1Introduction
Thank you for choosing this AGRETO weighing display. You ha e just
purchased a robust appliance for e eryday use.
Please read this manual carefully before putting the weighing display to use.
As in common parlance, the word 'load' is used instead of 'mass' in this user
manual.
2Scope of delivery
The AGRETO Weighing Display HD1 consists of:
The weighing display itself
Brackets for wall and table mounting
Bracket for stand mounting
This user manual
Intended use
The AGRETO weighing indicator HD1 is suitable for all weighing applications,
where no officially calibration is needed.
It is designed for use in humid, dusty rooms. The protection class is IP67. It can
therefore also be used in stables and other humid rooms.
The display can be connected to most of the common load cells, weighing
platforms or other weighing de ices.
The AGRETO HD1 isn't officially 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 display. If you ha e one of those, you connect the cable's 7-pole
round plug to the fitting round plug coming out of the weighing display (that's
the plug without a protecti e cap).
To connect to other weighing scales you use the connection diagram as
explained by the following table:

7.1 Turning on the weighing display
Press the [ 

 ] button. The weighing display will now run a self-test. The display
is ready for use when the weight readout appears.
In standard mode the display isn't put to zero, but shows the actual load, based
on the null position that was last used.
NOTE: Calibration parameter 3 allows you to configure if and up to what load
the display automatically re erts to the zero position during start-up.
7.2 Zeroing
With the [ 

0

 ] button the display's zero position is reset. Use this function
before e ery weighing if the display isn't set to zero.
When the display is set to zero the symbol 

0

0

 will light up in the top left
corner of the display screen.
NOTE: Calibration parameter 2 allows you to configure the range for manual zero
positioning.
7. Standard weighing procedure
Make sure that the display is set to zero.
Put the weighing object on the scales.
Wait until the weighing display shows a stable alue, or until the symbol for
weight stability lights up in the top left corner of the display screen.
Read the weighing result.

7.4 Weighing with Tare function
When you'd like to weigh an object in a container or package, the weight of the
empty container can be automatically subtracted without changing the zero
position, by using the tare function.
Make sure the display is set to zero.
Put the empty container on the scales.
Wait until the display shows a stable alue, or until the symbol for weight
stability lights up in the top left corner of the display screen.
Press the [ 

T

 ] button. The display goes back to zero and the NET
symbol appears.
Now put the weighing object in the container.
Wait until the display shows a stable alue, or until the symbol for weight
stability lights up in the left top corner of the display screen.
Read the weighing result. This is the net weight of the object without
container.
If you would like to weigh se eral objects in the same container, you can put
them on the scales one after the other. As long as the NET symbol is isible,
the pre iously measured tare will be subtracted and only the net weight
shown.
To end the tare function you take the load from the scales and press the
[ 

 ] button again.
7.5 Weight summation
Do the following if you would like to perform se eral weighings and add up all
the loads:
Make sure the display is set to zero.
Put the weighing object on the scales.

Shortly press the [ ∑ ] button. The display will show the sum of the objects
weighed so far, followed by the amount of weighed objects so far (n 0001),
after which it returns to the normal weighing mode. The AUTO symbol lights
up as long as the sum and amount of weighed objects are displayed.
Remo e the first load from the scales and introduce the next load.
Shortly press the [ ∑ ] button again. Again, the display shows the sum of the
objects weighed so far, followed by 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)

7.6 Animal weighing mode
If you'd like to weigh restless animals or unstable loads, you can use the animal
weighing mode. Take the following steps:
Make sure the display is set to zero.
Put the weighing object on the scales.
If you shortly press the [ Fn ] button, the weight display will be replaced by

continuously. The result that is displayed, is the a erage of all weighings
during those 5 seconds.
The result remains displayed until you press the [ Fn ] button again, or
remo e the weighing object from the scales (and the load is lower than 5
increments).
TTENTION: The animal weighing mode will only start after a load of at least 5
increments (for instance: for scales with a 1 kg resolution the animal weighing
mode starts at a load of 5 kg).
TTENTION: If you press the [ Fn
FnFn
Fn ] button for too long, parameter configuration
will start up instead of animal weighing mode.
