WEIGHT INDICATOR
11 CONNECTION TO TRANSDUCER
After having followed the instructions regarding the platform or the load receiver, the screened cable leading from the load
cell(s) must be connected to the instrument through the CELL1 terminal board and the CELL1 (see “CONNECTION
SCHEME” section) through the relative input (“INSTALLATION” section).
The CELL1 terminal board of the indicator may be connected to the 6-wire load receiver (with use of SENSE), or simply 4wire; for this, through jumper J10 and J11 it is possible to choose whether to short-circuit the SENSE with the POWER
SUPPLY (jumpers closed) or not (jumpers open).
The sense allows compensating for any drops in voltage in the part of the cable that connects the instrument to the
transducer. It is useful when the distance between the indicator and the transducer is greater than 10 m.
The 4-pin connectors instead allow just the 4-wire connection.
To make the connection qualified personnel must open the instrument (see paragraph 8.2 “CONNECTION SCHEME”).
Normally the indicator comes already connected to the scale and is ready to use.
If the instrument is approved for table mounting, the access to the connection will be bound by SEAL. If the connection is
not sealed, like in the case of the model for panel mounting, the load receiving device will have an identification label that
shows the indicator it is connected to.
Technical Note: on the external power cable, on the battery cable (near the terminal on the CPU card), and on the
connection cable to the load receiving device (near the cable entrance of the instrument) some ferrite rings are installed or,
at times, supplied together with the instrument to reduce possible radio frequency disturbances.
All cables must be wound at least once around the ferrite ring before being connected to the terminal board; the cable
screen must be left outside of the ferrite and should be connected to the relevant ground pin.

17 BASIC FUNCTIONS
17.1 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.
17.2 TARE OPERATIONS
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 relative keys turn on.
In any case a new tare operation cancels and substitutes the previous one.
NOTE: The semiautomatic tare will be acquire only if the weight is AT LEAST A DIVISION, STABLE (instability ~ led off)
and VALID (in other words, the OVERLOAD condition should 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 extended
keyboard:
Confirm with the ENTER/PRINT key; the value will be subtracted from the weight present on the plate and the relative pilot
lights will turn on.
If the entered value is not a multiple of the scale’s minimum division, it will be rounded off.
In any case a new tare operation cancels and substitutes the preceding one.
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.
- press C without unloading the scale.
- enter a manual tare equal to 0.
NOTE: it is possible to automatically cancel the tare value; see the following section.
SELECTION OF LOCKED/UNLOCKED/DISABLED TARE
Normally, when a tare value is entered (automatic, manual, or from storage) 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 disable the tare functions.
With the UNLOCKED tare:
In case of SEMIAUTOMATIC TARE the net weight, before unloading the scale, may also be 0.
In case of MANUAL TARE or FROM DATABASE the net weight before unloading the scale must be of at least 2
stable divisions.
To set the type of tare:
press in sequence the "F"+ "2" keys: the display shows "tA-L" = BLOCKED TARE is selected; by pressing the same keys
again the display shows "tA-U" = UNBLOCKED TARE is selected.
The indicator stores the last selection made, also after it is turned off.
17.3 LIMITATION OF THE TARE FUNCTIONS
- With a non approved instrument, the tare operations are unlimited, in other words, these are always active.
The same operations may be executed with an approved instrument, if one selects: SEtuP >> d.SALE >> no. (see
TECHNICAL SET-UP (TECH.MAN.REF.)
22
TPWATEX
- With approved instrument, it is possible to limit the tare functions, selecting: SEtuP >> d.SALE >> yES
(TECH.MAN.REF.) the tare operations will have the following specifications:
SCALE CAPACITY
< 100kg
≥ 100kg
FUNCTIONING
All the tare functions are disabled
- The SEMIAUTOMATIC TARE value can not be modified with a
manual tare or from database.
- The manual tare or from database can be entered or modified
only with an UNLOADED scale.
With approved instrument, the d.SALE step is not displayed.
17.4 AUTO POWER OFF FUNCTION
It is possible to automatically turn off the indicator (from 1 to 255 minutes), or disable it; the auto power off takes place
when, with unloaded 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 indicator turns off.
For the setting, follow the procedures below:
- Turn on the scale, press the TARE key while the firmware version is displayed
- Scroll the parameters with the ZERO key until the F.ModE menu is shown on the display.
