1. KEYPAD AND LCD DISPLAY
Switches the device On / Off.Press once to switch the scale on. Hold
the key down for 2 seconds to switch off the scale.
Esc / Menu. It enters the menu settings mode. When already into the
settings menu mode, escapes to the previous menu option or back to
the weighing mode.
High Resolution. Activates the high-resolution mode. One more digit
is added to the weight value for 4 seconds.
High / Low limits: activates / deactivates the checkweigher mode. ).
Clicking twice will access the “H/L” mode settings.
Zero button. Sets the scale to zero.
Tare . A short pulse activates the tare function. This may be
“measured tare” or “Pre-set tare” depending on the operating mode
selected in the settings menu. If there is a pre-set tare in the memory
and the platform is empty, pressing this button deactivates the tare.
When clicking twice (double click) the tare mode alternates from
“pre-set tare” to “measured tare”.

6
Left / Right arrow. Selects and edit a tare memory record.
Print / Enter. When in “Weighing mode” prints the current weighing
data (simple ticket mode). When clicking twice, starts printing a
totalisation ticket. When holding pressed for 2 seconds, ends the
current totalisation ticket. When in menu settings mode, it confirms
the selection/modification made.
Clock and Up Arrow. In weighing mode, press to show the
totalization amount. When keep pressed for 2 seconds will show the
date and time. In menu mode, when editing a value, it increases the
value (digit) of the display.
MC and Down Arrow When in weighing mode, keep pressed for 2
seconds to perform the “Clear” function: Cancel the tare, and resets
the total weight. In menu mode, when editing a value, it decreases
the value (digit) show on the display.

LCD display symbols and readings:
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.
Battery-operated. Shows the charge level of the battery when not connected to the mains,
Plugged to the mains.

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.
