1. KEYPAD AND LCD DISPLAY
Switches the unit On / Off.Pressing it lights up the indicator. With
the indicator on, keeping it pressed for two seconds switches it off.
Piece counter mode. Activates or deactivates the piece counter
mode. Double-pressing it gives access to the options menu of the
piece counter mode. In menu mode you have the function of exiting
the menu and returning to normal mode (Escape).
Gross/Net. When the tare is used, when pressed it shows the gross
weight (total weight on the scale) and when pressed again it shows
the net weight. Keeping it pressed for more than one second
automatically selects the “Weight Limit” mode. Double-pressing it
gives access to the limits configuration menu.
PLU - product code. Pressing it gives access to the product code
memory (PLU). Keeping it pressed for more than one second leads to
the scale configuration and settings menu. Double-pressing it
activates or deactivates the HOLD mode.
Zero / Test / High-resolution. Zeroing the scale. Pressing it for more
than one second shows the display test, capacity, division and

6
software version. Double-pressing the key activates the high-
resolution mode. When editing the value of an alphanumerical data,
it switches between upper case, lower case and numbers / symbols.
Tare. Pressing it once subtracts the weight of any receptacle or box
placed on the platform until the weight is removed from the platform
and this key is pressed again. Keeping it pressed switches between
“fixed tare” and “normal tare” mode. Double-pressing it gives access
to the tare memory, for selecting a record or editing the associated
tare value.
M+ and right arrow. When pressed, it adds the weight indicated in
the display to the total, initiates the accumulated ticket if it was not
yet initiated and sends the ticket data to the printer. In addition, for a
few moments it shows the accumulated total. In menu mode it
displays the next option.
MR and left arrow. When pressing on it on the main screen, it closes
and sends the totalizer ticket data and shows the accumulated weight
total. In menu mode it returns to the previous menu.
Enter. When pressing on it on the main screen, it sends the current
weight data to the printer (single ticket). Keeping it pressed for two
seconds activates the blocking/unblocking of the keypad. In menu
mode it confirms the selection/modification made.
Clock and Up Arrow. A short press displays the accumulated value in
the total. Pressing it for more than a second displays the date and
time. In menu mode, when editing the content of a parameter, it
increases the value (digit) of the display.
MC and Down Arrow. In menu mode, when editing a parameter, the
value (digit) shown in the display decreases. If kept pressed for more
than one second, it runs the “Clear” function: It voids the tare,
cancels the “hold” mode and resets the accumulated weight total.

7
Displays the weight on the scale platform.
In HOLD mode, the reading is shown intermittently to signal that it is not indicating the real weight on the scale but the latest
stable weight recorded.
Unit of measurement in which the weight is indicated.
Piece counter mode: The display shows the number of units, not the weight.
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.
This reading may be negative if a tare is activated (in preset tare mode) or to indicate a problem when setting it to zero.
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 “preset” tare is retained even after the weight is removed from the scale platform.
Tare in memory. The tare being subtracted from the weight is a value recorded in the indicator memory, not necessarily a
measured value.
Scale set to zero: The weight on the load receptor is lower than ¼ interval (division).
Reading in high-resolution mode. It shows a division 10 times smaller than the one defined in the weighing scale range.
In double range mode, it indicates that the scale’s range 1 is being used.
In double range mode, it indicates that the scale’s range 2 is being used.
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 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. Not connected to the mains. The load level is indicated.
AC/DC supply connected to the power outlet.

2. BEFORE USING THE SCALE
1. AC/DC adapter, output 12 Vdc –1 A
2. Space allocated for optional enlargements
3. Connector for the C1 load receptor platform
4. RS-232 data output
5. Connector for the XTREM platform
Connect the AC/DC power source to the unit and to a power outlet suitable
for charging the battery before its first use.
Connect the load receptor platform cable in the C1 connector of the K3
indicator.

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 included
in the actual platform and adjust the levelling feet if necessary.
Both the K3 indicator and the weight sensors included in the platform are
sensitive to changes in ambient temperature. To achieve maximum precision,
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. Finally, for one second it displays the scale’s maximum capacity and
the interval.
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 RESET TO ZERO
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 period is exceeded without obtaining a stable reading, the display
will show an message followed by the weight on the scale.
If the weight on the load receptor is higher than 10% of the scale’s maximum
capacity, the error message will be displayed, followed by the weight
on the scale.
The option in the configuration menu activates or deactivates the
initial zeroing.
