3. Technical conditions of installation and operation of the scale

3.1. Installation of the scale

x the scale should be placed on a stable and level surface,

x the scale should be leveled so that the air bubble level indicator was in the center of the

circle drawn on the indicator. Level the scale with adjustable bolts. After having leveled the scale check for stability (all bolts touch the ground) and whether the platter is correctly placed on the feet,

x if the scale is working with an external display mount the display on the countertop of the

cash box. Connect the display to the scale,

x connect the USB or RS232 scale interface cable with the communicating device. Do not

connect or disconnect the interface while using the scale as this may damage the interface.

3.2. Environment

x The scale can be operated at temperatures from -10 to +40 ° C and humidity up to 85% in

an atmosphere free from corrosive substances. After a sudden change in temperature by more than 5 ° C 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 formation 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.

x 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.

Page 9

ELZAB S.A. User Manual PRIMA 2 scale

3.3. Other operating remarks

x During turning on the power the platform 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.

x If during subsequent operations of the scale the weight indicator will be different from zero

it is needed to reset the scale with empty platter

 by pressing the

key (for small deviations) or

 by turning off and on the power supply of the scale or  perform the scale reset from the main menu.

x Avoid overloading or sudden load shocks of the platter. They can cause damage to the

mass transducer.

x 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.

x 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.

x 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 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. In order to precisely zero 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 to stabilize the load. After successful completion of the test the display should show:

Page 10

User Manual PRIMA 2 scale ELZAB S.A.

4.2. Weighing

The commodity should be placed as gently as possible 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

. When the maximum load is exceeded by 9 units

a message is indicated by displaying the

. 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 (e.g. 3,200kg):

4.3. Zero setting

The scale features the indicator signalizing that the scale was reset to zero. The indicator is lit if the current platter load is less than ¼ of e

unit.

Initial zero setting when turning on the scale

After turning on the scale and running the display test the scale will be set to zero. The display will show only zero values and the

. indicator will be lit. Zeroing is possible 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 the zero range the

message will be displayed and the scale

does not reset. 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

error is displayed and the scale does not

reset. In case of instability the zeroing is not effected and the

error is displayed.

Automatic zero setting for negative readings

This reset type is done automatically if during several seconds the scale readings are negative or the scale in under loaded. Other terms and conditions of zeroing are the same as for the reset 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 reset when the platter is unloaded. Other terms and conditions of zeroing are the same as for the reset with the use of the key.

Page 11

ELZAB S.A. User Manual PRIMA 2 scale

4.4. Tarring

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 value. In case of instability the tarring

is not effected and the

error is displayed.

The maximum tare value depends on the type of scale and is indicated in the Section

2.2

Specifications

of this manual.

Turning off the tare is effected after removing the load from the platter and pressing another time the

key or automatically after removing weighted commodity. In order the tare turns off

automatically there should be effected the process of weighing the commodity what 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 tarring:

–

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 imputed, the scale indicates 0.000 kg and the

indicators are lit,

– remove the load (a basket),

–

– 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 transit 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 =

. It is possible to input several tare values if

the consecutive tare values are growing.

Example of multiple inputting of the tare value:

The communication of the scale with external devices (e.g. cash register, computer) is effected via the CASH REGISTER/PC connector (RS-232 interface). To communicate via the USB connector the virtual serial port driver should be installed on the device cooperating with the scale. The driver can be downloaded from www.elzab.pl. The communication with external devices can be affected by functioning of the scale in the situations like: unstable result, overloading and under loading of the scale, transmission mode settings or the minimum result settings. The scale can react for those states in different ways depending on its settings.

All the communication parameters can be changed in the “User Menu”

. They are

permanently stored in the non volatile scale memory. The factory settings can be reset by using the

“Restore to factory settings”

function. The factory settings allow the scale to cooperate

with every cash register produced by ELZAB SA factory which was approved by the Ministry of

Finance since 2001.

6.1. Configuration of the communication parameters of the scale

Configuration of the communication parameters of the consists of choosing an appropriate

protocol by using the “Protocol type”

function. Selection of the protocol automatically sets default transmission parameters of the RS-232 interface for the given protocol. If the scale is working with the customized communication settings the transmission parameters of the RS-232

can be changed manually by the use of the “Transmission Speed”

and “Transmission

parameters” functions.

computer. This error is signalised after turning on the scale.

Three consecutive double signals (-*-*------,-*-*------,-*-*------)

To low power voltage (< 4,5V). Error signalized during

switching on or rest of the scale.

Three consecutive quadruple signals

(-*-*-*-*--,-*-*-*-*--,-*-*-*-*--)

To high power voltage (> 5,5V). Error signalized during

switching on or rest of the scale.

8. Conformity assessment (legalization)

Scales provided by ELZAB have undergone the conformity assessment procedure (legalization) and are ready for use in the trade settlements in accordance with applicable law. Confirmations of compliance with the above requirements are as follows:

1. large letter M on a green background placed on the scale nameplate,

2. set of metrological control characteristics, placed in accordance with the drawings set out below,

3. compliance of the markup number placed on the nameplate with the markup number stored in the non-volatile memory of the scale.

The markup number stored in the non-volatile memory of the scale can be checked any time, as follows:

1. The scale should be in the weighing mode and indicate the weight

kg.

2. Press the

key and hold it until the displays shows the scale menu: .

3. Pressing the

or key go to the menu item: .

4. Press the

key. The display will show the markup number stored in the non-volatile

Page 28

User Manual PRIMA 2 scale ELZAB S.A.

Damage to the scale nameplate, to the metrological control characteristics or non-compliance of the markup number placed on the scale nameplate with the markup number from the non-volatile memory of the scale means the loss of validity of legalization. That scale may not be used for trade settlements and must be re-legalized. Also reparation of the scale may require its re-legalization.

The confirmation of the conformity assessment is the Declaration of Conformity, a copy can be downloaded from www.elzab.pl. A copy of the declaration may be required during the relegalization of the scale.

Periodical re-legalization is required to meet national laws. Please consult this requirement in organization that has competence in this area of activity.

The obligation to undergo the periodic re-legalization and maintain the security features intact lies with the user of the scale.
