1. Introduction
The CAT 27 scales series belong to a group of calculating electronic scales with the strain gauge
force transducer and digital readout of results. The family consists of four types of scales:
NEPTUN 2, SATURN 2, VEGA 2 and PLUTON 2. Various types are available in versions with
different measurement specifications: as the single interval, double interval or double range scale
with monochrome LCD or TFT color displays.
The CAT 27 scales are dedicated to work with the POS system consisting of a cash register or
computer and one or more scales connected in the scales system. Significant software flexibility
and a wide range of solutions make them applicable in small, medium and large retail outlets. The
main application of the various types of scales is as follows:
NEPTUN 2: the scale is designed for installation in the advanced barcode scanners. It is
offered in the form of ready to built weighing module with a remote display installed on a
rotating column of adjustable height and swivel head, as well as a part of a set containing
the most popular bi-optical scanners.
SATURN 2: the scale is intended for mounting in the cashier desk or box and any
horizontal barcode scanner can be installed inside it. The scale is equipped with a remote
display installed on a rotating column with adjustable height and swivel head.
VEGA 2: design of the measuring platform makes the scale applicable as a stand-alone or
mounted in the cashier desk or box. The scale is equipped with a remote display installed on
a rotating column of adjustable height and swivel head.
PLUTON 2: the stand-alone scale with built-in display and the ability to connect an
additional remote display on a rotating column with adjustable height and swivel head. It is
implemented mainly as a weight checker but using the remote display it allows to use this
scale for sales.
Scales’ features:
weighing articles
weighing and subtracting the tare
automatic switching off the tare after articles are weighted and the tare is taken out
automatic zero tracking (maintaining zero while unloaded)
inputting the unit price through the communication interface and calculation of the amount
to pay of weighted articles
inputting the name of weighted articles through the communication interface
3-button keyboard
graphical monochrome or color display showing the weight, unit price, the total amount, the
article name, messages for the user as well as ZERO, STABILITY, NET and FIXED TARA
indicators.
ability to connect two displays: the main and the additional one
available single interval (d=e=5g), double interval (d1=e1=2g, d2=e2=5g) or double range
(range I: d1=e1=2g, range II: d2=e2=5g) models of scales
communication with external devices (cash register, computer) through the RS232 interface

The display of the scale features two working modes:
Calculating mode displays weight, unit price, amount and article name
Non calculating mode displays weight and article name
Selection of the display mode is automatic and depends on whether the unit price will be sent to
the scale. After turning on the scale, the non-calculating mode is enabled (showing only the
weight), after the first transfer of the unit price the mode switches to a calculating mode which
remains active until powering off the scale. If only the article weight is displayed the scale
transmits zero as a unit price and amount.
There may be displayed the following indicators:

3. Technical conditions of installation and operation of the scale
3.1. Installation of the scale
Depending on the type of the scale it should be mounted on a cashier desk or in a cashier
box in the following way:
the NEPTUN 2 scale and a bi-optical scanner should be built into the cashier desk or box
in the way that the platter of the upper surface of the scanner is leveled with the surface
of the cashier counter.
the SATURN 2 scale in a basket should be built into the cashier desk or box in the way
that the platter of the scale is leveled with the surface of the cashier counter. Then the
horizontal barcode scanner should be put into the basket and secured from slipping by
attached self-adhesive Velcro tape. Make sure that the scanner does not touch beams of
the scale,
the VEGA 2 scale built into the cashier desk or box should be installed in similar way as
the SATURN 2 scale,
the VEGA 2 and PLUTON 2 stand-alone scales should be placed on a stable and leveled
surface.
The scale should be leveled so that the air bubble level indicator is in the center of the circle
drawn on the indicator. Level the scale with adjustable legs. After having leveled the scale
check for stability (all legs touch the ground) and whether the platter is correctly placed.
When the scale is working with a remote display it should be mounted on the cashier desk
or box in the way allowing to see it by the cashier and a customer. Then connect the
display to the scale’s platform. If necessary use separate the display for the cashier and
another one for a customer.
Connect the RS 232 scale interface cable with a PC or a cash register. Do not connect or
disconnect the RS 232 interface while using the scale as this may damage the interface.
Connect the external power supplier to the scale. It should be connected to the 230V
socket. During the subsequent operations take care of the power cable. In case of any
damage of this cable immediately disconnect the scale from the power supply and
contact the Service Center. It is recommended to use the separate power line for scales
and other electronic devices like cash registers, computers, etc. Connecting the scales to the
power line with other connected devices e.g. containing engines, can cause their
interference with the working scales and can damage the interfaces of scales.
3.2. Environment
The scale can be operated at temperatures from -10 to +40 ºC and humidity up to 85% in
an atmosphere free from corrosive substances. After a sudden change in temperature by
more than 5 ºC the scale should acclimate for 2 hours before connecting the power supply
(e.g. putting the scale into warm room after having transported it in the cold). Do not allow
the forming of condensation. When working in areas with higher humidity, but within the
limits stated above, it is advisable to turn off the power for 24 hours.
The scale may not be subject to shocks and vibrations, can’t work near sources of strong
electromagnetic fields, can’t be exposed to strong sunlight for long periods and can’t work
in the direct stream of air or in dusty areas.

