15. BASIC FUNCTIONS
15.1 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.
15.2 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.
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
numeric 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.
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 greater
than 2 divisions and stable.
It is possible to carry out the selection also during the weighing if the tare has not been disabled, by pressing 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.
To disable the type of tare:
- Turn on the indicator, press the TARE while the firmware version is displayed (the display shows the “typE”
menu).
- Press ZERO many times (to scroll ahead through the parameters) or TARE (to scroll backwards) until one finds
the “FModE” parameter.
- 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 “tArE t” parameter.
- Press ENTER/PRINT to enter the parameter.
- With the ZERO or TARE keys select the diSAb (disabled tare) parameter.
- Confirm with ENTER/PRINT.
- Press the C key many times until the display shows the message “SAVE?”.
- Press ENTER/PRINT to confirm the changes made or another key for not saving.
The indicator stores the last selection made, also after it is turned off.

TPWATEX3GD
15.3 LIMITATION OF THE TARE FUNCTIONS
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
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.
- It’s possible to cancel the tare value only with an UNLOADED
scale
≥ 100kg
With approved instrument, the d.SALE step is not displayed.
15.4 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 (the display shows the “typE”
menu).
- Press ZERO many times (to scroll ahead through the parameters) or TARE (to scroll backwards) until one finds
the “FModE” parameter.
- 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 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.
15.5 BATTERY LEVEL WARNING
The indicator is able to recognize whether it is powered from the mains or through a battery
If the indicator has the LCD display 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 indicator to the mains for the recharging. Furthermore, for a few seconds
the "Low.bat " message appears on the display (voltage under 5,9 V).
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 5,8V.
- It’’s possible to view the recharge percentile of the battery by pressing the ZERO key upon start-up (see section 12
– “TURNING ON AND OFF”).
22
TPWATEX3GD
15.6 "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.
See the electrical connection scheme (TECH.MAN.REF.) for the connection of the device.
15.7 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: 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 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.
- The selection of the range number with multirange functioning is made during the indicator’s calibration
(TECH.MAN.REF.).
15.8 DATE/TIME ADJUSTMENT (OPTIONAL)
The indicator can be fitted with the date/time option; in this case, the “CLoCK” message is shown when instrument is
turned on. To set the date/time follow the procedure below:
- Press in sequence the F and 8 keys: in this order one will be asked to enter the day, month, year, hour, and
minutes. The entry of each parameter must be confirmed with ENTER/PRINT.
- Press the C key many times until the message “SAVE?” appears on the display.
- Press ENTER/PRINT to confirm the changes made or another key to not save.
- The “CLoCK” parameter is not displayed if there is no date/time option.
15.9 “SCREEN SAVER” FUNCTION (OPTIONAL)
If the indicator is fitted with the date/time function, it is possible to enable the “Screen Saver”: after a programmable
time (from 1 to 255 minutes) with the scale unloaded, the time is shown on the display, in the “HH:MM:SS” format
and the clock symbol ( ) is enabled. As soon as a weight variation is detected, or a key is pressed, the indicator
returns to viewing the current weight.
To set the function:
- Turn on the scale, press the TARE key while the firmware version is displayed (the display shows the “typE”
menu).
- Press ZERO many times (to scroll ahead through the parameters) or TARE (to scroll backwards) until one finds
the “FModE” parameter.
- Press ENTER/PRINT to enter the menu.
- Press ZERO many times (to scroll forwards through the parameters) or TARE (to scroll backwards) to find the
“SCr.SAV” parameter.
- Press ENTER/PRINT to enter the parameter.
- With the ZERO or TARE key select the possible options: “no” (disabled), “YES” (enabled).
- Confirm with ENTER/PRINT; if one has selected “YES”, one is asked to enter the number of minutes after which
the indicator should show the time: enter a number between 1 and 255 and confirm with ENTER/PRINT.
- Press the C key many times until the display shows the message “SAVE?”.
- Press ENTER/PRINT to confirm the changes made or another key to not save.
NOTE: the “SCr.SAV” parameter is not shown if there is no date/time option.

TPWATEX3GD
15.10 REENABLING 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 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 (the display shows the “typE”
menu).
