractor with a wheel
circumference of 500 cm and 2 magnets fitted to the wheel:
Measurement shows that the effective wheel circumference = 500.6 cm.
There are 2 magnets fitted so the effective wheel circumference needs to be
divided with 2.
500.6 : 2 = 250.3 cm
Encode this as 250
WHEEL CIRCUMFERENCE WITH A MAGNET FITTED TO CARDAN SHAFT
A magnet can be fitted to the cardinal shaft if, for some reason, it is not possible to
fit any magnets onto a wheel. To determine the value to be entered as the "wheel
circumference" use the following procedure:
Step Key Procedure
ITTING MANUAL
& F
1
Enter a working width of 9999 as described on page 7.
2
Press the area total key.
3 Drive slowly forward until 1 appears on the display STOP
IMMEDIATELY.
4 Make a mark on the field and on the tire.
5 Drive until the display changes from 10 to 11 STOP
IMMEDIATELY.
6 Make a mark on the field again.
7 Measure the distance between the 2 marks on the field. Divide this
distance with 10.
8
Press the wheel circumference key and an >0< appears on the left
of the display indicating that "wheel circumference" has been
selected.
9 Encode the value determined in steps 1 to 7 using the numerical
keys.
10 The encoded value is stored automatically until another wheel
circumference is encoded; press any other key to leave this
encodement.
Remember to encode the correct working width for the implement again!

AREA TRIP & TOTAL COUNTERS
The area counters start and stop automatically when the implement is in work/not
in work (implement sensor) and continue to count regardless of what other
function in function set 1 has been selected. Area is not being measured if an >r<
is displayed on the screen.
Key Function
Trip counter:
Pressing this key displays the area covered in ha with 2 decimals from 0
to 99.99 ha and with 1 decimal from 100 to 999.9 ha.
Pressing this key for min. 3 seconds resets the counter.
Total counter:
Pressing this key displays the total area covered in ha with 2 decimals
from 0 to 99.99 ha and with 1 decimal from 100 to 999.9 ha.
This function can be used to sum area covered for, i.e. a month.
Pressing this key for min. 3 seconds resets the counter.
FORWARD SPEED
Key Function
Pressing this key displays the present forward speed in kilometres per
hour with 1 decimal.
Forward speed is always displayed when the monitor is switched on.
An “r” on the left-hand side of the display under this function, indicates
that the area override sensor has been activated.
Forward speed is zeroed after approx. 8 second after stopping.

FITTING THE LH 1000
FITTING THE MONITOR
Fit the monitor where it can be easily seen by the operator whilst driving. We
recommend on top of the instrument panel or to the right-hand side of the cabin
above the lift operating handles.
The form supplied with the LH 1000 can be stuck in the cabin so that the noted
values can easily be found and re-entered if necessary.
POWER SUPPLY
The supplied power cable should be connected to 12V so that the monitor is
switched on and off with the ignition (ignition live).
The power cable wires should be connected thus:
F
ITTING THE
LH 1000
Blue = +12V (power)
Brown = 0V (ground)
IMPORTANT! Never incorrectly connect these wires, as the monitor will be
damaged instantly.
GENERAL WIRING
Lead all cables so that they are as protected as possible. Wherever possible lead
the cables alongside existing cables, hydraulic pipes or similar, and fasten with the
supplied cable ties.
Beware of moving parts and heat sources, e.g. exhaust pipes.
Cables in the cab that cannot be hidden should be fastened with adhesive cable
fasteners, clean the surface thoroughly with, i.e. alcohol before sticking the cable
fasteners to the surface.

FITTING THE WHEEL SENSOR
We recommend fitting the wheel sensor to the tractors right back wheel. See the
following diagram.
The distance between the magnets and the wheel sensor must not be greater than
5 mm. Fit 2 magnets if the effective wheel circumference is larger than 250 cm.
NOTE! The magnets must be fitted with equal distance otherwise the
displayed forward speed will be erratic.
The magnets can, i.e. be fitted next to the wheel bolts.
Always fit the magnets with the yellow dot facing the sensor.

The implement sensor can be fitted in other positions (PTO handle, hydraulic
cylinders, other handles, etc.). There must be movement of minimum 50 mm. The
distance between the sensor and the magnet must not exceed 5 mm.
An electrical signal from, i.e. a sprayer switch box, etc. can be used as the
implement signal. The signal must change to 0V (ground), when the implement is
not working.

ERROR WARNING
To ensure that data will not be lost, the LH 1000 has a built in error indication:
If your LH 1000 displays this error warning, the supply voltage to the monitor is too
low. Check therefore the power supply to the monitor (both + and -).
