COUNTING PIECES FUNCTION
Introduction of unit weight directly through the keyboard.
1. In weighing mode, use the numerical and decimal key to input the unit
weight. (Unit weight in grams)

2. Press the the unit weight will change.
3. If the key is not pressed in 4 seconds, the entered value will be
deleted.
Sampling introduction through number of pieces – Method 1
1. Place a number of pieces on the weighing pan.
2. In weighing mode, use the numerical and decimal keys to input the
number of pieces placed on the pan.
3. Press the key to calculate the unit weight of each piece.
4. If the key is not pressed in 4 seconds, the entered value will be
deleted.
Sampling introduction through number of pieces – Method 2
1. Be sure that the weighing pan is empty and the unit weight display is at
zero.
2. Press the key, the second display will show and the
third will show by default as 100.
3. Use the numerical and decimal keys to input the quantity of pieces.
4. Place the pieces on the weighing pan. The unit weight will be
automatically calculated.
Note: If the scale is connected to an auxiliary platform (B) and the
weighing mode is in B position (auxiliary platform) ), after pressing the
key, the input sampling will continue automatically in mode A
(scale)
Sampling introduction through number of pieces – Method 3
1. Be sure that weighing pan is empty and unit weight display is at zero.
2. Place a number of pieces on the weighing pan.
5. Press the key, the second display will show and the third
the value for default as 100.
3. Use the numerical keys to input the quantity.

4. Remove the pieces from the weighing pan. The unit weight will be
automatically calculated.
Note: If the scale is connected to an auxiliary platform (B) and the
weighing mode is in B position (auxiliary platform) ), after pressing the
key, the input sampling will continue automatically in mode A
(scale)
Sampling introduction through number of pieces – Method 4
If the unit weight is not deleted, add or remove pieces and press the
key to calculate again the unit weight.
Auto-sampling operation.
After the sampling introduction, the scale will automatically do the sampling in
mode A (scale) of any small item. Placing a new object on the weighing pan,
the scale will automatically do the sampling.
The auto-sampling function can be disabled in configuration menu CAL 1
PLU´S OPERATION
PLU Data setting
Configuration of direct PLU (keys 1 ~24)
1. Input the unit weight of the piece (see sampling introduction section)
2. Press the PLU key , the display will flash the message
3. Select the desired PLU key (1 – 24)

4. Press the PLU key to confirm and save. The message will stop
flashing.
Example
To input the unit weight of a piece of 0.5 g: Press:
1. Press the PLU key, the message will flash.
2. Press the desired PLU key, for example: , the PLU indicator will
show 3 then the symbol will flash.
3. Press again the key, the PLU indicator will show 15 then the
symbol will flash.
4. Press the PLU key to confirm, after a bip the unit weight for PLU 15 will
be of 0.5 g.
Configuration of indirect PLU´s ( 0 ~ 999 )
1. Input the unit weight of the piece (see sampling introduction section)
2. Press the PLU key, the display will show the flashing
message.
3. Use the numerical keys to select the desired PLU number.
4. Press the PLU key to confirm and save. The message will
stop flashing.
l If any data is entered in 30 seconds, the scale will automatically exit of
configuration mode and will return to normal weighing mode.

Recall of PLUs
Recall of a direct PLUs (keys 1 – 24)
l In normal weighing mode, press PLU key once (1 – 24) to access PLU
(bottom key)
l Press again the same PLU key to access to PLU (top key)
Example:
1. Press once the key, the PLU number 3 will be automatically
recalled. The display will show 3 below .
2. Press the same key again. The PLU number 15 will be
automatically recalled. The display will show 15 below .
Recall of an indirect PLU (0 – 999)
1. In normal weighing mode, keep pressed the PLU until the scale gives
a double beep, then release the key.
2. Use the numerical keys to introduce the desired PLU number and then
press the PLU key to recall it.
Change the value of a PLU
1. When the message appears on the display, press the PLU key.
The unit weight value will flash.
2. Change the unit weight value according to previous procedure and press
PLU key to confirm and save.

WEIGHING ACCUMULATIONS M+
1. Place a weight on the weighing pan and input his weight, press the M+
key. When the scale gives a beep and the display shows the ACC
message, the data will be automatically stored.
2. Remove the weight from the weighing pan and place another one on
the pan. Input the unit weight and press the M+ key. When the scale
gives a beep and the display shows the message ACC, the data will
be automatically stored.
l If after each operation, the weight is not removed from the pan,
pressing the M+ key the scale will make a long beep and it can
not save the data of following weighing.
l The scale can store up to 180 weighings.
Total weighing accumulations MR
1. In weighing mode, press the MR key, the display WEIGHT will remain
at zero. The display PIECE WEIGHT will show and the
display PCS the total number of pieces.
2. The display WEIGHT will show the total weight accumulated. The
number located in top side of message ACC means the number of
weighing made.
3. Press again the MR key to exit from function without delete data.
(When the option CAL 1: MR REC is configured to exit) or press again
the MR key to exit and delete data.
4. If optional Printer LP-50 is connected to the scale, the total weight
accumulated and the total of pieces will be printed (When the option
CAL 1: MR REC is configured to delete)