- Press ENTER/PRINT 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 ENTER/PRINT 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 ENTER/PRINT; if “EnAb” has been selected, one will be asked to enter the number of minutes after which
the indicator should turn off: enter a number between 1 and 255 (using the MODE key to select the digit to be modified
and ZERO/TARE to decrease/increase it) and confirm with ENTER/PRINT.
- Press many times the C key until the display shows “SAVE?”.
- Press ENTER/PRINT to confirm the changes made or another key for not saving.
17.5 LOW BATTERY WARNING
The indicator is able to recognize whether it is powered from the mains or through a battery; in this last case the battery
charge level (from “bt 9” to “bt 0”) is shown when the indicator is turned on.
On the display the battery symbol (
) is always displayed indicating its charge level:
- 3 notches correspond to the bt 8, bt 9 values
- 2 notches correspond to the bt 6, bt 7 values.
- 1 notch corresponds to the bt 3, bt 4, bt 5 values.
- 0 notches correspond to the bt 0, bt 1, bt 2 values.
When this level becomes equal or less than bt 2, or during the weighing phase, "Low.bat " appears on the display (in other
words the voltage goes below 5,9 V), one should connect the indicator to the mains in order to recharge the battery.
While recharging, the instrument can be used as usual.
NOTE: the instrument automatically turns off when the voltage goes below 5,8V.
17.6 "TILT" DEVICE
The TILT is a device which inhibits the indicator’s weighing system and starts working when the instrument’s inclination is
greater than 2% for the pallet truck application or 5% for application on lift trucks.
Central dashes are shown on the LED display, and at regular intervals of about 5 seconds, an error sound signal is emitted.
The activation of the tilt alarm has a delay of about three seconds from the detection of the exceeding inclination.
23
TPWATEX
17.7 MULTI RANGE FUNCTIONING (for legal for trade approved instruments)
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 10 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: 6 / 3 /1,5 kg capacity and 2/1/0,5 g division (3000 + 3000 + 3000 div.).
NOTE: 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 LED 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.
NOTE: The selection of the range number with multirange functioning is made during the indicator’s calibration
(TECH.MAN.REF.).
17.8 PRINTING (only with optional board)
If a printer is connected (in a safe zone) it is possible to print the programmed weight data, for example:
- 4 heading lines of 24 characters
- GROSS weight
- TARE weight
- NET weight
- ticket number
- a CODE 39 barcode (with TPR thermal printer).
Besides the generic printing described above, each single functioning mode will have some specific printouts, which are
described in the operating mode.
Printing with NON approved scales.
In order to print with non approved scales the following conditions must exist:
- the weight must be stable;
- the gross weight must be >= 0;
NOTE: In the totaliser modes in order to print the totalised weight the following must take place:
- the weight must be stable;
- the net weight must be >= of a division;
Legal for Trade scale printing.
In order to be able to print with a legal for trade scale the following conditions must exist:
- the weight must be stable;
- the net weight must be >= the minimum weight (minimum of 20 divisions).
the printing is reactivated depending on how the “rEACT” parameter has been set in the set-up environment: passage by
zero of the NET weight, weight instability, or always.
To configure the printouts, go to the section 8 “PROGRAMMING THE PRINTOUTS” in the technical manual
(TECH.MAN.REF.).
Notes:
- The printing is confirmed by the indication on the display of the "Print" message.
- If the printout is not reenabled the display shows the "no.0.unS" message
- With the weight unstable the display shows the "unStAb" message.
24
TPWATEX
17.9 REENABLING THE PRINTOUTS AND THE INDICATOR FUNCTIONS
While using the indicator, it is possible to incur into the “no.0.unS” error shown on the display along with an acoustic signal;
this means that the printing or the function which one wants to carry out must be reenabled (in order to avoid unwanted
executions).
It is possible to set the reenabling in different ways: “passage by zero of the net weight”, “weigh instability” or “always”.
Follow the procedure below:
- Turn on the scale, press the TARE key while the firmware version is displayed
- Scroll the parameters with the ZERO key until the F.ModE menu is shown on the display.
- Press ENTER/PRINT to enter the menu.
- Press ZERO many times (to scroll forwards through the parameters) or TARE (to scroll backwards) until one finds the
“rEACt” parameter.
- Press ENTER/PRINT to enter the parameter.
- With the ZERO or TARE keys select the possible options: “ZEro” (passage by zero of the net weight), “inSt” (instability),
ALWAyS.
- Confirm with ENTER/PRINT.
- Press the C key many times until the message “SAVE?” is shown on the display.
- Press ENTER/PRINT to confirm the changes made or another key to not save.