- Press ZERO many times (to scroll ahead through the parameters) or TARE (to scroll backwards) until one finds
the “FModE” parameter.
- 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.
15.11 STORED TARE MEMORY VALUES
It’s possible to store up to 30 tare memory values, identified by the location numbers 1 to 30, 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 "t nn". in which nn is the storage number to be
entered. For example, by pressing “01” and ENTER/PRINT the display will indicate "t00000" or any value that
already exists in the tare memory location "01".
- 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 off.
RECALLING STORED TARE VALUES
To recall a stored value:
- Press the keys “F” + “1” in sequence. The display will indicate "t nn" in which nn is the storage number to be
entered.
- Press the keys corresponding to the desired tare value location in memory (01-30) and ENTER/PRINT: the tare
will be enabled.
15.12 KEYBOARD LOCK
It is possible to disable the keyboard functions in order to avoid accidental pressing of the keys:
- Press in sequence the F and 0 keys: the display shows “LoC.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 (also
in the 5-key indicator): refer to the “inPutS" parameter of the set-up environment (TECH.MAN.REF.); in this case
however when the keys are enabled or disabled,, the message “LoCkEd” does not appear on the display and upon
pressing a key the display shows “LoCkin” for an instant.

one will be asked to select one or more operating parameter; refer to the specific functioning mode section for the
relative description.
- The instrument automatically goes to the following step.
- 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.
16.1 UNIT OF MEASURE / POUNDS CONVERSION (Std)
By pressing "MODE" key the weight conversion between the scale unit of measure and lb is made and vice versa.
NOTES:
- The conversion takes 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 goes to the
scale unit of measure.
16.2 NET/GROSS SWITCH (ntgS)
If a tare is set by pressing the MODE key, for about 3 second interval, the gross weight is displayed.
16.3 SET POINT ON THE GROSS WEIGHT (StPG)
By selecting this functioning mode, in the normal scale status, one enables the function of the outputs on the GROSS
weight; with the optional boards, 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 for each output
used: none, with hysteresis (enabling and disabling set point) 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
25
TPWATEX3GD
(direct or weight stability).
MODE WITH HYSTERESIS
One enters two SET POINTS for each output: a DISABLING one, which, when the gross weight is lower than it, it
disables the concerned output; and an ENABLING one, which, when the gross weight is equal or greater than it, it
enables the concerned output.
By keeping the ENTER/PRINT key pressed for about 3 seconds one enters the DISABLING and ENABLING SET
POINT values, only for the configured outputs:
– The display shows " S1 oF " (DISABLING output 1 SET POINT): press ENTER/PRINT to enter the Step.
– Use the MODE key to choose the digit to be increased (BLINKING DIGIT), the scrolling of the digits goes from
left to right.
– Decrease or increase the value using the ZERO or TARE keys.
– When finished entering the values, confirm with ENTER/PRINT.
– The display shows " S1 on " (ENABLING output 1 SET POINT): enter the weight value like in the preceding SET
POINT and confirm with ENTER/PRINT.
– With the C key, one quickly zeros the set point value.
– In the same way go ahead with the "Sb2.oF", “Sb2.on”, “Sb3.oF”, “Sb3.on”, “Sb4.oF”, “Sb4.on” (if present).
– Once finished the programming of the set points, one should exit with the C key to return to weighing.

NOTES
- If the relay functioning mode has not been configured, the prolonged pressure of the ENTER/PRINT key has no
effect.
- The DISABLING SET POINT must be equal or less than the ENABLING one;
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 and the anomaly is indicated through the
“ModiFY” message at the exit of the configuration MENU of the SET POINTS.
- If in the ENABLING SET POINT one enters a value lower than the DISABLING one, the instrument does not
allow to confirm.
- 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.
- The 0 value is valid for the enabling and the disabling set points and just the set points greater or equal to zero
are accepted.
- The check of the weight remains active on the present value even during the modification of the SET POINT,
until the new value is confirmed.
- At start-up, the relays are managed from when the weight is displayed and these take on the configuration set in
the set-up environment. These are not managed inside the technical set-up.
The tare operations are active.
MODE WITHOUT HYSTERESIS
It is the same as the functioning mode with hysteresis, except that one enters just one SET POINT value (therefore
the enabling threshold coincides with the disabling threshold).
