1. UNPACKING OF THE MAIN BALANCE
Cut open tape protecting the box. Take out the balance of factory package and
place it on a stable base. Take out all components and assemble them
according to below drawings:
Fig 1. The components installation for the balance with pan size 165 x 165mm
For balances 300 x 300mm or 410 x 410mm put on the pan and set the scale
working according to the chapter 2 of this manual.
Fig 1-1. The balance with pan size 300 x 300mm

6
Fig 1-2. The balance with pan size 410 x 410mm
Balances are supplied from 230 V AC / 11 V AC adapters. Connect to the
power source and turn on the balance.
2. INTENDED USE
Counting – labelling balances are designed for COUNTING PIECES OF THE
SAME MASS. Connection with label printer enables labels printing.
Balances are equipped with data bases of operators, assortments, labels and
contractors. Connected with bar code scanner searching out assortment by bar
code is possible.

7
Software of counting set makes possible:
-determining mass of single detail on main balance with highest
accuracy of weighing
-owing to application of graphic display, balance software is user-
friendly
-possibility of application PC type PS/2 keyboard simplifies moving in
software menu and data accessing
-printing basic labels, cumulative labels, „cc labels” (cumulative labels of
cumulative ones)
-cooperation with barcode scanner
-cooperation with additional balance platform
3. GETTING STARTED
3.1 Conditions of appropriate use
9place balance on a stable and flat table or free from vibrations
9balance should not be exposed to draughts and sudden air movements
9balance should be placed in room of stable temperature and humidity
9balance should be placed far from heat sources
9temperature of the room should be +15°C ÷+30°C (for WLT balances)
9if static electricity influence balances, indications, its base should be
earthed. Earthling clamp is in the back part of balance base
9balances should be levelled according to a level condition indicator to
guarantee the appropriate weighing accuracy
3.2 Time of warming-up
Before performing measurements wait until balance reaches temperature
stabilization. It is so-called warm-up time. It takes about 15 minutes.
For weighing instruments that have been stored in low temperatures (e.g.
during winter) the warm-up time is about 2 hours.
The indications of display may change during temperature stabilization.

8
3.3. Balance levelling
To do the measurements correctly level the scale. Take the pan off carefully
(without rapid pulls and hits) and turn the legs in order to level the balance, air
bubble should be place in the centre of level condition indicator.
Fig. 2. Balance levelling
1- correct levelling
2- incorrect levelling
4. UNDER-FLOOR WEIGHING
For scales with 165 x 165mm platforms can weigh underslinged loads (hanged
under the balance floor). In case of using this function:
−remove the hole plug made of plastic (placed in the balance floor),
−a suspension can be seen in the hole. It is standard equipment,
−Mount an appropriate hook for hanging loads (hook is non-standard
equipment).
1. The suspense cannot be rotated, revolved or tampered in any way,
because of direct connection with the weighing mechanism of the
balance.
2. All the additional elements like pan, string etc. should be tarred (TARE).
3. Balances with 300 x 300mm or 410 x 410mm platforms do not have the
under-floor weighing mechanism.

After introducing all changes in parameters settings press several times ESC
key. When display indicates message, choose one of two options:
ENTER – save changes
ESC – without saving
7. WEIGHING
Basic conditions which should be fulfilled to ensure reliability of measurements:
9stable base for balance,
9choice of appropriate parameters for existing external conditions
Before measurements or in case of essential changes of external conditions,
balance should be calibrated according to manual (for verified balances,
function of calibration is not accessible for user)
Before measurements check if unloaded balance indicates „precise zero” –
indicated pictogram - - in left lower corner (only when P4 06 Autozero
parameter is set on 1: yes or P4 07 for second platform), if balance doesn’t
indicates zero press key: .
If conditions for zeroing are unfavourable (lack of stable result), display
indicates horizontal lines. After exceeding set zeroing time of balance will
return to weighing without performing zeroing. In such case wait for
stabilization of conditions and press again key.
Place on the pan weighed load and when results are stable (indicated )
read on the display result of weighing.

7.1. Tarring
For determining net mass place on the pan package
of load and when indication is stable press Tkey.
Fig. 7a. Tarring – display view
1 –TARE signature (NET is being displayed)
2 –stable result signature
Tarring can be performed repeatedly in the whole balance weighing range.
Using tare function pay attention not to exceed the maximum weighing range.
After removing the load and package display will indicate mass equal to mass
of tare with minus sign.
Notice:
Tare value is not stored in balance memory and is deleted after disconnecting
from mains

20
7.2. Inscribing tare value
It is possible to inscribe tare value.
To do it in weighing mode follow the below instructions:
•Select the platform for tarring,
•Using PC keyboard inscribe a tare value (in basic unit) according to
display format e.g.: if the basic unit is “kg” and 0,005kg is a scale division
and you want to inscribe 1.05kg as a tare value, enter it in the following
format: 1.050,
•In the bottom left corner the editing field appears for inscribing a tare
value,
Fig. 7b. Inscribing tare – display view
1 – tare designator
2 – stability designator
3 – tare value
•press Tor F6 (PC keyboard),
•Tare can be inscribed any time.
Notice
Use “point” for decimal fractions.
7.3. Automatic tare
This function is useful for quick determining net mass of weighed goods when
tare values are different for each weighings. It is accessible in <P4 Readout>
parameters group.
