2 – GENERAL FUNCTIONS
2.1 – Auto-tare
The Auto-tare function permits to cancel the weight of an empty connector placed on the plate
of the scale.
By pressing the key TARE/2 the weight screen resets and the signal led “NET” turns on.
From this moment, each value shown on the screen has to be meant as Net Weight.
The auto-tare operation can be done more than one time and the maximum value that can be
reached while resetting corresponds to the Full-Scale deflection.
If you unload the scale, if the tare is blocked, a negative value is shown; whereas, if the tare
hasn’t been blocked, it is cancelled and the screen shows the zero scale.
2.2 – Numerical Tare
The Numerical Tare function, instead, permits to cancel a known tare value; thus, it is possible
to extract the tare from a full container placed on the scale. Thus, it is possible to see the Net
Weight in the container.
Press the key SET TARE / 3 and key the desiderd numerical value of the tare; confirm
through the key ENTER.
The keyed value is automatically rounded up to the division unity currently active.
If you insert a value that is superior than the Full-Scale, the value is refused.
2.3 – Cancellation of a tare value
In order to cancel the memorized tare, press the key SET TARE / 3 for 3 sec.
The Gross is shown once again and the signal led of the net weight turns off, in order to
confirm that the memorized tare has actually been cancelled.
2.4 – Visualization in High Res mode
This function allows to visualize the current weight in a 10 times higher resolution.
This visualization mode can be activated pressing the key SCALE / 7; the last digit flashes, in
order to highlight that the display is in High Res mode.
It is possible to go back to the standard visualization mode, pressing the key SCALE / 7 once
more.
2.5 – Set-point values setting
If the optional card relè has been installed, the device LA715 allows to manage due
interruption values that can be programmed. These values are associated with 2 relè.
It is possible to connect engines or charging valves with the relè, in order to manage a small
dosage. (The card implies the suppression of a serial port).
It is, then, possible to access the phase for the programming of the interruption values
described before, pressing the key TARGET / 8.
Thus, the display shows SETP 1; make the keyboard slide in order to move to the following
relè.
Press ENTER in order to confirm the relè.
In order to modify the desired intervention value of the relè, key the desired value and confirm
through ENTER (a briefly prolonged pressure of the key EXIT cancels the value)
Prolonging the pressure of the key EXIT for some time, it is possible to exit from the relè
setting phase.

pressing the key PRINT.
If a printer is connected, a receipt is produced.
100 weights maximum; after that the partial is printed.
3.2 – Partial Total Printing / Multiple receipt closure
it is possible to print the partial total (and related resetting) pressing the key PRINT for 3
sec.. If the multiple printing is active, the receipt gets closed.
3.3 – Receipt reprinting
It is possible to reprint a receipt, that has already been printed, pressing the key ENTER for 3
sec..
3.4 – Partial Total Visualization
After a sequence of weight, the user can ask for the visualization of the Partial total, which is
to say the sum of the weights that have been done till that moment.
If the key TOT is kept pressed, the screen alternatively shows the value of the total that has
been memorized together with ”T PAR”.

it is possible to program the best switch off / stand by mode, in order to guarantee the higher
autonomy possible.
In order to safeguard switching off option for the automatical sqitching off of the scale, after a
period of inactivity.
The possible choices are:
<RISPAR> within which it is possible to choose among:
<NESSUNO> Automatical squitching off off
<A-OFF> Automatical switching off after x minutes of inactivity
<STANDB> The standby function allows to save the charge of the battery, without
completely turning off the indicator. After x minutes of inactivity of the
scale, the screen only shows some central flashing lines. Any pressure on
the plate of the scale permits to go back to the usual funcioning..
<TIMER> It permits to set the number of minutes of inactivity

Set through keyboard the weight that is meant to be used, load the scale and confirm through ENTER.
The display shows the number of the points read by the loading cell, “FATTO”.
At the end of the sequence, the acronym “CAL” is shown again.
5.3 FILTRO : Digital filter
This parameter adjusts the digital filter that intervene on the oscillation of the visualization of the weight:
the lower the selected value, the faster the oscillation of the weight o the screen; instead, the higher the
value, the lower the updating speed of the weight on the screen, which is less sensitive to the scillations
of the plate of the scale.
Admitted values : from 0 to 9
5.4 STABIL : Digital filter on the indication of stability
The stability is indicated to the user through the apposite led on the front panel. As each operation,
printing or data transmission, is done only when the weight is stable, through this parameter it is possible
to modify the intervention sensitivity. In this case, the indicated values correspond to oscillation divisions
admitted by the system in order to consider the weight stable. The higher the number of divisions, the
lower the sensitivity. Then, the stability is more easily signalled.
