1.KEYBOARD AND LED INDICATORS
The frontal panel has a red led display with digit h. 20 mm and 4 led indicators and a touch
keyboard with 12 keys.
1.1 Led Indicators
If led is on, the weight is between –1/4 ÷ +1/4 of zero
If led is off , the weight is steady
If led is on , the SW21 is working with internal battery; if led is blinking, the battery
is low and need to be recharged through the charger
If led n° 1 is on , the scale is in the first weighing range
If led n° 2 is on , the scale is in the second weighing range
If both of them are on , the scale is in the third weighing range

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.

3 – FUNCTIONING MODE
3.1 – Weight with enabled totalization
If the users enables the totalization (menu SYSTEM -> TOTAL -> AB-TOT), it is possible to
weigh consecutively and to progressively add up the values of each one.
The weight placed on the scale is added up to the total actually present in memory, by
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”.
4 USER MENU ( USER )
Is is possible to access the menu voices through the prolonged pressure of the key MENU.
4.1 CLOCK: Date and Time Setting
The device LA715 has a calendar clock that automatically increases even without
external power source.
In this phase, it is possible to modify the current date and time.
It is possible to access the indicated menu through the key ENTER.
Press ENTER or DATE in order to modify the date, otherwise, press TIME to modify the time.
The device shows the memorized value as day/month/year and hour/minute.
Press ENTER to confirm the shown data or digit a new one, confirming then through ENTER.
4.2 ECONOM: Energy saving Mode setting
As the device LA715 can optionally be endued with an internal rechargeable battery, in this phase,
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
