5. POWER SUPPLY AND START UP
5.1 POWER SUPPLY
The instrument can be powered with a 6 Vdc tension supplied from an AC/DC external adapter which should be connected
to the 110-240 Vac mains voltage. Safety norms must be respected for the connection to the mains voltage including the
use of a line which has to be free from noise generated by other electronic equipment.
t is also possible to power the scale through the rechargeable built-in battery.
6V RECHARGEABLE BATTERY FEATURES
Material Lead
Power 4,5 Ah
Output 6 V
THE BATTERY MUST ONLY BE REPLACED WITH AN ORIGINAL FROM THE MANUFACTURER.
n order TO POWER the instrument through the 110-240Vac mains or TO RECHARGE the 6V battery, insert the plug end
of the AC/DC power adapter into the socket in the lower part of the indicator (chapter “ NSTALLAT ON”) and the adapter in
your main current source.
Do not connect other eq ipment to the same socket as the one that the adapter is in.
Do not step on or cr sh the power s pply cable.
5.2 TURNING ON / OFF THE INSTRUMENT
TO TURN ON the scale press the MODE/C key until the indicator turns on; then release.
The display shows:
XX.YY is the installed software version.
The instrument turns on all the display segments and symbols.
MAX XXX.XXX capacity of channel 1
bt XXX in which XXX is a number from 0 to 100 which indicates the battery level (if present).
The scale 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, with a non approved instrument the display
shows the present weight after a few instants, while with an approved instrument “ZEro” is shown continuously on the
display, until the weight does not re-enter within this tolerance; the auto zero function at start-up may be disabled in the set-
up environment (only with non approved instrument); see SEt P >> ConFiG >> PArAM >> A to-0 parameter
(TECH.MAN.REF.).
By pressing the ZERO key for an instant while the version is shown in the display, the indicator will show the following in
this order:
XX.YY in which XX indicates the instrument type, YY indicates the metrological software version.
XX.YY.ZZ is the installed software version.
APd is the name of the installed software.
bt XXX in which XXX is a number from 0 to 100 which indicates the battery level (if present).
-K- X.YY in which K identifies the type of keyboard: K=0 5-key keyboard.
X.YY is the installed software version.
After this, it shows the programmed capacity and the minimum division, “hi rES” (in case of NOT approved instrument) or
“LEGAL” (in case of approved instrument), the g gravity value, and finally it executes a countdown (self-check).
TO RESTART the scale keep the MODE/C key pressed for 8 seconds long: the indicator will turn off, then release the key
and the indicator will automatically turn on.
TO TURN OFF the scale keep the MODE/C key pressed until the “- OFF–“ message appears on the display; then release
the key.

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 D V S ON, STABLE (instability ~ led off) and
VAL D (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 D V S ON, STABLE (instability ~ led off)
and VAL D (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: f 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 a tomatically cancel the tare val e; 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 nloading the scale, may also be 0.
In case of MANUAL TARE the net weight before nloading the scale m st 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.

-Press the MODE/C key many times until the display shows the message “SAVE?”.
-Press MR to confirm the changes made or another key for not saving.
The instrument stores the last selection made, also after it is turned off.
8.3 LIMITATION OF THE TARE FUNCTIONS FOR DIRECT SALE
With approved instrument, it is possible to limit the tare functions, by setting “yES” in the step SEt P >> d.SALE
(TECH.MAN.REF.). n this case, all the tare operations will be disabled.
With approved instrument, the d.SALE step is read-only.
8.4 AUTO POWER OFF FUNCTION
t is possible to automatically turn off the scale (from 1 to 255 minutes), or disable it; the auto power off takes place when,
with nloaded scale, the weight has not been moved or a key has not been pressed for the time set: the display shows the
“- OFF – “ blinking message and an acoustic signal is emitted; after this the scale turns off.
For the setting, follow the procedures below:
- Turn on the scale, press 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
“En.SAVE” parameter.
-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
“AutoFF” parameter.
-Press MR to enter the parameter.
-With the ZERO or TARE keys select the possible options: “diSAb” (auto switch-off disabled), “EnAb” (auto switch-off
enabled).
-Confirm with MR; if “EnAb” has been selected, one will be asked to enter the number of minutes after which the scale
should turn off: enter a number between 1 and 255 (using the M+ key to select the digit to be modified and ZERO/TARE
to decrease/increase it) and confirm with MR.
-Press many times the MODE/C key until the display shows “SAVE?”.
-Press MR to confirm the changes made or another key for not saving.
8.5 LOW BATTERY WARNING
One should set the supply mode by setting the step SEt P >> ALiM.
The charge level is shown in the weighing phase by the battery symbol:
- : battery is charged.
- : battery is partially charged.
- : battery is discharged: connect the scale to the mains for recharge the battery or replace it.
Furthermore, for a few seconds the "Low.bat " message appears on the display (minimum level voltage).
When recharging the battery, the display shows the recharging phase below:
RECHARGING PHASE:     …
RECHARGE IS COMPLETED:
NOTES:
- While recharging, the instrument can be used as usual.
- The instrument automatically turns off when the voltage goes below the minimum level.
- t’s possible to view the recharge percentile of the battery by pressing the ZERO key upon start-up (see the section
“POWER SUPPLY AND START-UP”).