3.3. Other operating remarks
During turning on the power the platter should be empty. After turning the power on the
scale automatically runs its test and resets by taking as a zero the actual scale load.
During the test, the display shows the version of the program, all indicators light up and the
digits change from 0 to 9. After completing the test displayed data shows zero and the
and indicators light.
If during subsequent operations of the scale the weight indicator will be different from zero
it is needed to reset the scale with the empty platter:
by pressing the key (for small deviations) or
by turning off and on the power supply of the scale or
by executing the scale reset from the main menu.
Avoid overloading or sudden load shocks of the platter. They can cause damage to the
transducer.
It is recommended to check the correctness of weight readings of the scale using a standard
weight of at least 1/3 of the scale’s range. If you notice that the errors are larger than the
limits are the scale should be immediately withdrawn from use and it is needed to contact
the service point.
It is especially important to review the readings of weight after having transported and
installed the scale, before starting using it. Foreign objects should not touch the platter.
The whole scale must be kept clean, not only for hygienic and aesthetic reasons but also for
measuring. Take care mainly of cleaning the platter and the space under the platter because
the gathered crumbs of weighted goods may impede the free movement of the platter, as
well as affect the functionality of the transmitter. The housing can be wiped with a damp
cloth. Too much water should not be used during the cleaning, which could pour into the
interior of housing.
Note: Failure to comply with technical installation and operation conditions specified in this
user’s manual releases the manufacturer from any liability of an inappropriate
functioning of the scale.
4. Operation
4.1. Turning on
After turning on the scale the internal test procedure runs for about 15 seconds checking the
individual scale components and thermal stabilization of the measuring circuit. During the test all
boxes of the display show consecutive digits and all indicators are lit. For precise zeroing the scale
any objects should not be put on the platter during the test and the platter shouldn’t be touched. If
the stability of the scale will be disrupted the scale will wait for stabilizing the load. After
successful completion of the test the display should show:
0.000
kg

User Manual CAT 27 scales series
ELZAB S.A.
4.2. Weighing
The articles should be gently placed near to the central point of the platter. Proceed to load the
scale evenly and without shocks or jolts. Negative readings below 20 units are signalized by
displaying> MIN < and the W5:UNDERLOAD message.
When the maximum load is exceeded by 9 x d=e intervals a message is indicated by displaying
the> MAX <and the W4:OVERLOAD. Maximum load is automatically reduced by the tare value if
it turned on earlier.
Note: Do not overload the scale above the maximum capacity. Overloading can cause
damage to the scale and void the warranty.
After loading the scale the display shows the weight value. When the scale is working
in calculating mode and the unit price was entered the display shows also the amount to pay:
Calculating mode
Non-calculating mode
RED APPLES
PEARS

3.220
3.220
kg
6.12
After weighing the commodity, understood as the stabilization of the positive result, and removing
the load from the platter the scale will automatically reset the unit price and delete the product
name from the display if they were previously inputted.
4.3. Zero setting
The scale features the indicator signalizing that the scale is not loaded. The indicator is lit if
the current platter load is less than ¼ of e1 unit.
Initial zero setting when turning on the scale
After turning on the scale and running the display test the scale will be automatically set to zero.
The display will show only zero values and the indicator will be lit. Initial zero setting
procedure will succeed if the weighing result during zeroing is stable and is in the range ± 10% of
the weighing range of the zero stored during the calibration of the scale.
In case of exceeding zero range the W1:INITIATING ERROR message will be displayed.
The scale is locked until removing the load exceeding the acceptable range.
Zero setting with the use of the key
Zeroing is possible in the range no greater than ± 2% of the maximum scale readings in relation to
the zero stored during turning on the scale (so-called "initial zero"). To reset the scale press
the key. The scale will be reset if the two conditions are met:
-current indication is within the range no greater than ± 2% in relation to the load stored just
after turning on the scale,
-indication of the scale will achieve stability within 5 seconds after pressing the key.
In case of exceeding the zeroing range the W2:ERROR RESET is displayed and the scale does not
reset. In case of instability the zeroing is not effected and the W3:SCALE UNSTABILE error is
displayed.

