Introducon
Congratulaons on the purchase of your EC10 Platemeter. This platemeter is a
highly engineered precision device for measuring the average height of pasture
relave to density of the pasture.
This is directly relave to the quanty of dry maer present (kilograms of dry mat-
ter – kg DM/ha).
Your platemeter will become an invaluable tool in your farming operaon for day-
to-day feeding decisions and long term feed budgeng.
Important safety note
Read and understand all the instrucons before using the platemeter. A copy of
this user guide can be downloaded from www.jenquip.co.nz or www.nzagriworks.
co.nz
Your platemeter is designed only for measuring pastures. Use it for no other
purpose (e.g. it is not a walking sck.) This platemeter has been manufactured
using quality materials and techniques, however, if faults do occur, have them
corrected before you use the platemeter.
Be careful around electric fences. Parts of the platemeter will conduct
electricity!
Store the plate correctly. Be careful that the wind does not blow the plate away. It
is not to be thrown.
Water blasng or submerging the unit will void the warranty.

Assembly Instrucons
The platemeter is supplied in three parts:
The plate
The plate sits on top of the pasture to establish average height and density. The
area-to-weight rao of the plate has been carefully calibrated.
The rod with meter
The grooved rod allows pasture to be measured in 0.5 cm intervals (clicks). The
rod includes the electronic meter.
The handle
Aach top handle to the rod. Ensure that the rod does not fall through the coun-
ter as this will damage the gear and void warranty.

Handle assembly instrucons
Screw top handle onto the top of the
grooved rod where it comes out of
the counter.
Put 4 drops of thread locker into the
female end.
Screw threaded rod extension into grooved
rod and do up rmly by hand,
wiping o any excess thread locker that may
have leaked out with a dry cloth. Do not use
tools as this will damage the grooved rod.
Refer to the handbook for zero calibraon
before use.
Grooved Rod Extension (for the
400mm model)
Turn upside down and slip o the O ring.

Operang the platemeter
Switching the unit on and o
The platemeter is switched on and o using the
black switch at the back of the unit. O is in the
‘down’ posion. When the unit is o there are no
numbers displayed on the LCD screen.

Front display buons
The funcons of the EC10 are dened by the four buons
on the front of the unit.
The words in BOLD type (see below) are the primary
funcons. Acvate by pressing the buon briey. Acvate
the secondary funcons (in normal type, see below) by
holding the buon down unl the funcon operates.
Up/Down arrows used to scroll back and forth in some opons
When the Count buon is pressed the number of readings is displayed.
A “C” will show on the le side and count on the right. Hold the buon
down to view menu of further opons.
Height displays the average height of readings in clicks (0.5cm).
Pressing Reset will save the average height to memory and reset all data
ready for the next paddock.

Zero Calibraon
To ensure that the platemeter accurately measures the compressed height of the
pasture the platemeter must be calibrated. This requires seng a base level of
zero so that measurements can be benchmarked against this. If the counter does
not return to zero aer each “plonk” it will not record the measurement – hence
the counter will not beep.
If the counter is removed from the grooved rod or receives a severe knock it may
jump a groove on the steel sha which will put the counter out of calibraon.
It will need to be recalibrated.
To do this, work through the following steps:
1. Ensure the plate is fully down (place on a rm at surface) and the unit is
switched o.
2. Hold the “Count” buon while switching the unit on. The display will
change to “CAL” briey and display a colon (:) followed by a number. Let’s
assume you see “.5” when you switch on. Proceed as follows:
3. The colon signies that it is in ne calibraon mode. Remove the
protecve rubber bung by levering it out gently using a at-bladed
screwdriver. Use a at bladed screwdriver and
turn the plasc or steel sha within the cog
an clockwise, unl the display reads “0”.
NB: the cog and steel sha must remain
staonary. DO NOT TURN THE SHAFT BEYOND
THIS POINT OR YOU MAY DAMAGE THE
POTENTIOMETER. Once the counter reads
zero, move the counter up the full length of
the sha. The colon will disappear once it
passes 9 and enter “clicks” mode. At the full height the display should
read approximately “50” which is 50 half cenmetres. The counter has
now been calibrated successfully.
4. Switch o when you have nished, and then back on again without
pressing any buons.
5. Test the zero calibraon by raising and lowering the plate several mes.
A beep should sound and the kgDM/ha displayed as the plate falls. If it
does not, repeat the steps above and retest.
If calibraon fails to hold, then the potenometer, which the cog drives, may
be damaged and will need replacing. This can occur with excessive wear, oen
compounded by dust and dirt entering the dry bearing of the potenometer.

