KEYBOARD & DISPLAY
LCD DISPLAY
Displays the weight on the scale pan.
In HOLD mode, the display flashes to indicate that the real weight on the scale is not being shown, with the last registered stable
weight being shown instead.
Measurement unit used to indicate the weight.
Counting mode activated: The display shows the amount of units, not de weight.
Stable weight reading: There is a weight on the platform that is not fluctuating. Flashes to indicate that there is movement on the
scale.
Negative sign.
This reading may be negative if a tare is activated or to indicate a problem when setting it to zero.
Indicates net weight. The net weight is the actual 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.
Memory preset tare. The current tare is a value recorded into the indicador’s memory, it could be not necessarily a measured
value.
Scale is set to zero (weigh is less than ¼division)
High resolution mode. Additional digit to show the weight with a resolution of 1/10 of the scale division.
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 pan and the value of
the lower limit. The thickest segment indicates that the weight is less than the value set as a lower limit in a proportion of 100% or
more.
The weight is within the range between the lower limit and the upper (high) limit.
The weight is above the upper (high) limit.
The 4 segments of this indicator are activated proportionally to the difference between the weight on the balance and the value
of the upper limit. The thickest segment indicates that the weight exceeds the value set as the upper limit in a proportion of 100%
or more.
Battery-operated. When not connected to the mains, shows the charge level of the battery.
Connected to the mains.

KEYBOARD & DISPLAY
On / Off. Press once to switch the indicator on. Hold the key down for 2 segundos to switch off the

Factory setting

At the SCAlE menu you will find the settings needed to define and adjust the measurement scale of the instrument:
Measurement unit, maximal capacity, scale interval (division), decimal point, as well as different options related to the
operation of the auto-zero device.
Access to these configuration options is reserved for technical personnel and is protected by a keyword to avoid
accidental changes that would cause the instrument to malfunction.
It is possible to directly access the adjustment (calibration) function of the instrument when the indicator is turned on.
To do this, turn on the indicator, and while the LCD test appears with all segments on, press the and keys at the
same time (one short press, not sustained).
Once you have entered the access code to the scale settings menu, with the scale empty, select the option
CALIB.
1. The display will show that the adquisition of the initial zero value is in progress with the blinking message “CAL 0”.
2.
Once the zero value has been adjusted, place the adjustment weight (a standard weight) on the load receptor.
3.
Enter the weight value in the indicator, including the decimal positions. Use the cursor movement keys to move
through the different positions on the display.
4.
Once you enter the weight value, double click the ¿key to validate and move to next step. The display will
show the blinking message “-CAL-“ while acquiring the adjustment value
5.
Lastly, it will show the message “ GEO “ for a few seconds, asking for the code of the geographical location where you
did the adjustment.
The geographical location code is a value from 0 to 31, which you have to choose from the attached table. Use the
$ and ¯ keys to change the value and validate by clicking on the ¿ key .
6.
Lastly, the message “ SAVE ” will briefly appear, indicating that the adjustment has been saved in the non-volatile
memory. The indicator returns to normal use mode, displaying the weight on the load receptor .
If the automatic correction of the weight according to the geographical latitude and height (“ G-COR option”) is set to
ON, the next time you switch on the indicator after an adjustment, once the display test and initial welcome message
is completed, the user will be asked to enter the value corresponding to the geographical area where the scale will be
used
.
Once the value has been entered for the geographical area where the scale is placed, it is recorded in the non-
volatile memory of the indicator, and the user will not be asked for it again.
The geographical area where the scale is used can be modified later whenever you wish by entering the menu with NEnU
àSCALE àCAL àG-SET àGEO àG nn (being nn {0-31}).
The automatic correction of the setting according to geographical area can be disabled by entering the menu with
NEnU
àSCALE àCAL àG-SET àG-Cor àOFF
