INDICATOR
FUNCTION
0
Indicates that the weight detected on the weighing system is near zero.
M+
Indicates that total value is greater than 0.
NET
Indicates that the displayed weight is a net weight.
LOW-PCS
Indicates that an insufficient number of samples was used in order to determine an accurate
count (see section 5.5.3).
LOW-APW
Indicates that the
A
verage
P
iece
W
eight (
APW
) is insufficient in order to determine an
accurate count (see section 5.5.3).
5. OPERATION
5.1 AUTOMATIC ZERO UPON START-UP
The indicator has an “auto zero at start-up” function: in other words it means that if at start-up a weight /- 10%
of the capacity is detected, it will be zeroed; if the weight is not within this tolerance, the display shows “Err 2” and with
a non approved instrument the present weight after a few instants, while with an approved instrument “ZERO” is shown
continuously.
5.2 SCALE ZERO FUNCTION
When there is no item on the scale but reading is not zero, press the
ZERO
key to turn on
0
indicator. If the
weight is greater than +/- 2% in respect to the capacity, the zeroing will have no effect.
5.3 TARE FUNCTION
5.3.1 ENTRY OF SEMIAUTOMATIC TARE
Zero the scale by pressing the
ZERO
key if necessary (see section 5.2). The “
0
” symbol will be on.
Place a container on the platform, a value for its weight will be displayed.
Press the
TARE
key to tare the scale once the weight reading is stable. The weight that was displayed is stored as the
tare value and that value is subtracted from the display, leaving zero on the display. The "NET" indicator will be on. As
product is added only the weight of the product will be shown. The scale could be tared a second time if another type
of product was to be added to the first one. Again only the weight that is added after taring will be displayed.
When the container is removed a negative value will be shown.
To remove the tare, unload the scale and press again
TARE.
5.3.2 ENTRY OF PREDETERMINED MANUAL TARE
The operation can be made with unloaded platform and with no active Tare.
If a tare is
active, it is first required to unload the scale and press
TARE
to remove it.
Set the decimals’ number of the weight to introduce by pressing
C-ON/OFF
key to clear the value on the
APW
display
and by pressing 0 key several time to select the available decimals’ number: 0.0000, 0.000, 0.00.
To enter
the tare value, type the value with the keyboard; to change the entered value, one should first press the key
C-ON/OFF
key, then input the new number. If one has not input the number for 3 seconds, one can input the new
number directly without pressing the key
C-ON/OFF
key.
Press the
TARE
key to confirm the entered tare value.
The indicator automatically subtracts the entered value from the displayed weight (the
NET
symbol turns on)
as long
as the value is not greater than the maximum capacity of the instrument.
To remove the tare, unload the scale and press again
TARE.
5.4 OVERLOAD MESSAGE
Please do not add item that is over the maximum capacity. When reading “- - - - -” and hear beeping sound, remove
the item on the platter to avoid damage to the load cell.