16.4 SET POINT ON THE NET WEIGHT (StPn)
By selecting this functioning mode, in the normal scale status, one enables the function of the outputs on the NET
weight; the entry of the SET POINTS and the functioning notes are the same as the gross weight mode.
26
TPWATEX3GD
16.5 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.
Once the in/out mode has been selected, the message “tyPE” is shown and one is asked to select with
ENTER/PRINT the totalizing mode:
- 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 key 1 of the indicator), one acquires the first weight, on the display is shown “ - - 1 - - -“ accompanied by a
prolonged beep;
- Press key 2 of the indicator), 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 section 15.10
“REENABLING OF THE INDICATOR FUNCTIONS”.
It is possible to interrupt the weighing cycle by pressing the C 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.
NOTES:
- The 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 section 15.10 “REENABLING OF THE INDICATOR FUNCTIONS”.
- The tare operations are DISABLED.
16.6 MULTISCALE REPEATER (MAStr)
The system is made up of one or more indicators (up to 4, called SLAVES), connected to one or more weighing
system, which communicate with another indicator (called MASTER) which acts as weight repeater, on which it is
possible to view the weight of each single scale or the sum of the weight detected by the single scales.
In the MASTER, by selecting with ENTER/PRINT in this operating mode, one is asked to enter the number of the
SLAVES which one wants to use: for an instant “nuMSL” is displayed; then, one enters the number (between 01 and
04).
In the SLAVES, instead, one needs to set a different functioning mode than the “MAStr” and enter a code (between
01 and 04, to identify each single SLAVE) in SEtuP >> SeriAL >> CoMPC >> PCModE >> 485 (see set-up
environment, TECH.MAN.REF.).
27
TPWATEX3GD
NOTES:
The SLAVE indicators must be of the same model as the MASTER indicator.
FUNCTIONING
When turned on, the MASTER predisposes itself for the connection to the SLAVES present (“ECo n” message
appears, in which n is the SLAVE number which is to be detected): when at least one SLAVE is detected, it positions
itself on the one with the lowest 485 address.
By pressing the MODE key various times:
- if just one slave is configured this is repeated also on the active slave in that moment;
- if various slaves are configured one goes from SLAVE to SLAVE, ordered by 485 addresses: the display
shows “SCA n” (in which n is the SLAVE number); after this, the weight transmitted by the selected SLAVE is
displayed. In this mode, about every 10 seconds, the message “SCA n” appears, indicating the meaning of
the shown data and in which n is the number of the active scale in that moment.
By pressing the ZERO, TARE and ENTER/PRINT keys on the MASTER, these are repeated also on the active
SLAVE in that moment.
Every 10 seconds, the message “SCA n” appears, indicating the meaning of the shown data and in which n is
the number of the active scale in that moment.
To view the sum of weights present on all the scales, keep the MODE key pressed for a few seconds: the
display shows “SUM” and then the sum of the net weight present on the scales.
In the display of the sum:
- the “SUM” message appears about every 10 seconds and it indicates that the sum of the weights present on
the scales is being displayed
- The reference unit of measure is that of the connected SLAVE with the lowest address; if the other weights
have different units of measure, these are automatically converted.
- If the sum of the weights is greater than 999999, the segments in the upper part of the display are turned on.
- If the sum of the weights is less than -99999, the segments in the lower part of the display are turned on.
- If the sum of weights is not valid (because one or more slaves is in underload or overload), the segments in
the central part of the display are turned on.
Furthermore by pressing the numeric keys:
- if just one slave is configured this is repeated also on the active slave in that moment;
- if various slaves are configured, it is possible to directly select the number of the desired SLAVE through the
relative numeric key of the keyboard (I.E.: MASTER press the 1 key selection of SLAVE 1).
KEY
SLAVE
Select slave 1
Select slave 2
Select slave 3
Select slave 4
WARNING:
- To carry out the weight repeater function it is sufficient that just one SLAVE instrument in the system be turned
on. When turned on, the MASTER places itself automatically on the first turned on SLAVE (lowest 485 address);
if all the instruments are off or if the radio signal does not reach the MASTER, on the same display the “ECo n”
message is displayed in which n is the address number of the SLAVE with which one is trying to communicate.