8.6 MULTI RANGE FUNCTIONING (for legal for trade approved instr ments)
The multi range functioning allows to subdivide the scale capacity in two or three ranges, each which is up to 3000
divisions, improving in this way the first range division in the dual range and the first two ranges in the triple range.
For example, with a 30 kg cell platform it is possible to approve the weighing system with:
-A single range: 6 kg capacity and 2 g division (3000 div.).
-Dual range: 6 / 3 kg capacity and 2/1 g division (3000 + 3000 div.).
-Triple range: 15 / 6 / 3 kg capacity and 5/2/1 g division (3000 + 3000 + 3000 div.).
NOTES:
- For the approval of the weighing system in dual and triple range the cell must have better technical features in comparison
to the cell used for the approval in a single range.
The multirange functioning is shown by the turning on of the relative symbol on the display which identifies the range in
which one is operating; by passing to the second range, the second range division is enabled; by passing to the third range,
the third range division is enabled. At this point the first range division is restored only by passing by the gross zero of
the scale.
- The selection of the range number with multirange functioning is made during the scale’s calibration (TECH.MAN.REF.).
8.7 CONVERSION OF THE UNIT OF MEASURE
t is possible to execute the weight conversion from the unit of measure of the scale to pounds and vice versa, by pressing
the MODE/C key.
To enable or disable this function, follow the procedure below:
-Turn on the scale, press the TARE key while the firmware version is displayed (the display shows the “F.ModE” step).
-Press MR to enter the step.
-Press ZERO many times (to scroll forwards through the parameters) or TARE (to scroll backwards) until one finds the
“un.ConV” step.
-Press MR to enter the parameter.
-With the ZERO or TARE keys select the possible options: “diSAbL” (disables the unit conversion), “EnAbLE” (enables
the unit conversion).
-Confirm with MR.
-Press the MODE/C key many times until the message “SAVE?” is shown on the display.
-Press MR to confirm the changes made or another key to not save.
NOTES:
-The present total will be cleared when the conversion takes place.
-The conversion causes the state of instability of the weight.
-The conversion can take place for any unit of measure set during the calibration.
-With approved instrument the weight in pounds is displayed for 5 seconds, after which the display returns to the scale
unit of measure.
8.8 DISPLAY OF METRIC DATA (inFO)
The scale is fitted with a function named “ NFO”, thanks to which it is possible to view the configuration metric data:
-Keep the MODE/C key pressed until the display shows “inFo”, and release.
-The capacity value of the first range will appear.
-Press the ZERO key to scroll the following data, in this order:
Capacity 1° range  Minimum weigh 1° range  Division 1° range 
Capacity 2° range  Minimum weigh 2° range  Division 2° range 
Capacity 3° range  Minimum weigh 3° range  Division 3° range 
Capacity 1° range ………
-Press the TARE key to scroll backwards the metric data.
-Press the MODE/C key to return to weighing.
NOTES:
-The minimum weigh corresponds to 20 net weight divisions.
-The data of the second and third range appear only if actually configured.

9. TOTALISATION
nside the F.ModE >> totAL step of the setup environment it is possible to set the parameters for the function of
totalisation:
tot.Mod: TYPE OF TOTAL ZAT ON
t is possible to select the type of totalisation: manual (MAnuAL) or automatic (Auto).
n.WEiGh: NUMBER OF WE GHS
f one sets this parameter as “yES”, for each operation of totalisation the number of weighs and the total weight are
displayed. f the total weight has more than 6 digits, its visualisation takes place in two stages.
f one sets the parameter as “no”, for each operation of totalisation only the "-tot-" message is displayed.
WAit.St: WA T STAB L TY
Once one has set the wait stability time with a value different from 0, each operation of totalisation will be executed only
if the weight is in stability. When the weight is not stable and M+ key is pressed, the unstable weight is displayed blinking
and one is not allowed to press any key; the totalisation will remain pending. f the wait stability time is expired and the
weight is not stable, the present accumulation will be aborted with the display of the “unStAb” message and error beeping.
f one sets this parameter with the value 255, the waiting stability time is infinite on each accumulation.
Once one has set the wait stability time at 0, if one press the M+ key and the weight is not in stability, the operation of
totalisation is instantly aborted with the display of the “unStAb” message and error beeping.
NOTE: This parameter takes effect only if the manual totalisation has been set.
MAx.tot: NUMBER OF CONSECUT VE TOTAL SAT ONS AFTER WH CH THE TOTAL S AUTOMAT CALLY CLEARED
After having carried out the number of totalisations set in this step, the accumulated total is shown on the display and
cleared; one can set a value between 0 and 255.
NOTE: the value 0 disables the function.
9.1 OPERATIONS OF TOTALISATION
This scale allows to totalize the weight in load and unload.
Totalisation in load:
f the manual totalisation has been set, in order to carry out the totalisation it is necessary to load the weight on the scale
and press the M+ key; then the weight is accumulated in the total.
f the automatic totalisation has been set, there is the automatic acquisition of the stable weight loaded on the scale and
then the accumulation of the weight in the total.
To totalize, the net weight must be:
- at least 1 division with not approved instrument and manual totalisation;
- at least 10 divisions with not approved instrument and automatic totalisation;
- at least 20 divisions with approved instrument.
Totalisation in nload:
f a tare is active, one can totalize also negative values of weight: after having executed the tare, by removing part of the
weight from the scale, the negative value of the unloaded weight is displayed and it is possible to totalize this value. The
totalisation is executed by pressing the M+ key if the manual totalisation has been set or automatically when the weight is
stable if the automatic totalisation has been selected.
To totalize, the negative net weight must be:
- at least 1 division with not approved instrument and manual totalisation;
- at least 10 divisions with not approved instrument and automatic totalisation;
- at least 1 division with approved instrument and manual totalisation;
- at least 20 divisions with approved instrument and automatic totalisation.
Note: to totalize the negative net weight, with not approved instrument the gross weight must be greater than or equal to
zero; with approved instrument the gross weight must be at least 20 divisions.

