8. BASIC FUNCTIONS
8.1 ZERO SCALE
By pressing the ZERO key, it is possible to zero a gross weight value which is within +/- 2% of the capacity; after the
zeroing, the display shows 0 weight and the relative pilot lights are turned on.
8.2 TARE OPERATIONS
SEMI-AUTOMATIC TARE
By pressing the TARE key any weight value present on the display is put in tare: the display shows “tArE” for an instant and
then 0 (net weight); the pilot lights turn on.
NOTE: The semiautomatic tare will be acquire only if the weight is AT LEAST A DIVISION, STABLE (instability ~ led off)
and VALID (in other words, the OVERLOAD condition must not be created).
ENTERING THE MANUAL TARE FROM KEYBOARD
Press TARE for a few seconds: the display shows “– tM –“ and then "000000". Enter the desired value using the following
keys:
ZERO
decreases the blinking digit.
TARE
increases the blinking digit.
MODE
selects the digit to be modified (blinking); the scrolling of the digits takes place from left to right.
C
if pressed for an instant it quickly zeros the present value; if pressed at length it allows to return to weighing
without saving the changes made.
Confirm with the ENTER/PRINT key; the value will be subtracted from the weight present on the plate and the relative pilot
lights will turn on.
CANCELLING A TARE
One can manually cancel the tare value in different ways:
- unload the scale and press the TARE or ZERO key.
- carry out the tares in subtraction, partially unloading the scale and, and press TARE to zero the display.
- press C without unloading the scale.
- enter a manual tare equal to 0.
NOTE: it is possible to automatically cancel the tare value; see the following section.

WWSRF platforms
WWSRF_03_11.11_EN_U
LOCKED/UNLOCKED/DISABLED TARE SELECTION
Normally, when a tare value is entered (automatic or manual) by unloading the scale plate, the display shows the tare value
with a negative sign (LOCKED TARE). For one’s convenience it is also possible to choose that the tare value cancels itself
automatically each time that the scale is unloaded (UNLOCKED TARE); or disable the tare functions.
With the UNLOCKED tare:
In case of SEMIAUTOMATIC TARE the net weight, before unloading the scale, may also be 0.
In case of MANUAL TARE the net weight before unloading the scale must be greater than 2 divisions and stable.
To set the type of tare:
- Turn on the indicator, press the TARE while the firmware version is displayed (the display shows the “tyPE” menu).
- Press ZERO many times (to scroll ahead through the parameters) or TARE (to scroll backwards) until one finds the
“F.ModE” parameter.
- Press ENTER/PRINT to enter the menu.
- Press ZERO many times (to scroll ahead through the parameters) or TARE (to scroll backwards) until one finds the “tArE”
parameter.
- With the ZERO or TARE keys select the possible options: “LoCK” (locked tare), “unLoCK” (unlocked tare), “diSAb”
(disabled tare).