- If there are various slaves, in no case is it possible to transmit the functionality of the MODE key and the numeric
keys to the active slave.
- To carry out the sum function, it is necessary to have a connection with at least two SLAVES.
- In the sum mode, it isn’t possible to transmit the functionality of the ZERO, TARE, ENTER/ PRINT and C keys to
28
TPWATEX3GD
-
the SLAVES.
If the connection is lost with the SLAVE which is acting as a repeater, the MASTER will try to reconnect it; if after
about a second this does not happen, it connects with the following SLAVE.
If the connection is lost with the SLAVE in the sum mode, the MASTER tries to reconnect it: if this happens, it
remains in the sum mode, otherwise it passes to the repeater mode of the following SLAVE.
If the automatic switch off has been enabled in the MASTER, after about 5 minutes that one is connecting with
the SLAVES (in other words the ECo-n message appears on the display), it turns off.
By pressing the C key at length, this is repeated on the active slave; to turn off the master indicator one should
make sure that one is in the slave detection phase (“ECo n” appears on the LED display, in which “n” is the
number of the SLAVE which one is trying to detect)
16.7 ALIBI MEMORY (ALibi) (OPTIONAL)
The alibi memory allows to file 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 storage of a weigh in the alibi memory is possible only if the weight is stable; (it can not be in underload or in
overload) and the gross must be equal or greater than zero. In case these conditions are not respected:
_in the response to the PID serial command there will be “NO” instead of the ID;
_there is no transmission in the case that the ENTER/PRINT key is pressed.
When one presses the ENTER/PRINT key, the weight and the ID is transmitted and the display shows the "tr.id"
message for about 2 seconds.
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.
Therefore the weigh relative to an ID may be verified just if:
- it has a rewriting number equal to the current one of the alibi memory and a weighing number equal or less than
the last value received with the “PID” command;
- it has a rewriting number equal or greater than zero, but less than 1, in comparison to the current value of the
alibi memory, and a weigh number greater than the last value received with the “PID” command.
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),
if the gross weight is equal or greater than zero and without the TILT alarm (see paragraph 15.6).
The storage of the weigh by pressing a key is possible only if the function is active (or passage from 0 or weight
instability, or always depending on how the F.ModE >> rEAct step has been configured in the technical set-up,
TECH.MAN.REF., and minimum weight of 20 divisions with approved instrument,).
If these conditions are not respected:
29
TPWATEX3GD
- in the response to the PID serial command one has "NO" in the place of the ID.
- there is no transmission if 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:
- 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:
- The alibi memory can store up to 131072 weighs; then the rewriting takes place from the beginning.
- 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.
SERIAL COMMANDS
Besides the commands described in the “11.4 FORMAT OF THE SERIAL COMMANDS”, TECH.MAN.REF., in this
functioning mode also the commands below are available:

NOTE: During the cancellation, the display shows “WAit” and all the indicator functions are “frozen”.
The commands are ignored if one is not in the alibi memory functioning mode.
16.8 +/- TOLERANCE CHECK (ChECK)
In this functioning mode, the instrument commands the functioning of the SP1, SP2, SP3 and SP4 icons of the LCD
display and the functioning of the 4 relais of the 2 expansion boards (optionals), on the basis of a freely programmed
TARGET WEIGHT, a LOWER TOLERANCE value, an UPPER TOLERANCE value, and an ENABLING threshold.
--------------(thrESh)--------------(t.Min)--------------TARGET WEIGHT--------------(t.MAX)---------------------------------It is possible to carry out a check on the gross weight or the net weight: in the TECHNICAL set-up, after the selection
of the Check mode, one is asked to select “GroSS” (gross weight) or “nEt” (net weight). The selection of the check
type (net or gross), causes the configuration of the relay’s relative default parameters.
By setting the threshold for activating the functioning mode, if the weight is under the set threshold, no check on the
weight is made; if instead the weight reaches or surpasses the threshold, the check on the tolerances is enabled.