Start up/self test
Switch the unit on. It will beep and show “EC10” in the display panel. If the baery
needs recharging it will beep 3 mes and “lo” will display on the panel. The
current formula in use will be displayed next with the “+” part of the equaon rst
(default 500) and then the “x” part second (default 140).
The kgDM/ha calculaon will be displayed based on that formula and any other
readings stored in the memory.
To clear the readings, press and hold the Reset buon unl the display shows 0.0
The unit has one default plate equaon (built into the chip and cannot be replaced
or edited) and one custom (user editable) equaon. This equaon is typically used
in New Zealand between April and September.
Dairy Pasture (reasonably consistent rainfall areas height reading x 158 + 1000 •
= Cover (kg DM/ha)
Dairy Pasture (moderate rainfall periods height reading x 158 + 200 = Cover •
(kg DM/ha)
Sheep pastures: height reading x 158 = Cover (kg DM/ha)•
The platemeter also provides an opon for selecng your own equaon or those
recommended by consultants. Your platemeter will be set up for the Dairy NZ
recommended equaon for autumn/winter months.
Entering the Factory Default Formula
While the EC10 is switched on, hold down the ‘Formula’ buon. The display shows
‘F_ _ d’ Press the ‘Reset’ buon briey. The display will then show (500) and
then (140). The default formula has now been loaded and saved to memory.
To enter your own formula refer to page 10 “Entering your own formula”.
Other Formulas
To beer reect the growth stages of pastures these formulas were derived:

Seasonal variaons of formulas
1 Winter & early spring - before stem growth x125 + 640
2 Late spring & early summer - during stem growth x130 + 990
3 Mid summer x165 + 1480
4 Early autumn - before autumn rain x159 + 1180
5 Late autumn - aer rain x 157 + 970
DEXCEL also developed these month based formulas:

Some equaons may change without noce and are inuenced by
seasonal dierences. If you are unsure of the current equaon contact
your local consultant.

Entering your own formula for displaying available covers: changes
to the EC10
Displays “Available” cover required in some markets.
All the current features of the EC10 are sll there and funcon in exactly the
same way.
There is now an extra opon in the menu called “A---”
This is to allow the user to input a number that the platemeter will treat as a
negave number.
The procedure for entering a number here is done in the same way you would
enter a custom formula (same buons pressed.)
For example: if the current formula was (h x 140) + 500 and the negave num-
ber entered was 1,000, then the new formula would be: “available cover” in kg
= (h x 140) + 500 – 1000”
Where “h” equals the average height recorded by the platemeter.
Each model will leave the factory with the “A---” set at “0000”
This means that the EC10 will funcon straight out of the box exactly as they
do now and this feature will have no eect, unless acvated.
When the platemeter is switched on, it will display the default seng of:
140
500
0.0.0.0 (The decimal points will ash 3 mes indicang a negave, of any
number the user has entered and saved.)
Any changes to the formula will be retained and displayed next me the plate-
meter is switched on.
When the platemeter is used with a negave number acvated and the result
in kg of dry maer is < “0”, then the LCD will display “0000”. The platemeter
will sll beep with each plonk and connue to count. The hyphens will ash on
and o with each beep. An “Actual” negave number cannot be displayed.
A posive number result aer calculaon will sll show as a posive number
as normal.