APD series bench scale APD_01_11.05_EN_U
15
9.2 REACTIVATION OF THE TOTALISATION
To avoid undesired totalisations, the M+ key is active just once; its reactivation depends on the setting of the “rEACt”
parameter (TECH.MAN.REF.) in the setup environment. t can be reactivated after the passing of the weight by the zero of
the scale, by instability of the weight or always.
f the reactivation on instability has been set, the totalisation is reactivated by instability of the weight with manual
totalisation or by instability and change in weight of 10 or 20 divisions (respectively with not approved or approved
instrument) with automatic totalisation.
By pressing the M+ key again, witho t having reenabled the totalisation, the "no.0.unS" error message is displayed and
an acoustic signal is emitted.
NOTES:
-f the gross or net weight in absolute value is less than the requested minimum weight, by pressing the M+ key the
display shows the “LoW” error message.
-f the scale is in the under load or over load status, by pressing the M+ key the display shows the “un.oVEr” error
message.
9.3 VISUALIZATION OF THE TOTAL
By pressing the MR key one can temporarily view on the display the number of weighs and the net weight total. f the total
weight has more than 6 digits, the visualisation of this value takes place in two stages.
9.4 ZEROING OF THE TOTAL
The instrument increases the total weight upon each totalisation; it can be cleared in the following modes:
- by executing the Mc (memory clear) function: press in rapid succession the MR and MODE keys (the “tot.Clr” message is
displayed);
- by executing the conversion of the unit of measure;
- by turning off the instrument;
- automatically after having carried out the number of totalisations set in the <<MAX.tot>> step.

n.oVEr One is trying to totalize with the weight in underload or in overload, in other words, with a weight of 9 divisions
greater than the capacity or of 100 divisions below the gross zero.
LoW Weight less than the minimum weight provided for the totalisation or the transmission of the string, standard
or extended, upon pressing of the print key.
no.0. nS Weight not passed by net 0 or by instability.
ErMot Unstable weight during the calibration.
PrEC. t is displayed if one tries to calibrate the zero point without first having confirmed the number of calibration
points.
ErPnt During the acquisition of a calibration point a null value has been read by the converter.
Er – 11 Calibration error: a too small sample weight has been used; it is advisable to use a weight equal to at least
half of the scale capacity.
Er – 12 Calibration error: the acquired calibration point (tP1 o tP2 o tP3) is equal to the zero point (tP0).
Er – 37 The number of converter points per scale division is less than two. Carry out again the calibration with special
attention to the capacity and the division.
Er – 39 t is displayed when the instrument has not yet been calibrated and initialized.
Press the TARE key when the instrument displays “Er – 39” to enter the technical set-up environment. Carry
out the initialization of the indicator (“dEFAu” parameter) and finally the programming of all the parameters of
the set-up environment and the calibration.
Er – 85 t is displayed when the instrument has been initialized but not yet been calibrated.
Press the TARE key when the instrument displays “Er – 85” to enter the technical set-up environment and
carry out the calibration.
C.Er. – 36 During the calibration some internal negative points have been calculated:
- the calibration point is less than the zero point.
- the signal is negative (check the connections)

The weight in underload (i.e. a weight of 100 divisions below the gross zero, if the instrument is approved) is
notified through this message and by an acoustic signal.
oVEr
(blinking)
The weight in overload (i.e. a weight of 9 divisions greater than the capacity) is notified through this message
and by an acoustic signal.