17.10 DISPLAY OF METRIC DATA (inFO)
The indicator is fitted with a function named “INFO”, thanks to which it is possible to view the configuration metric data:
- First range capacity, first range minimum weigh, first range division.
- Second range capacity, second range minimum weigh, second range division.
- Third range capacity, third range minimum weigh, third range division.
NOTES:
- The minimum weigh corresponds to 20 net weight divisions.
- The data of the second and third range appear only if actually configured.
To view the metric data:
- keep the 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 ð Minimum weigh 1° range ð Division 1° range ð
Capacity 2° range ð Minimum weigh 2° range ð Division 2° range ð
Capacity 3° range ð Minimum weigh 3° range ð Division 3° range ð
Capacity 1° range ð………
- Press the TARE key to scroll backwards the metric data.
- Press the ENTER/PRINT or C key to return to weighing.
17.11 STORED TARE MEMORY VALUES
It’s possible to store up to 10 tare memory values, identified by the location numbers 0 to 9, which the user can recall
when needed.
To insert or modify a tare value:
- press the keys “F”+ “9” in sequence - the display will indicate tM n. in which n is the storage number to be entered. For
example, by pressing “0”; the display will indicate "00000" or any value that already exists in the tare memory location
"0."
- Insert the tare value with the numeric keyboard (with the C key one quickly zeros the entered value) and press
ENTER/PRINT.
- Repeat the sequence for the following memory positions.
If the entered value is not a multiple of the scale’s minimum division, it will be rounded down if equal or greater
than half of the division, and rounded up if less.
RECALLING STORED ARE VALUES
To recall a stored value:
- press the keys “F” + “1” in sequence. The display will indicate "tP n." in which n is the storage number to be entered.
Press the key (0 - 9) corresponding to the desired tare value location in memory; the tare will be enabled.
25
TPWATEX
17.12 ENTERING THE IDENTIFICATION CODE
It is possible to insert 2 numerical codes of up to 10 digits in length (maximum) to use as a reference during printing:
- Press the “F”+ “3” keys in sequence. The display will indicate "IId n" in which n identifies the code number which one
wants to enter.
- Press 1 or 2: the display will show 00000 or the last entered value.
- Enter the code through the numeric keyboard and confirm with ENTER/PRINT or press C to exit without saving the
modifications. While entering, just the last 6 digits entered will be displayed; in any case it is possible to scroll all the digits
using the MODE key.
After its entry, the code will automatically be printed with its abbreviation (ID1 or ID2) in each printing that will be made. It is
also possible to set the automatic cancellation of the code after the printing made (see the following paragraph).
IN ANY CASE, the stored codes are cancelled when the instrument is turned off.
NOTES:
- The values between 0'000'000'001 and 9'999'999'999 are valid; by entering 0'000'000'000 the code is cancelled.
- In the TOTALIZER functioning mode, the codes will be printed only in the printing of the total.
LOCKED / UNLOCKED CODE SELECTION
Normally the code is LOCKED, in other words once it is set it remains stored (and therefore printed) until it is cancelled or
until the instrument is turned off. In any case it is possible to make it so the code is cancelled as soon as it is printed
(UNLOCKED CODE).
- Press the keys “F” + “4” in sequence; the display indicates "MId n”.
- Press "1"; the display indicates "Id1 U" = CODE 1 UNLOCKED.
- Press the same keys again: the display indicates "Id1 L" = CODE 1 LOCKED.
- Repeat the same operations for CODE 2. .
17.13 KEYBOARD LOCK
It is possible to disable the keyboard functions (except for the C key for turning on and off) in order to avoid accidental
pressing of the keys:
- Press in sequence the F and 0 keys: the display shows “LoCk.kEY” for an instant (LOCKED KEYBOARD).
- If in this status a key is pressed the message "LoCkEd" is shown on the display.
- To UNLOCK the keyboard, press again the F and 0 keys: the display shows “unL.kEY” for an instant (UNLOCKED
KEYBOARD).
NOTE: The keyboard may be disabled also by closing an input, if programmed, of the optional expansion board: refer to the
“inPutS" parameter of the set-up environment (TECH.MAN.REF.); in this case however by pressing a key, the message
“LoCkEd” does not appear on the display.

Press ENTER/PRINT to confirm the changes made or another key to not save.
NOTE: If there is a printer, once the functioning mode is selected, the relative printout is automatically enabled, depending
on the type of printer selected in the SEtuP >> SErIAL >> PrMODE (TECH.MAN.REF).