ELZAB S.A.
User Manual CAT 27 scales series
11
Automatic zero setting for negative readings
Procedure will succeed automatically if during several seconds the scale readings are negative or
the scale is under loaded. Other terms and conditions of automatic zero setting are the same as for
the zero setting with the use of the key.
Zero maintaining i.e. „zero tracking”
This feature prevents from "sliding" of the scale’s zero resulting from various external factors that
may affect the zero indication. It consists of an automatic zeroing when the platter is unloaded.
Other terms and conditions of zero tracking are the same as for the zero setting with the use of the
key.
4.4. Taring
The scale features the tare subtracting function (subtracting the tare reduces the weighing range by the
tare value). Activity of this function is signalized by indicator.
To activate the function press the key. If the scale is stable or will achieve stability within
1 second the current platter load will be considered as the platter weight. In case of instability the taring
is not effected and the W3:SCALE UNSTABILE error is displayed.
The maximum tare value depends on the type of scale and is indicated in the Section 2.2.
Technical specifications of this manual.
Turning off the tare is effected after removing the load from the platter and pressing
the key or automatically after removing weighted articles. In order to turn off the tare
automatically there should be effected the process of weighing articles which takes place when the
load of the platter is stable and greater then the MINIMUM RESULT set in the USER MENU.
Example of weighing with taring:
–
the scale is set to zero, the and indicators are lit,
–
load the scale (e.g. with a basket),
–
the scale indicates 0.788 kg, press the key
–
the tare value is inputted,the scale indicates 0.000 kgand the and indicators are lit,
–
remove the load (a basket),
–
the scale indicates -0.788 kg, the ,and indicators are lit,
–
put again the load on the platter (basket + its content),
–
the scale indicates 0.506 kg, the result is stable, the and indicators are lit,
–
read or transmit the result of weighing, press the key,
–
remove the load,
–
tare will be switched off automatically,
–
the scale indicates 0.000 kg, the and indicators are lit.
The scale enables setting the fixed tare value which is signalized by the lit indicator.
Turn on the tare by pressing another time the key while inputting the tare value or by single
pressing if the FIXED TARE setting in the USER MENU is active. It is possible to input several
tare values if the consecutive tare values are growing.

05 –PARITY CHECKING
Setting value
Meaning
01^
NO CHECKING
The parity checking means that bytes with the wrong parity
bit are discarded and the scale signalizes it by a beep.
02
CHECKING ENABLED
06 –STABILITY CONDITION
Setting value
Meaning
01
HIGHEST STABILITY
This parameter determines the criterion of the result stability.
If the criterion is not met the result of weighing is considered
as unstable. The smaller the number of this setting the
stringent the stability criterion. A stable result is an obligatory
condition for activation of main scale functions: zeroing,
taring, weighing and sending the measurement result. If after
loading the scale doesn’t send the result or send it with a few
seconds delay, the stability criterion should be broadened,
that is the number of setting should be increased.

08 –TRANSMISSION MODE
Setting value
Meaning
01^
AFTER PRESSING KEY
The result is sent by the scale only at the request of the
operator e.g. after pressing the key or by the request
through the interface.
02
AUTOMATIC STABLE
The result is automatically sent by the scale, just once, after
loading and stabilizing the indication. Before putting the article
on the platter the display should show and .
The result is sent only when the MINIMUM RESULT setting is
deferent from “00 x e”.
Example: the “MINIMUM RESULT” value was set at = 20 x e = 040 g
the load put on scale was 036 g -> the scale doesn’t send the result,
the load was increased to 042 g -> the scale sends the result.
03
AUTOMATIC CONTINUOUS
The scale sends the results continuously at 0.12 sec. time
intervals. The unstable results are not sent but the result
frame (containing the signs 0x20 in place of the digits) can
be sent if the “SENDING FRAME” for “STABLE AND
UNSTABLE” was set.

09 –SENDING MINUS
Setting value
Meaning
01^
ONLY POSITIVE
The negative result is considered as unstable and is
not sent.
02
POSITIVE & NEGATIVE
The negative result can be sent if it is stable.
10 –SENDING FRAME RESULT
Setting value
Meaning
01^
ONLY STABLE
The result frame is sent only when the result is stable.
02
STABLE & UNSTABLE
The result frame is sent after stabilizing the result or after the
time which is set in “STABILITY WAITING TIME.” If the
result hasn’t stabilized during that time the frame that is sent
contains the signs 0x20 in place of the result digits.
11 –STABILITY WAITING TIME
It specifies the waiting time for stabilizing the result. Time runs from the moment of requesting the
result by key pressing or serial interface request. The range of possible value settings is from 0 to
12 seconds. If the time was set at 0 seconds the result must be stable at the moment of requesting
the result. The default value of this parameter is 4 seconds.
12 –RECEIVING DATA LOCK
Setting value
Meaning
01^
LOCK OFF
The scale receives the commands via the PC Connector.
02
LOCK ON
Receiving the data via the PC Connector is locked.
NOTE: The automatic configuration with the ELZAB cash
registers is also inactive.

15 –FIXED TARE
Setting value
Meaning
01^
AUTOMATIC TURN OFF
Single pressing of the key switches on the tare but
doesn’t switch on the fixed tare. The fixed tare is switched on
only after pressing the key twice. If the “fixed tare” function is
switched off the tare will be automatically turned off after
weighing the articles and removing them from the platter.
