Displays the weight on the scale platform.
Unit of measurement in which the weight is indicated.
Stable weight reading: There is a weight on the platform that is not fluctuating.
Intermittent or switched off to indicate that there is movement in the scale.
Negative sign.
Weight value may be negative if a tare is activated (when pre-set tare mode).
Indicates net weight. The net weight is the real weight on the scale minus the tare. It is only
displayed if a tare has been used.
Tare activated.
The reading flashes when “normal” tare mode has been activated.
A “pre-set” tare is retained even after the weight is removed from the scale platform.
Memory pre-set tare. The current tare is a value recorded into the indicator’s memory; it could
be not necessarily a measured value.
Scale is set to zero (weigh is less than ¼ division)
Reading in high-resolution mode. It shows a division 10 times smaller than the one defined in the
weighing scale range.
Double range mode, when using the scale range 1.
Double range mode, when using the scale range 2.
The weight is below the lower limit.
The 4 segments of this indicator are activated proportionally to the difference between the
weight on the scale and the value of the lower limit. The thickest segment indicates that the
weight is lower than the value set as the lower limit in a proportion of 100% or more.
The weight is within the interval encompassed between the lower limit and the upper (high) limit.
The weight is above the upper limit.
The 4 segments of this indicator are activated proportionally to the difference between the
weight on the scale and the value of the upper limit. The thickest segment indicates that the
weight is higher than the value set as the upper limit in a proportion of 100% or more.

2. BEFORE USING THE SCALE
1. AC/DC adapter, output 12 Vdc –1 A
2. Space allocated for additional options.
3. RS-232 data output.
4. Connector for the XTREM platform.
Attach the AC/DC power source to the unit and to a mains power outlet for
charging the battery before its first use.
Attach the Xtrem platform cable to the Xtrem connector of the K3Xterminal.

9
The load receptor platform should be placed on a flat surface free of any
irregularities.
For the proper functioning of the instrument, the platform should be
horizontally levelled. Before using the scale, check the bubble level mounted
on the platform structure and adjust the levelling feet if necessary.
Both Xtrem module and the weight sensors mounted on the platform are
sensitive to changes in ambient temperature. To achieve maximum accuracy,
we recommend you keep the scale switched on for at least 30 minutes in its
set-up site before using it.

3. ON / OFF
Press on the key. The display switches on and performs the
following sequence:
1. All segments and symbols switch on for a second on the LCD display to
verify that they are functioning properly.
2. It then shows the unit’s firmware version code during one second.
3. Whilst connecting to the Xtrem scale will show a scrolling “-“sign.
4. Finally, will show the message whilst performing the initial zero
setting of the scale.
After the power-up sequence the scale is ready for use.
To switch off the unit, press on the same power-on key and keep it pressed
for 2 seconds. An message will appear to warn that the device will be
switched off when the key is released.
4. INITIAL ZERO SETTING
When switching on the unit, it will automatically set to zero. This will be
indicated in the display with the message .
Automatically resetting to zero at the start requires the scale to remain
stable for at least 5 seconds. For as long as the scale is moving, the
indication will be maintained for a maximum of 10 seconds.
If this time is exceeded without obtaining a stable reading, the display will
show the weight on the scale.
If the weight on the load receptor is higher than 10% of the scale’s maximum
capacity, the scale will not set to zero, and the display will show the weight
on the scale.
The option in the configuration menu allows to activate or
deactivates the initial zeroing as well as change the initial zero setting range.

6. OPERATION
6.1. USE OF THE SCALE
Once the unit is switched on, the weight display will indicate that the scale:
•is set to zero, meaning that there is no load placed on the platform.
•the reading is stable, that is to say, there is no external influencing
factor (such as an air current or the vibration of a nearby engine) that
may be producing significant disruption.
To find out the weight of any object within the scale’s maximum range, place
it on the load receptor platform: The zero reading and the stability reading
disappears from the indicator; the weight value will change until the stability
reading becomes visible again. The value indicated in the display is the result
of the measurement.

13
6.2. TARE FUNCTION
A short press on this key activates the tare function: The scale
memorizes the weight currently on the load receptor and
subtracts it from the total weight until the tare function is
deactivated or cancelled.
The tare function only operates if the weight is stable. If the stability indicator
is switched off, pressing this key has no effect.
Tare function can only be done when there is a weight higher than zero on
the scale.
It can be “Normal measured Tare” or “Pre-set Tare” depending on the
operating mode selected in the configuration menu (see option ).
•Pre-set tare. The tare remains after unload the load receptor. The >T<
indication on the display stays constant, non-flashing. When the scale is
emptied, the display shows the tare value with a negative sign. To cancel
the tare, press on the tare button again after unloading the load
receptor.
•Normal measured tare. The tare is automatically deactivated when the
load receptor is empty. The >T< indicator is switched on intermittently in
the LCD display.
Double press this key to switch the operating mode from “pre-set tare” to
“normal measured tare”. The default operating mode for tare is “pre-set
tare”, although this setting can be changed in the options menu (see option
).
To cancel the tare when a “pre-set”tare is active, with the load receptor
empty, press the tare button again. The “clear” function (keep the MC button
pressed for more than one second) also deactivates the tare. The zero-setting
key also deactivates the tare.