18.1 kg/lb CONVERSION (Std)
By pressing "MODE" key the value is converted from kg to lb and vice versa.
NOTES:
- with APPROVED instrument in single range the weight in pounds is displayed for 5 seconds, after which the display goes
to kilograms. During the viewing in pounds it is not possible to print the weight (when pressing ENTER/PRINT the message
“ConV” is shown and an acoustic signal is emitted.
18.2 NET/GROSS SWITCH (ntGS)
If a tare is set by pressing the MODE key, for about 5 second interval, the gross weight is displayed.
NOTE: While the gross weight is being viewed it is not possible to print.
18.3 SETPOINT ON GROSS WEIGHT (StPG)
By selecting this functioning mode, in the normal scale status one enables the function of the TTL digital outputs on the
GROSS weight.
Through the optional board, it is possible to use up to 4 outputs.
In the outPut menu of the SET-UP environment (TECH.MAN.REF.), one sets the functioning mode of each output: none,
with hysteresis (separate enabling and disabling set points), without hysteresis (single set point).
Furthermore it is possible to set the status of the outputs (normally open or normally closed), or the type of check (direct or
upon weight stability).
27
TPWATEX
MODE WITHOUT HYSTERESIS

TPWATEX
NOTES: - the disabling set point must be ≤ the enabling set point.
- if in the disabling set point one enters and confirms a value greater than the enabling one, the instrument will
automatically set the same value in the enabling step.
- if in the enabling set point one enters and confirms a value less than the enabling one, the instrument will
automatically set the same disabling value.
- if one enters a set point with a number of divisions not coherent with the set minimum division it will be
rounded up to the multiple of the minimum division closest to it.
- if one enters a disabling set point greater than the enabling one it will be corrected and the anomaly is
indicated through the “ModiFY” message at the exit of the configuration MENU of the SET POINTS.
The 0 value is valid both in the enabling as well as in the disabling set points, and just set points equal or greater than zero
are accepted.
18.4 SET POINT ON NET WEIGHT (StPn)
Functions the same as the previous one, but the check is made on the NET weight.
18.5 INPUT/OUTPUT (in out)
Simple display functioning mode with in / out weighing function: the indicator acquires two weight values through the
confirmation of the operator and calculates the difference, automatically printing the data (if the presence of a printer has
been configured).
Once the in/out mode has been selected, the message “tyPE” is shown and one is asked to select with ENTER/PRINT the
printing mode of the acquired data:
- “G.t. gross/tare:
GROSS
Greater weight with unit of measure
TARE Lesser weight with unit of measure.
NET Difference between GROSS and TARE with unit of measure
- 1st.2nd first weigh/second weigh:
WEIGH 2 Second weight with unit of measure.
NET Difference without sign between WEIGH 1 and WEIGH 2 with unit of measure.
- in.out input/output:
INPUT First weight with unit of measure.
OUTPUT Second weight with unit of measure.
NET Zero weight with unit of measure >> if WEIGH 1 = WEIGH 2
INPUT NET
>> if WEIGH 1 > WEIGH 2
Difference without sign between INPUT and OUTPUT with unit of measure.
OUTPUT NET
>> if WEIGH 1 < WEIGH 2
Difference without sign between INPUT and OUTPUT with unit of measure.
PROCEDURE:
- With the key one acquires the first weight, on the display is shown “ - - 1 - - -“ accompanied by a prolonged beep;
- By pressing 2 one acquires the second weight and on the display is shown “- - 2 - - -“ accompanied by a prolonged
beep.
- NOTE: The acquisition of the second weight is made only if the setting of the rEACt parameter in the set-up
environment has been respected (passage by zero of the weight, instability, or always); see “REENABLING OF THE
PRINTOUTS AND THE INDICATOR FUNCTIONS” section.
- When the second weight is acquired, the data printout is commanded:
It is possible to interrupt the weighing cycle by pressing the key after the acquisition of the first weight: On the display the
message “ CLEAr ” is shown accompanied by a prolonged beep. Press ENTER/PRINT to confirm the cancelling of the first
acquired weight or another key to not confirm.
29
TPWATEX
NOTES:
The first weight is acquired if:
- With a NON APPROVED scale one has a STABLE weight and GREATER than 0.
- With an APPROVED scale one has a STABLE weight and GREATER than 20 divisions.
The second weight is acquired if:
- With a NON APPROVED scale one has a STABLE weight and GREATER than 0.
