3. INSTALLATION
a) Unpack then product.
b) If present (depending on the model), it is necessary to unscrew and remove the locking screw for the transportation
placed under the scale, as shown in the figure below:
c) Level the platform by adjusting the adjustable feet until the bubble is in the centre of the level. The stability of the
platform is very important.
ALL THE CORNERS MUST REST IN A UNIFORM WAY. Carefully check that all feet fully rest on the ground and that the
platform, loaded on the corner, is not unstable (if a corner is not resting on the ground its relative foot is easier to turn).
3.1 POWER SUPPLY AND START-UP
The indicator can be powered with a fitted 240 Vac external power adapter or just with the fitted battery.
NOTE: it is advisable to completely recharge the battery (12 hours) with the first installation of the instrument.
TO POWER the instrument through the 240 Vac mains put the AC/DC power plug in the appropriate socket under the
scale and the power adapter in the 240 Vac mains socket.
TO TURN ON/TURN OFF the instrument press the ON/OFF key.
3.2 BATTERY POWERED
The weighing indicator can be operated from the battery if desired.
When the battery needs charging the symbol on the weight display will be empty. The battery should be charged
when the symbol is on. The scale will still operate for about 10 minutes after which it will automatically switch off to protect
the battery.
To charge the battery simply plug into the mains power. The scale does not need to be turned on.
The battery should be charged for 12 hours for full capacity.
You can find the symbol on the display to indicate the status of battery charging. When the scale is plugged into

6
the mains power the internal battery will be charged. If the symbol is full the battery has a full charge. If it is half the
battery is nearly discharged and empty indicates the battery should be charged.
As the battery is used it may fail to hold a full charge. If the battery life becomes unacceptable then contact your distributor
4. FRONT PANEL KEYS AND INDICATORS
FUNCTION OF THE KEYS
- It turns on/off the scale.
- Clears the displayed gross weight if it’s within +/- 2% of the total capacity.
- A secondary function of "Enter" key when setting parameters or other functions.
- If pressed for an instant it executes the semiautomatic tare.
- A secondary function of incrementing the active digit or selecting a value or
parameter when in setting mode.
- If pressed for an instant it allows linking a weight to the 100 percentile (see section
6.7).
- In the numeric input, it selects the digit to be modified, from left to right.
- If pressed for an instant it allows to execute the reference operation (see section
6.6)
- In the numeric input, it selects the digit to be modified, from right to left.
- It allows to convert in the configured secondary units of measure (see section 6.8).
- In the numeric input phase, it quickly clears the present value.
- If pressed for an instant it adds the value to the accumulation memory if the
accumulation function is not automatic.
- Secondary function (ESC) is to return to normal operation when the scale is in a
parameter setting mode.

5. SYMBOLS ON THE LCD DISPLAY
The LCD display has symbols which show the indicator’s functioning status; you will find the description for each symbol
below.
6. OPERATION
6.1 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 within +/- 10%
of the capacity is detected, it will be zeroed; if the weight is not within this tolerance, the display shows “Err 4” and the
present weight after a few instants.
6.2 SCALE ZERO FUNCTION
You can press the ZERO key at any time to set the zero point from which all other weighing and counting is measured,
within +/- 2% of power up zero. This will usually only be necessary when the platform is empty. When the zero point is
obtained the display will show the indicator for zero.
The scale has an automatic rezeroing function to account for minor drifting or accumulation of material on the platform
(see step “P4 AZn”, section 7.5). However you may need to press the ZERO key to rezero the scale if small amounts
of weight are shown when the platform is empty.
6.3 TARE FUNCTION
Zero the scale by pressing the ZERO key if necessary. The zero 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 when the “stable” is light. 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 "T" 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.
6.4 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.

6.5 TOTALISATION OF THE WEIGHT
The scale can be set to accumulate manually the weight on the scale by pressing the PRINT/M+ key (see step “AU”,
chapter 7.1).
The weight displayed will be stored in memory when the PRINT/M+ key is pressed and the weight is stable.
The display will show "ACC 1" while the weight will be printed, then the total in memory for 2 seconds before returning
to normal.
Remove the weight, allowing the scale to return to zero and put a second weight on. Press the PRINT/M+ key, the
display will show " ACC 2" and then the new total.
Continue until all weights have been added.
To view and print the totals in memory press PRINT/M+ key when current scale in zero status (Zero indicator on)
To clear the accumulated total weight, press the PCS key when show total values.
Scale automatically exit form the visualization of the total values after few seconds.
NOTE:
- The totalisation functions with a minimum weight of 20d.
- The maximum number of totalisations is 999 while the maximum total value which may be accumulated is
999999.
Once reached these limits, one should clear the total; by pressing PRINT/M+ the message “AdErr” will appear on
the display.
- The total values will be cleared when it’s turned off.
6.5.1 MANUAL OR AUTOMATIC TOTALIZATION
The operation of accumulation, normally done manually with key PRINT/M+, can be done automatically when the
weight is stable. In regards to the choice of the totalisation execution mode, see step “AU”, section 7.1.
6.6 COUNTING PIECES
Through the reference function it’s possible to use the scale as a piece counter.
COUNTING PROCEDURE
The operations to be carried out are the following:
1) Place the empty container on the scale and press TARE to tare it.
2) Check that the zero is on the display and put the quantity of pieces chosen for the SAMPLE on the scale and
press PCS key .
3) The display suggests a REFERENCE QUANTITY. The possible options are: 10, 20, 50, 100, and 200.
4) Press TARE the number of times needed to reach the desired sample size.
5) Press ZERO; the display will indicate "- - - - - -" and the indicator will calculate the Average Piece Weight (APW).
After a few instants the display will indicate the quantity selected put on the platform.
6) Add the rest of the items to count in the container and whose value will appear on the display.
7) Unload the scale, the APW will remain stored in memory for the next counting of similar pieces, without having to
repeat the REFERENCE operation.
8) By pressing the MODE key one switches from the display of the number of pieces to the display of the average
piece weight and of the net weight.
) Per cancel or to carry out a new reference operation, press the PCS key and repeat the operations as
describe in point 1).

6.7 SAMPLE WEIGHT PERCENTILE
In this functioning mode, the display shows the weight expressed as a percentile, comparing it with a reference weight
for which the 100 percentile has been already linked.
MATCHING PROCEDURE
-Put the reference weight on the scale .
-Press the % key when the “stable” indicator is on.
-The scale has executed the percentile matching and displays the percentile of the weight on the scale.
-Unload the scale: the following weighs will be expressed as a percentage in reference to the reference weight.
-To cancel or execute a new matching operation, press the % key and repeat the operations described above.
6.8 UNIT OF MEASURE CONVERSION