ENTERING THE ACTIVATION THRESHOLD, TARGET AND THE TOLERANCES
-
-
-
-
-
Press the MODE key; the instrument first shows “tArGEt“ then “000000” or the target previously used. With the
keyboard enter the desired target; with C one quickly zeros the entered value; by pressing C again one cancels
the entry and returns to weighing.
Confirm with ENTER/PRINT: the display shows first “t.Min” then “000000” or the T1 lower tolerance previously
used. With the keyboard enter the desired lower tolerance; with C one quickly zeros the entered value; by
pressing C again one cancels the entry and returns to weighing.
Confirm with ENTER/PRINT: the display shows first “t.MAX” then “000000” or the T1 upper tolerance previously
used. With the keyboard enter the desired upper tolerance; with C one quickly zeros the entered value; by
pressing C again one cancels the entry and returns to weighing.
Confirm with ENTER/PRINT: the display shows first “thrESh” and then “000000” or the enabling threshold used
previously. Through the keyboard enter the desired enabling threshold; by pressing C one quickly clears the
entered value, while by pressing again C one cancels the entry and returns to the weighing mode.
Confirm with ENTER/PRINT: the display shows “StorE” for an instant; after this it returns to weighing.
NOTE: If the entered value is wrong (i.e. tolerance value greater than the target or target greater than the scale
capacity) the indicator emits a prolonged sound and zeros the entered value; furthermore, if a value different than the
scale division is entered, it is rounded off to the nearest minimum division multiple.
PROCEDURE
After having entered the activation threshold, the target and the tolerance values, put the weight on the scale: if the
target is greater than 0, the display shows, at regular intervals, if the weight is within the entered tolerances:
Scale
Weight < Target - t.Min
Target - t.Min ≤ Weight ≤ Target + t.MAX
Weight > Target + t.MAX
Weight ≥ t.Min

TECHNICAL NOTES
- The 0 value is valid for the tolerances and for the activation threshold as well.
- By setting the target at 0 the weight check is disabled.
- The check of the weight is active also during the modification of the target and the tolerances, according to the
last confirmed values. The new entered values start working after having been confirmed.
- The 4 relays of the 2 expansion boards (optional) are automatically enabled depending on the mode selection ,
and may be used to manage external signals which show the operator whether the weight on the scale is
INSUFFICIENT, CORRECT, ABUNDANT in comparison to the TARGET WEIGHT. Furthermore it is not possible
to set the functioning mode of the relays, but just the status (NO / NC) and the type of check (direct or upon
stability).
- It is possible to set the target, the tolerances and the activation threshold through the serial line, see “Serial
command format”, TECH.MAN.REF.
16.9 SAMPLE WEIGHT PERCENTAGE (3.PErC.)
In this operating mode, the instrument shows on the display the net weight expressed as a percentage, comparing it
with a reference weight which has been previously linked to a percentage.
When the functioning mode is selected, one is asked to set of:
-
"WAit.t" : sampling interval.
Setting of the sampling time (in seconds, with a decimal); greater is the time set and more precise will the
sampling be.
• Set the desired time.
• Confirm with ENTER/PRINT.
• Press many times the C key until the display shows the message “SAVE?”.
With the indicator fitted of a 17-key keyboard, by pressing the F and 7 keys, it’s possible to change the sampling
time also in the weighing mode. If the entered value is confirmed, it will substitute the one in the set-up
environment.
PROCEDURE
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 MODE.
3) The display suggests a percentage; the possible options are: 100.0, 200.0, 5.0, 10.0, 20.0, 30.0, 40.0, 50.0, 60.0,
75.0.
4) Press “ZERO” or “TARE” several times to reach the desired sample size.
5) Put the reference weight 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 show “SAMPL”. After a few instants the display will show the percentage
selected put on the platform.
7) Add the quantity to be measured on the scale and the value will appear on the display.
8) By pressing the MODE key one switches from the display of the percentage to the display of the net weight and
vice versa.
9) To carry out a new sampling, press at length the MODE key and repeat the operations as describe in point 3).
“Er.Mot” ERROR DUE TO WEIGHT INSTABILITY DURING THE SAMPLING
It may happen that during the sampling phase the weight is unstable; the “Er.Mot” is shown remaining for about three
seconds. One should therefore repeat the sampling operation.