- With an APPROVED scale one has a STABLE weight and GREATER than 20 divisions.
- if the setting of the rEACt parameter in the set-up environment has been respected (passage by zero of the weight,
instability, or always); see “REENABLING OF THE PRINTOUTS AND THE INDICATOR FUNCTIONS” section.
- the tare operations are DISABLED.
18.6 REPEATER (MAStr)
The system is made up of one indicator (called SLAVE), connected to one or more weighing system, which communicates
with another indicator (called MASTER) which acts as weight repeater, on which it is possible to view the weight of the
connected scale.
In the SLAVE, instead, one needs to set a different functioning mode than the “MAStr” and enter the code 01 in SEtuP >>
SeriAL >> CoMPC >> PCModE >> 485 (see set-up environment, TECH.MAN.REF.).
FUNCTIONING
When turned on, the MASTER predisposes itself for the connection to the SLAVE present (“ECo 1” message appears,
indicating that it’s trying to detect the SLAVE): when at least the SLAVE is detected, it positions itself on it and repeats its
weight.
About every 10 seconds, the message “SCA 1” appears, indicating that the weight on the slave is being displayed.
By pressing the keys on the MASTER, these are repeated also on the SLAVE.
WARNING:
- if the instrument is or if the radio signal does not reach the MASTER, on the same display the “ECo 1” message is
displayed indicating that it’s trying to detect the SLAVE.
- If the connection is lost with the SLAVE, the MASTER will try to reconnect it;
- If the automatic switch off has been enabled in the MASTER, after about 5 minutes that one is trying to connect with the
SLAVE (in other words the ECo-1 message appears on the display), it turns off.
EXECUTION OF THE PRINTOUTS
If there is a printer on the master, it’s possible to execute on it the printouts configured in the active slave. In order to do
this, one should configure the printout on the SLAVE and in the master select the type or printer in the SEtuP >> SEriAL
>> CoMPrn >> PrModE parameter, TECH.MAN.REF.
The selection of this parameter excludes the printouts on the active slave.
18.7 ALIBI MEMORY (ALibi) (OPTIONAL)
(The mode foresees the use of a printer of a PC)
The alibi memory allows filing the transmitted weight values in the computer for data processing and/or integration. The filed
values may then be recalled from the PC serial line or directly on the indicator’s display for a following check.
The storage of a weigh takes place either following the reception of the serial command or following the pressure of the
ENTER/PRINT key: the indicator transmits on the PC serial line the gross and tare weights and an ID which clearly
identifies the weigh.
The ID has the following format:
<Rewriting number> — <Weigh number>
Rewriting number: number of 5 digits which may go from 00000 to 00255; it indicates the number of complete rewritings of
the alibi memory.
Weigh number: number of 6 digits which may go from 00000 to 131072; it indicates the weigh number in the current
rewriting of the alibi memory
With each storage the weigh number is increased of 000001; when this reaches the 131072 value, it restarts from 000000
and the rewriting number increases of 00001.
30
TPWATEX
Example:
If the stored weigh is the following:
“PIDST,1, 1.000kg, 1.000kg,00126-131072”
and the following will be:
“PIDST,1, 1.000kg, 1.000kg,00127-000000”
The storage of a weigh is possible only if the weight is stable, valid (in other words not in under load nor in overload) and if
the gross weight is equal or greater than zero. If these conditions are not respected:
- in the response to the PID serial command one has "NO" in the place of the ID.
- there is no transmission if ENTER/PRINT has been pressed.
When the weight is transmitted with the ID following the pressing of the ENTER/PRINT key, the display shows for about 2
seconds the message " tr.id ", and the transmitted string is the following:
<ESC>[II]PIDSS,B,LLLLLLLLLLUU,YYTTTTTTTTTTUU,(ID | NO)<STX>.
See the following section “Serial commands” for the string description.
NOTES:
- The alibi memory can store up to 131072 weighs; then one has the rewriting from the beginning.
- With approved instrument, the storage of the weigh and the following transmission of the ID to PC by pressing a key is
possible only if the printout is active (or passage from 0 or weight instability and minimum weight of 20 divisions).
- With approved or not approved instrument, the storage of the weigh through the PID serial command is always possible
for all the weighs from 0 to full range value.
READING OF THE WEIGHS CARRIED OUT
In order to read the information relative to the weighs carried out:
- Press the MODE key.
- The message "rew.id" appears; now one should enter the rewriting number (from 00000 to 00255) and press
ENTER/PRINT.
