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
5
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.
6
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
9 place balance on a stable and flat table or free from vibrations
9 balance should not be exposed to draughts and sudd en air movements
9 balance should be placed in room of stable temperature and humidity
9 balance should be placed far from heat sources
9 temperature of the room should be +15°C ÷ +30°C (for WLT balances)
9 if static electricity influence balances, indications, its base should be
earthed. Earthling clamp is in the back part of balance base
9 balances 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.
7
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.

previous value – for main balance or displayed mass will not change.
key. Indication will return
21
Notice:
Balance zeroing determines a new zero point treated by balance as precise
zero. Zeroing is possible only in stable states of the indication.
8. BALANCE CALIBRATION
To ensure very high accuracy of weighing, periodical entering to memory
correction factor of balance indication referring to standard mass is required; it
is so called balance calibration. In WLT balances it is inaccessible for user. The
procedure of calibration can be performed only by authorized services of the
manufacturer.

For perfect conditions filter can be set as very fast, however if conditions are
bad (vibrations, draughts) filter should be set as slow or as very slow.
Effectiveness of filter operating is different for weighing range. Filter works
slower in time of “reaching” the final result, however stronger when mass gets
to set range of filter operating (parameter range of filter operating available only
in service menu – user do not have access to it).
11.2. Median filter setting
Task of median filter is to eliminate single big disturbances. By setting digital
value determines speed of filter operating. For zero option filter operating is off.

11.3. Setting the time of display refreshment
This parameter determines how often indication of display is refreshed. It is
realized by comparing what in given moment is on the display with information
sent by balance processor about state of weighed mass placed on the pan.
For higher refreshment parameters value display do not indicate intermediate
unstable mass indication by placing and removing the load on balance pan,
however for low values all changes of mass during weighing are visible – e.g.
this enables dosing loose or liquid materials. Time of refreshment is set in
seconds.
11.4. Setting of autozero operating
To ensure accurate balance indications software “AUTOZERO” function was
introduced. Task of this function is automatic control and correction of balance
zero indication.
When function is active comparison of successive results takes place in
declared distance of time e.g. every 1 s. If these result differ in value lower than
declared range of AUTOZERO e.g. 1 interval, balance will automatically zero
and markers of stable result –
and zero indication – will be
displayed.
When AUTOZERO function is on every measurement starts from precise zero.
There are some special cases when this function interrupts in measurem ents.
Example of it can be very slow placing the load on the pan (e.g. pouring the
load) in such case system of zero indication correction can also correct
indication of real mass of load. AUTOZERO can be switch on or off in
parameter P4 06 – main platform 07 – additional platform.
11.5. Last digit
To ensure appropriate comfort of operating with balance user determines
(depending on needs) if last digit of mass indication is to be displayed and in
which states of balance. One of below values can be set:
- 0 never
- 1 always
- 2 when stab
For verified balance option 1 – always is set (without possibility of changing)