MINIMUM WEIGHT OF THE SAMPLE
It is necessary to use a net weight greater than 0.
33
TPWATEX3GD
VARIABLE PERCENTAGE QUANTITY (only for 17-key indicator)
It is possible to insert directly by keyboard any percentage, different from the ones 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 (max 3000.0) using the numeric keys.
- Follow the operations describe in point 5) in the PROCEDURE section.
16.10 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.
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. Furthermore, if the direct
sales has been configured in the SEtup >> dSALE parameter, TECH.MAN.REF, this displaying is possible only with
if the capacity is equal or less than 100 kg (220 lb).
16.11 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.
16.12 PEAK WEIGHT PEAKS DETECTION (PEaK)
It is possible to use the instrument to store the maximum weight value measured during the weigh (PEAK), useful to
measure, for example, the breaking load of the materials.
By pressing the MODE key, the peak mode is enabled; on the LED display the maximum weight reached will be
displayed, alternated with the message PEAK every 5 sec.
The test terminates by pressing the MODE key again or when the weight peak surpasses the maximum capacity of
the instrument (for an instant PEAk.oF is displayed and the indicator returns to standard operation)
SETTING SAMPLING TIME
It is possible to set the minimum time period of the peak impulse beyond which the measuring is accepted. This time
is set by keeping “ENTER/PRINT” pressed for a few seconds when the indicator is not in the peak mode: the
message -tP- appears on the display followed by a number which corresponds to the minimum time length of the
impulse expressed in hundredths of seconds.
By pressing “ZERO” or “TARE” the following settable values are proposed: 1, 2, 3, 4, 5, 10, 20, 50, 100 and 127;
press “ENTER/PRINT” to confirm the desired value, (the indicator will return to weighing).
The default value is 2.

16.13 HORIZONTAL TOTALIZER (Sum of lots) (tot 0)
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.
- In the fast one, just the display of the "-tot-" message appears on the display.
- In the automatic one, there is the automatic acquisition of the stable weight; therefore the display of the "-tot-"
message on the display.
MAx.tot: NUMBER OF CONSECUTIVE TOTALISATIONS AFTER WHICH THE TOTAL IS AUTOMATICALLY
RESET
After having carried out the set weighs, the accumulated general total is 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 to load the weight on the scale and 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 section 15.10 “REENABLING OF THE INDICATOR FUNCTIONS”).
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.
NOTE:
- If the gross or net weight is less or equal to zero, by pressing the MODE key the display shows the “LoW” error
message.
- If the indicator is in the under load or over load status, by pressing the MODE key the display shows the
“un.oVEr” error message.
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 zeroed independently from each other.
To 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.
To 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.
During the weighing, it is possible to view at any time the number of weighs and the accumulated net weight in the
35
TPWATEX3GD
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.
16.14 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.
Note: At the end of the totalisation operations, if one wants to view the gross weight on the scale one should press
the C key.
16.15 PIECE 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.
Independently from the unit of measure selected, the APW has always three fixed decimals.
-
"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 during the weighing, by pressing in sequence the F and 7 keys. If the
entered value is confirmed, it substitutes the one in the set-up environment.
36
TPWATEX3GD
COUNTING PROCEDURE
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.
6) 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:
37
TPWATEX3GD
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.

DESCRIPTION
The scale is zeroing the weight.
It is displayed when one selects the alibi memory functioning mode, and upon start-up, the alibi memory is
not connected or there are communication problems between the indicator and the board. The “unit of
measure/pounds conversion” functioning is automatically set, but not saved in the set-up environment.
A function has been linked to input X (from 1 to 4) and this is not present; see the “InPutS” parameter of
the set-up environment (TECH.MAN.REF.).
In a set point functioning mode the output X has been set (from 1 to 4) and this is not present; see the
“outPut” parameter of the set-up environment (TECH.MAN.REF).
Print under way (PRN serial port is occupied) or indicator waiting to transmit a printing to a PC.
One is trying to print with an unstable weight.
One is trying to print with the weight in underload or in overload, in other words, with a weight of 9
divisions greater than the capacity or of 20 divisions below the gross zero.
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.
Unstable weight.
In the counting mode, the sampling has not been made because one should use a higher reference
quantity.