- The message “ id “ appears; now one should enter the weigh number (from 000000 to 131072) and press
ENTER/PRINT.
- Now it is possible to view on the display the weigh information in sequence, and scroll through it with the ZERO key
(ahead) or the TARE key (backwards):
· "ch. x", in which x is the scale number (always 1).
· " um yy" in which yy is the unit of measure (kg, g, t o lb).
· gross weight (for about a second the message "GroSS" appears and then the gross weight value).
· Tare weight (for about a second the message "tArE" appears or "tArEpt" if it is a manual tare; then the tare value
appears).
- Press C to return to weighing.
NOTES:
- If the alibi memory is empty, when the MODE key is pressed the message “EMPTY” appears for about a second, an
error acoustic signal is enabled and one returns to weighing.
- If the entered ID is not valid, in other words, if there is no stored weigh relative to the entered ID, the message " no id"
appears and an error acoustic signal is enabled and one returns to weighing.
INITIALISATION OF THE ALIBI MEMORY
It is possible to cancel all the weighs made, initialising the alibi memory; this operation can be made directly on the
indicator (see the parameter “SETUP” >> “ini.AL” of the set-up environment, TECH.MAN.REF.) or through the serial
command (see “SERIAL COMMANDS” below).
NOTES:
- It is not possible to just cancel a single weigh.
The initialisation is possible only with a non approved instrument.

cancellation
18.8 DISPLAY WITH SENSITIVITY X 10 (VISS) (TO BE USED IN TESTING DURING THE
CALIBRATION)
By pressing the MODE key one switches from the weight display with normal sensitivity to a sensitivity ten times greater; in
fact, one will note that the last digit on the right of the display will have a sensitivity equal to the scale’s division divided by
10.
If a printout is carried out, the weight values are printed with the normal sensitivity.
TAKE NOTE: In case the instrument is LEGAL FOR TRADE, when “MODE” is pressed, the sensitivity times 10 is displayed
for five seconds after which the instrument returns to standard weight displaying.
18.9 HOLD: FREEZING THE WEIGHT ON THE DISPLAY (hLd)
By pressing MODE, the value of the weight is held on the display, and the display shows HoLd alternately with the weight
held value (every 5 sec). To release the weight value on the display, press MODE key again.
18.10 HORIZONTAL TOTALIZER (Sum of lots) (tot o)
TYPE OF TOTALISATION (NORMAL, FAST, AUTOMATIC)
Once the totalizer operating mode is selected, both horizontal and vertical, one is asked to set the type of totalization:
normal (t.norM), fast (t.FASt) or automatic (Auto); with ZERO or TARE one changes the parameter; with ENTER/PRINT
one confirms.
- In the normal totalisation, for each accumulation operation there is the display of the weigh number and the net weight
total, before the printing of the data.
- In the fast one, just the display of the "-tot-" message appears on the display, before the printing of the data.
- In the automatic one, there is the automatic acquisition of the stable weight; therefore the display of the "-tot-" message
on the display and then the printing of the data.
Max.tot: NUMBER OF CONSECUTIVE TOTALISATIONS AFTER WHICH THE TOTAL IS AUTOMATICALLY PRINTED
AND RESET
After having made the set weighs, the general accumulated total is printed and reset; set a value between 0 and 63.
NOTE: the value 0 disables the function
TOTALISATION OPERATIONS
In order to carry out the totalisation it is necessary to press the MODE key (if the automatic totalisation has not been set): if
the weight is accumulated in two total levels (a partial total and a general total).
To totalize, the net weight must be
- at least 1 division with non approved instrument and with normal or fast totalisation;
- at least 10 division with non approved instrument and with automatic totalisation;
- at least 20 divisions with approved instrument.
To avoid undesired accumulations, the "MODE" key is active just once; it reactivates depending on the setting of the “
rEACT ” parameter in the SET-UP environment, in other words, either after passing by the net zero of the scale, by
instability or always (see “REENABLING OF THE PRINTOUTS AND THE INDICATOR FUNCTIONS” section).
If the presence of a printer has been configured, the "MODE" key causes also the printing of the weight values.
By pressing the MODE key again, without having reenabled the totalisation:
After a totalisation, press the MODE key again:
- with the normal totalizer, one can temporarily view on the display the number of weighs carried out and the PARTIAL NET
TOTAL accumulated until that moment (Subtotal): if the accumulated digit is more than 5 digits the visualisation takes place
in two stages.
