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
AUTOMATIC TARE
By loading any weight on the scale, the corresponding value is acquired as tare.
NOTE:
The automatic tare will be acquired 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).
SEMI-AUTOMATIC TARE
By pressing the
TARE
key any weight value present on the display is tared: the display shows “tArE” for an instant and then
0 (net weight); the pilot lights turn on.
NOTE:
The semiautomatic tare will be acquired 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.
M+
selects the digit to be modified (blinking); the scrolling of the digits takes place from left to right.
MODE/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
MR
key; the value will be subtracted from the weight present on the plate and the relative pilot lights will
turn on.
NOTE:
If the entered value is not a multiple of the scale’s minimum division, it will be rounded off.
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 deduction, partially unloading the scale and pressing
TARE
to zero the display.
- enter a manual tare equal to 0.
NOTE: it is possible to automatically cancel the tare value; see the following section.
LOCKED/UNLOCKED/AUTO/DISABLED TARE SELECTION
Normally, when a tare value is entered (semi-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 AUTO 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 scale, press the TARE while the firmware version is displayed (the display shows the “F.ModE” menu).
-
Press MR 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.
-
Press MR to enter the parameter.
-
With the ZERO or TARE keys select the possible options: “LoCK” (locked tare), “unLoCK” (unlocked tare), “Auto”
(automatic tare), “diSAb” (disabled tare).
-
Confirm with MR.
