1. INTENDED USE
The balances are used to do precise measurements in laboratories.
It is possible to do the zero function in all measure range.
The balance weights in following units:
Measure units
Apart from weighing in various measure units the balance also:
• counts pieces
• weights
• filling
• percent
• weights animals
• determines liquids and solids density
• formulation
• creates statistics
Measure units and particular functions can be inaccessible for u ser.
It is possible to adapt the balance to individual needs and access
functions and units which are necessary at this moment.
It is possible to define accessible or no-accessible in user menu
and it is described in further part of the manual.
2. PRECAUTIONARY MEASURES
A. Please, read carefully this user manual before and use the device
according to its intended use.
B. If the device is about to operate in a strong electrostatic field
(e.g. printing houses etc.) it should be connected to the earthing.
Connect it to the clamp terminal signed
.

4. UNPACKING OF THE BALANCE
4.1. WTX series
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:
- 6 -
4.2. WLX series
Unpack and put the scale on a flat even stable surface far away from
sources of heat and then:
• Remove transport protections
• Install the weighing pan according to the drawing below:
5. GETTING STARTED
5.1. Conditions of appropriate use
• Place balance on a stable and flat table or free from vibrations
• Bbalance should not be exposed to draughts and sudden air
movements
• Balance should be placed in room of stable temperature and humidity
• Balance should be placed far from heat sources
• If static electricity influence balances, indications, its base should be
earthed. Earthing clamp is in the back part of balance base
• Balances should be levelled according to a level condition indicator
to guarantee the appropriate weighing accuracy.
- 7 -
5.2. Time of warming up
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.
1 - correct levelling
2 - incorrect levelling
5.3. Balance levelling
Before performing measurements wait until balance reaches temp erature
stabilization. It is so-called warm-up time. It takes about 15 minutes.
For weighing instruments that have been stored in low tempe ratures
(e.g. during winter) the warm-up time is about 2 hours.

submenu described as Function,
• Attribute activation for submenu which is indicated (digit flashing
means the value can be changed and some characters can be
written).
7.3. Navigating within the menu
User moves in the menu by:
• the balance keyboard,
• PS keyboard.

7.4. Return to weighing
Introduced changes in settings will be saved after return to
weighing mode with procedure of saving changes. 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
8. WEIGHING
Following conditions must be fulfilled to get reliable results:
• Stable temperature
• Stable ground
• Proper parameters for external conditions
Before measurements load the pan and check if the balance show
„precise zero” – displayed
in down left corner of the display
(only if the parameter <P4 06 Autozero> has the value 1: yes) and
check if the measurement is stable –
is displayed in right up
corner of the display. If the balance does not show zero press
the key
If the conditions are unfavourable (no stable result) lines appear on
the display. After settled time the balance returns to weighing mode
without set up to zero. In this case wait until the conditions stabilize
and press Esc again.
By the Units key select measure unit. Put the load on the pan and
after stabilization read out the result. If measure unit user wants to
use is not displayed during pressing the Units key check if it has
access attribute.
The indication can be set to zero many times. Sum of loads noted
in the balance memory cannot be higher than max capacity.
Between following measurements do not unplugged the balance.
The balance should be switched off by the ON/OFF key. After
pressing the key again the balance is ready to work without warm
stabilization.
- 15 -
8.1. Tarring
For determining net mass place on the pan package of load and when
indication is stable press
key.
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
8.2. Manual inscribing of tare value
Inscribing the tare value in weighing mode:
• Inscribe a tare value in a display format e.g. if a basic unit is „kg”
with a division 0,005kg and you want to enter 1.05kg as a tare value,
inscribe it as: 1.050,
• After pressing the first digit you can see an editing field in the last line.
Inscribing tare value – display view
1 TARE value entered
2 stable measurement pictogram
3 inscribed tare value
- 16 -
• Press T key
• You will see the tare value with “– “ sign on the display
• Tare value can be inscribed any time during weighing
Notice
Use “point” for decimal fractions.
8.3. 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.
Enabling function:
Automatic tare – enabling
After setting an appropriate value of the parameter return to weighing
7.4. of this manual.
The way of operation:
• Press ZERO button when the pan is empty,
• Put a package on the pan,
• After stabilizing tarring is performed (Net designator is displayed
in the top left corner of the display),
• Put an article on the pan,
• The display shows the net mass of the article,
• Unload the pan,
• Indication returns to zero,
• Put the next package … and the cycle repeats.
- 17 -
8.4. Zeroing
For zeroing display indication press
key. Indication will return to zero
and display will indicate a graphic signature in left lower corner
.
Zeroing of indication is possible only in range of 2% of maximum capacity
currently displayed balance/platform. If zeroed value is bigger than 2% of
maximum capacity display will indicate error message and return to
displaying previous value – for main balance or displayed mass will
not change.
Notice:
Balance zeroing determines a new zero point treated by balance as precise
zero. Zeroing is possible only in stable states of the indication.

9. 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. The procedure of calibration
can be performed only by authorized services of the manufacturer.