- with the fast totalizer the " no.0.UnS " error message is displayed.
33
TPWATEX
NOTE:
- If the gross or net weight is equal to zero, with the normal totalizer the indicator displays the accumulated total, while
with the fast totalisation the “LOW” error message is displayed.
TOTALISATION WITH PRINTING
If the presence of a printer has been configured, upon each pressing of MODE, one prints the data programmed in step
SEtuP >> SEriAL >> CoM.Prn >> Pr.ConF of the set-up environment (TECH.MAN.REF.), for example:
- Weigh number
- GROSS weight
- TARE weight
- NET weight
PRINTING AND ZEROING OF THE TOTALS
The instrument has two different total levels, a partial total and a general total, which increase upon each totalisation; these
may be printed and zeroed independently from each other.
To print and zero the PARTIAL TOTAL one should press for an instant the ENTER/PRINT key; depending on the type of
totalisation, various messages will be displayed:
- With normal totalisation the number of weighs and the accumulated total will be displayed.
- With fast or automatic totalisation the message “totAL” will be displayed.
The number of weighs made and the NET WEIGHT TOTAL is printed.
To print and zero the GENERAL TOTAL one should press for a few seconds the ENTER/PRINT key; depending on the type
of totalisation; various messages will be displayed:
- With normal totalisation the number of weighs and the accumulated total will be displayed.
- With fast or automatic totalisation the message “G.totAL” will be displayed.
The number of weighs made and the NET WEIGHT TOTAL is printed.
To view at any time the number of weighs and the accumulated net weight in the totals:
- By pressing for an instant the 6 key, the following will be displayed in this sequence:
"n x", in which x is the number of weighs made
"totAL", followed by the accumulated PARTIAL NET TOTAL.
-
By pressing in sequence the F and 6 keys, the following will be displayed in sequence:
"n x", in which x is the number of weighs made
"totAL", followed by the accumulated GENERAL NET TOTAL.
MEMORY STORAGES
It is possible to memorize the weigh totalisation in one of nine memory storages (identified from 1 to 9 ).
- Press in sequence the F and 5 keys; the display shows " rn n ":
- Enter the desired storage number (from 1 to 9).
- Now all the made totalisations are stored in the storage number just entered.
- To change the storage, repeat the same operations.
To recall or zero the PARTIAL TOTAL of a storage, it is necessary to recall first its identifying number, as previously
described; however the GRAND TOTAL is not available for each storage.
NOTE:
- The selected storage remains active for all the following totalizations until it is substituted with another.
- All the values accumulated in the single storage numbers are automatically zeroed each time the instrument is turned
off.
- When turned on, the indicator automatically goes to storage nr. 0 (not selectable).
Storage nr. 0 is considered to be the basic one in which non-addressed weights are accumulated.

18.11 VERTICAL TOTALIZER (Sum by recipe) (tot S)
Like the horizontal totaliser but with each pressing of MODE the indicated weight is totalised and automatically tared; in this
way it is possible for example to fill a container with various products.
18.12 COUNTING (Coun)
In this functioning mode it is possible to carry out the reference operations in order to use the scale for counting pieces.
When the functioning mode is selected, one is asked to set some parameters:
-
"uM.APW" : unit of measure of the average unit weight (APW).
· Press ENTER/PRINT to enter the step.
· With the ZERO or TARE keys select the unit of measure (g / kg / t / Lb).
· Confirm with ENTER/PRINT.
· Press many times the C key until the display shows the message “SAVE?”.
· Press ENTER/PRINT to confirm the changes made or another key to not save.
"WAit.t" : sampling interval.
Setting of the sampling time (in seconds, with a decimal); greater is the time set and more precise will the calculated
APW be.
· Press ENTER/PRINT to enter the step.
· Set the desired time.
· Confirm with ENTER/PRINT.
· Press many times the C key until the display shows the message “SAVE?”.
· Press ENTER/PRINT to confirm the changes made or another key to not save.
It is possible to change the sampling time also while weighing, by pressing the F and 7 keys. If the entered value is
confirmed, it substitutes the one in the set-up environment.
-
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 press the MODE button: the counting function activates
3) The display suggests a REFERENCE QUANTITY. The possible options are: 5, 10, 20, 30, 40, 50, 60, 75, 100, 200.
4) Press “ZERO” or “TARE” the number of times needed to reach the desired sample size.
5) Put the quantity of pieces chosen for the SAMPLE on the scale and press ENTER/PRINT to confirm or C to cancel the
operation and return to weighing.
