To finish, after confirming the last tare saved, display will show “ILUPro”.
Press “U/ESCAPE” to escape to weighting mode.
TARE memory use
In weighting mode, with empty platter, press “TARE”longer than a second
till “TLU XX” is shown, where XX is the last digit of the TARE memory saved.
To access another memory position, press “UP ARROW”and “DOWN
ARROW” to surf along the tare memories until you find the desired memory
number.
To confirm, press “ENTER”. Display will show tare memory value with
negative sign. Now you can place the object on the platter, and the tare
value will be deducted from weighting value (shows net weight).
You can operate with the object on the platter, then display indicate net
weighting value.
7.3 Auto Tare

Operation Manual Page 11
This function allows tare function with recipient or box to be done
automatically, without pressing “TARE” button. Display detects the first
weight (recipient or box), then operates tare function (sets to 0), and gets
ready to weight the product in the box or recipient. Afterwards, it sets to 0
and you can start again the same procedure repeatedly without pressing
any button.
Function activation
To enable Auto Tare, follow this instructions:
1. Press “PLU”. Display will show “PLUPro”. Press “RIGHT ARROW”

If there is any object on the platter, display will show the object weight,
except in the case its weight is very low, then scale will display zero.
Press “U” to select desired weighting unit (default unit is “g or kg”,
depending on its configuration).
Place the object you desire to weight on the platter. Screen will indicate
object weight value, it should be read when “stable” symbol is shown at the
top left side on the display.
7.5 Accumulative weighting
This function adds up all weighting values accumulated, and shows its total
value.
To use it, place the object you desire to weight on the platter. When display
show stabilized weight value (stable symbol on), press “RIGHT ARROW”.
Then, weight value adds to total.

Operation Manual Page 13
Repeat procedure for every object to add to the total.
To know accumulated sum value, press “LEFT ARROW” and display will
show total accumulated value.
To erase memory, press “DOWN ARROW” and accumulated value will be
deleted.
7.6 Piece counting function
The use of this mode is to count pieces of homogeneous weight. After
doing a simple sampling, scale saves the piece weight, and indicate the
number of pieces placed on the platter.
Sampling
To do the sampling, when scale shows 0 and platter is empty, press and
hold for longer than one second the “U” button until display shows “10” or
other flashing value..
This value is the quantity of pieces you can place on the platter as sampling.

Operation Manual Page 14
If pieces are small, to increase the precision of counting it is recommended
to place a number larger than 10. To do it, press “UP ARROW”, then
increase the sampling value to 20, 30, 50 or 100. To decrease, press
“DOWN ARROW”.
RTEMEMBER THAT TLE GREATER THE SAMPLE QUANTITY, THE
MORE THE MORE YOU ELIMINATE THE CHANCES OF ERROR.
Once desired value is selected, count the number of pieces indicated on the
display, place them on the platter and press “ENTER”. Display will stop
flashing and will show sampling value.
Counting
Place the pieces you desire to count (it should be the same unitary weight
from the sampling) on the weighting platter. It can be counted inside a
recipient, if tare has been done before (check Tare Use chapter)
Display will show the total quantity of pieces.
To return to Weight mode in the standard weight unit, press “U”.
If you desire to return to piece counting mode using the same unitary weight
than last time, press “U” several times still display shows “PCS” symbol.