14
6.3. MEMORY TARE RECORDING
It is possible to apply a tare previously memorized in the equipment. The
indicator has up to 20 tare records, numbered from 1 to 20.
Use the and →keys to access this register and select one of the stored
tares.
The display will show the message ; press the →key to move on to
register and so on. Pressing the key returns to the previous tare
memory.
Once you have selected the tare memory you wish to use, press the ,key,
the display will show the associated tare value. Press and hold pressed the 
key for more than 1 second to apply the tare and the display returns to
weight display mode.
To change the value associated with a tare value, follow the procedure
below:
1. Use the y →keys to select the tare value you wish to modify and
press the key.
2. The display shows the tare value associated with the selected register.
3. Enter the desired value using the arrow keys →to move to the next
digit and the keys ↑↓para to modify the value of each digit.
4. Hold pressed the key for more than 1 second to validate the display
content and store it in the indicator memory.
When a memorized tare is used, the display shows the (“preset tare”)
reading.
To cancel the tare, with the scale empty, press the tare button again. The
"clear" function (press and hold the MC button) also disables the tare. The
zero-setting key also disables the tare.

15
6.4. ZERO SETTING
A short press on this key sets the scale to zero. The scale is
deemed to be “set to zero” when the weight on the load receptor
is lower than ¼ of division.
While the scale is “set to zero”, the reading is shown in the display.
When the scale is set to zero the automatic “zero tracking” device is in
operation. This function automatically sets to zero when variations of less
than ¼ division occur if they do not add up to more than ¼ division during
one second. This function can be deactivated in the option of the
configuration menu.
Pressing on the zero key also deactivates the tare if it happens to be
activated.
The zeroing of the scale is limited to 4% of its maximum capacity. Pressing
the zero-setting button will not take effect when this margin is exceeded.
6.5. HIGH-RESOLUTION MODE
When pressing HR key, the scale’s resolution is enlarged by x10,
allowing the weight to be viewed with a 10-times-smaller division
for 4 seconds.
An additional digit appears in the weight display, and the decimal point is
shifted to the left by one position. This additional digit is indicated with a
straight angle in its top left corner:
1 Example for a scale with a 1-kg division in normal mode and in high-resolution mode

16
6.6. H-L MODE (CONTROL OF UPPER/LOWER LIMITS)
Activates or deactivates the upper and lower limit control mode.
For an instant, the display shows the message to indicate
that it has been activated, or the message to indicate
that it has been deactivated.
When the limit control is activated, a reading lights up in the bottom part of
the LCD display to signal whether the net weight on the plate is lower than
the value or higher than the value. When the weight lies between
the two values, a sign appears indicating that the weight is in the interval
defined by the lower limit and the upper limit.
The colour of the display’s backlighting changes to red when the weight is
outside the interval defined by the upper and lower limit, and changes to
green when the weight is within said interval.
The 4 segments of this reading are activated proportionally to the difference
between the net weight on the scale and the value of the lower or upper
limit. The thicker segment indicates that the weight is below the value set as
the limit in a proportion of 100% or more.
Double-press on the H-L key to access the configuration and change the
lower and upper limits. The possible options are:
Value for the lower limit, including the decimal part.
Value for the upper limit, including the decimal part.
Yes / No: Activating the limit control when switching on
the unit.

17
6.7. DOSING MODE
The dosing mode is activated and configured by accessing the options menu
in the section (see section 16 in this manual).
Pressing the tare key initiates the dosing cycle, closing the K1 and
K3 relay contacts. The display changes to blue to indicate that the
dosing cycle has been initiated.
Upon reaching the weight established for (coarse flow), contact K1
is opened, and the display colour changes to indicate that the fine flow is in
operation.
Upon reaching the weight set point established for (fine flow),
contact K3 is opened and contact K2 is closed to indicate that the dosing
cycle has finished. The light of the LCD display changes to green to indicate
that the dosing cycle has finished.
Relay K2 (signalling the end of the dosing cycle) stays closed until the weight
is removed from the scale. It is not possible to initiate a new dosing cycle if
the cycle end outlet (K2 relay contact) stays closed.
To stop and pause a dosing cycle being run, press on the “tare” key. This
action will open the K1 and K3 relay contacts, halting the dosing until the tare
key is pressed again.
To stop and cancel a dosing cycle being run, hold pressed for 2 seconds the
MC key .

18
6.8. PRINTING A SINGLE WEIGHING TICKET
Pressing this key when in “weighing mode”, will print the
current weighing information (single weighing ticket).
The print key will only be effective if the weight on the scale is stable (the
stability indicator is switched on).
A short press on this key will print a ticket with the following information:
date and time, the Xtrem scale identification, the ticket’s serial number, gross
weight, tare, and net weight (just the weight when not using the tare
function).
1 Weighing ticket in “weighing mode”
Additionally, you can print a 3-line header and a footer line with constant
information.
This gross/tare/net ticket is only possible provided no totalisation ticket has
been initiated, which has a different format.

19
6.9. PRINTING A TOTALIZER TICKET
Double press the print key will starts printing a totalizer ticket.
When holding pressed for 2 seconds, prints the current total and
exits the totalizer function.
The print key will only be effective if the weight on the scale is stable (the
stability indicator is on).
To initiate a totalizer ticket, weigh the first object to be added to the total
and double press the print key. The weight is printed and added to the
accumulated total. Repeat this operation to aggregate and print each one of
the subsequent weights to the ticket.
At the end of each weighing sum, the total accumulated sum appears in the
display for 2 seconds.
To complete the ticket and print the line for the total, press and hold pressed
for 2 seconds the print key. You can view the total at any time before
completing the ticket by pressing on the key.