6) Press ENTER/PRINT; the display will indicate SAMPL 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.
7) Add the rest of the items to count in the container and whose value will appear on the display.
8) Unload the scale, the APW will remain stored in memory for the next counting of similar pieces, without having to
repeat the REFERENCE operation.
9) By pressing the MODE key one switches from the display of the number of pieces to the display of the net weight and
vice versa.
10) To carry out a new reference operation, press at length the MODE key and repeat the operations as describe in
point 3).
NOTE: If the number of calculated pieces is greater than 999999, the display shows just the first 6 digits on the right.
PIECE COUNTING IN EXTRACTION
1) Load a FULL container on the scale and press "TARE" to tare it.
2) Press "MODE": The display suggests various REFERENCE QUANTITIES: 5,10,20,30,40,50,60,75,100,200
3) Press "ZERO" or "TARE" various times until the chosen quantity is displayed.
4) From the container take off the same number of pieces and press "ENTER/PRINT” to confirm. The display shows
"SAMPL" while the indicator calculates the Average Piece Weight. The display shows in negative the quantity extracted.
5) Continue the counting in extraction.

“Er.Mot” ERROR DUE TO WEIGHT INSTABILITY DURING THE SAMPLING
It may happen that during the sampling phase the weight is unstable and therefore it is not possible to correctly calculate
the APW. The “Er.Mot” is shown remaining for about three seconds. One should therefore repeat the sampling operation.
MINIMUM WEIGHT OF THE SAMPLE
It is advisable to use a reference quantity equal or greater than 0,1% of the scale capacity.
In any case, the weight of the reference quantity should not create an APW lower than the two internal points of the
converter (intrinsic limit of the instrument); if this condition takes place, during the sampling, the display will indicate for an
instant: "Error " and the quantity put on the plate will not be accepted. One should therefore use a higher reference
quantity.
VARIABLE SAMPLE SIZE (REFERENCE QUANTITY)
It is possible to insert directly by keyboard any reference quantity up to 999999 (not only the quantities proposed by the
MODE key).
- With the scale at zero, after having stored a tare, press “F”+ “5”; the display will indicate “n S" and then "0" or a
quantity already stored.
- Modify and/or enter the quantity (up to 999999) using the numeric keys.
- Follow the operations describe in point 5) in the COUNTING PROCEDURE section.
DISPLAY AND MODIFICATION OF THE AVERAGE PIECE WEIGHT
It is possible to view or enter a known Average Piece weight using the keyboard. This can significantly speed up the
reference operations.
- With the scale at zero, after having stored a tare, press “F” + “6”, or the ENTER/PRINT key at length.
- The display will indicate " APW “ and then "000.000" or a previously entered value expressed with three decimal digits
in the programmed unit of measure.
- Enter the APW value with the keyboard (or leave the one present) and press ENTER/PRINT to confirm.
Example:
Unit of measure of the APW in g
000.000 means 000,000 g (for example APW = 001,050 = 1,05 g).
Press ENTER to confirm and load the pieces to count as described in section PCS COUNTING point 5.
PRINTING UNDER COUNTING MODE
If the presence of a printer has been configured, each time ENTER/PRINT is pressed, while either weight or pieces are
displayed, one prints the data programmed in the SEtuP >> SEriAL >> CoM.Prn >> Pr.ConF of the set-up environment
(TECH.MAN.REF.); for example:
- GROSS weight
- TARE weight
- NET weight
- Quantity of PIECES (PCS) on the scale in that moment.
- calculated APW, expressed in the set unit of measure, with three decimal digits

Weight less than the minimum weight provided for the printing, the totalisation or the
transmission of the string, standard or extended, upon pressing of the print key.
Weight not passed by net 0 or by instability.
In standard mode, with approved instrument, one is trying to print while the instrument is
converting the unit of measure.
In the input/output mode (set as “in.out”), one is trying to acquire a second time the input
weight.
In the input/output mode (set as “in.out”), one is trying to acquire a second time the output
weight.
In the input/output mode (set as “G.t.” or “1st.2nd”), one is trying to acquire a second time the
input weight.
In the input/output mode (set as “G.t.” or “1st.2nd”), one is trying to acquire a second time the
output weight.
In the counting mode, the sampling has not been made because the weight is unstable.
In the counting mode, the sampling has not been made because one should use a higher
reference quantity.
It is displayed when data is stored in the permanent storage of the instrument (setpoint, tares,
ticket progressive, etc.)
