1Introduction
Thank ou for choosing this AGRETO weighing displa . You have just
purchased a robust appliance for ever da use.
Please read this manual carefull before putting the weighing displa to use.
As in common parlance, the word 'load' is used instead of 'mass' in this user
manual.
Scope of delivery
The AGRETO Weighing Displa HD1 consists of:
The weighing displa itself
Brackets for wall and table mounting
This user manual
3Intended use
The AGRETO weighing indicator XK3 is intended to be use in dr locations. The
protection class is IP63.
The displa can be connected to most of the common load cells, weighing
platforms or other weighing devices.
The AGRETO XK3 isn't officiall calibratable and therefore not authorized to
determine weights for legal transactions.

6.1 Connecting the load cells
AGRETO weighing scales are supplied with a connection cable that fits in the
weighing displa . In this case, connect the 9-pin D-SUB connector of the cradle
cable to the matching port on the back of the weighing indicator.
To connect to other weighing scales ou use the connection diagram as
explained b the following table:

6. Connecting the power supply
Connect the small round plug of the power cord into the socket provided on the
back of the displa and plug the power adapter into the power outlet.
The displa can also be used with the built-in batter . Charge the batter
completel before the first use definitel on.
7Weighing
7.1 Turning on the weighing display
Press the [ 

 ] button. The weighing displa will now run a self-test. The displa
is read for use when the weight readout appears.
In standard mode the displa isn't put to zero, but shows the actual load, based
on the null position that was last used.
NOTE: Calibration parameter 3 allows ou to configure if and up to what load
the displa automaticall reverts to the zero position during start-up.
7. Zeroing
With the [ 

0
00
0

 ] button the displa 's zero position is reset. Use this function
before ever weighing if the displa isn't set to zero.
If the displa is zero the LED (Zero) lights.
NOTE: Calibration parameter 2 allows you to configure the range for manual zero
positioning.
7.3 Standard weighing procedure
Make sure that the displa is set to zero.
Put the weighing object on the scale.
Wait until the displa shows a stable value or until the LED () lights.
Read the weighing result.

7.4 Weighing with Tare function
When ou'd like to weigh an object in a container or package, the weight of the
empt container can be automaticall subtracted without changing the zero
position, b using the tare function.
Make sure the displa is set to zero.
Put the empt container on the scales.
Wait until the displa shows a stable value, or until the LED () lights.
Press the [ Tare ] button. The displa goes back to zero and the LED (Net)
lights.
Now put the weighing object in the container.
Wait until the displa shows a stable value and until the LED () lights.
Read the weighing result. This is the net weight of the object without
container.
If ou would like to weigh several objects in the same container, ou can
put them on the scales one after the other. As long as the NET – LED ist
lighting, the previousl measured tare will be subtracted and onl the net
weight shown.
To end the tare function ou take the load from the scales and press the [
Tare ] button again.
7.5 Weight summation
Do the following if ou would like to perform several weighings and add up all
the loads:
Make sure the displa is set to zero.
Put the weighing object on the scales.
Waid until the displa shows a stable value and the LED () lights.
Read the weighing result.
Shortl press the [ ∑ ] button. The displa will show the sum of the objects
weighed so far, followed b the amount of weighed objects so far (n 0001),
after which it returns to the normal weighing mode. The LED ( ∑ ) lights up
as long as the sum and amount of weighed objects are displa ed.
Remove the first load from the scales and introduce the next load.

Shortl press the [ ∑ ] button again. Again, the displa shows the sum of
the objects weighed so far, followed b the amount of weighed objects so
far (n 0002) after which it returns to the normal weighing mode.
Repeat this procedure with all weighing objects.
TTENTION: The summation function will only start after a load of at least 5
increments (for instance: for scales with a 1 kg resolution the summation
function starts at a load of 5 kg)

Displa ing the sum
To displa the sum of weighed loads permanentl press the [Σ] ke and keep it
pressed until a beep sounds. If ou release the button the sum of the weights is
displa ed and the two LEDs (Fn) and (Σ) light.
While the sum is displa ed, ou can use the [ 

normal weighing mode. The sum remains stored, so ou can add additional
weighings.

Press the [Σ] ke and keep it pressed until a beep sounds. If ou release
the button the sum of the weights is displa ed and the two LEDs (Fn) and
(Σ) light (as above).
Press the button [  ], the displa shows „CLEAR“.
Press the [  ] button to confirm the deletion. The sum and amount are set
to 0 again, and the displa reverts to the normal weighing mode
Press the [ Fn ] button to cancel the deletion.

7.6 Animal weighing mode
If ou'd like to weigh restless animals or unstable loads, ou can use the animal
weighing mode. Take the following steps:
Press the [ Fn
FnFn
Fn ] ke shortl to activate animal weighing mode. The displa
shows “ON” for a short time.
Make sure that the displa is set to zero.
Put the weighing object on the scale.
If the weight is in the range r for the time t the average of this time is
calculated, shown and freezed on the displa until the weight is out of the
range. The red point above the “Fn” is illuminated.
Example: Put an animale on the scale, the weight is going up and down. If
the weight is in a range of 20 kg for 3 seconds, the average weight of this 3
seconds is calculated and displa ed. Now ou can take the weight. When
the animal goes awa from the scale the range is exceeded and the scale
is showing the actual weight again.
The parameters r (range) and t (time) can be adjusted.
To turn off the animal weighing mode press the [ Fn
FnFn
Fn ] ke shortl . The
displa shows “OFF” for a short time.
C UTION: The animal weighing mode is only working if the [ Fn
FnFn
Fn ] key is
assigned with the function NL.
C UTION: The animal weighing mode is started only if the weight is above the
minimal weight which is set in the parameter LO.
C UTION: If you press the [ Fn
FnFn
Fn ] button too long, parameter configuration will
start up instead of animal weighing mode.

The Weighing Displa HD1 has several configurable parameters that influence
the wa the s stem functions. Normall these parameters have been pre-
configured correctl and need onl be altered in special circumstances.
Take the following steps to start parameter configuration:
To enter the parameter menu press and hold down the [Fn] ke until a
signal sounds
Pressing the [  ] button confirms the entr and returns to the next
parameter. After the last parameter the parameter menu is closed and the
displa returns again in weighing mode.
The [  ] button allows ou to select the desired parameter value.

9Calibration
If ou bought the weighing displa together with AGRETO weighing scales, the
displa is alread full calibrated and checked.
Calibration is onl needed:
If ou didn't bu the weighing displa together with AGRETO weighing
scales.
If ou use the scales for a special construction, for example when ou want
to retrofit mechanical scales.
If the location of the weighing s stem is outside of the geographical area
between 45 and 52 degrees latitude.
If the location of the weighing s stem is at an altitude higher than 1000 m
above sea level.
If for whatever reason ou do not succeed in using the scales in the
prescribed mounting position.

cannot be undone!cannot be undone!
cannot be undone!
To perform a calibration ou need a reference load that is as close as possible
to the nominal load. It should be at least 20% of the nominal load of the load
cells. This means that scales with a nominal load of 4000 kg need to be
calibrated with at least 800 kg.
Take the following steps to start the calibration procedure:
For entr into the calibration, remove the protective cover on the back and
press the inner button until the displa shows the word CAL.
Pressing the button [  ] confirms the entr and returns to the next
parameter. After the last parameter the parameter menu is closed and the
displa returns into weighing mode
Press the [  ] the desired value or the desired setting can be selected
within a parameter.
The [  ] button allows ou to switch between digits for multi-digit entries
All the steps of the calibration process are described in the following table.
The must be performed in this order.
