*- when any problems with electrostatics occurs humidity of air should be increased to 50%, but when it is not possible to
keep 50% humidity the ionizer should be used to eliminate electrostatic effects on balance indications.

2. UNWRAPING THE BALANCE
2.1. The balance CX
Cut safety tape off. Take balance off the box. Take all necessary to correct
performance of balance elements off the box. After replace balance in place of use put
- 6 -
scale and rest of elements on. The balance is supplied with 230 V AC / 11V AC
supplier.
The balance with Φ85 mm pan:
-open side doors of weighing chamber,
-inside the chamber place lower shield of
weighing chamber(4),
-put centering ring on the shield (3),
-put the balance pan inside the ring (2),
-put the anti-breeze shield on the
centering ring (1),
−close side doors of weighing
chamber,
−turn on balance supply,
−pin of power adaptor should be
connected to socket in the back
of balance casing.
The balance with Φ100 mm pan:
-open side doors of weighing chamber,
-inside the chamber place lower shield of
weighing chamber (3),
-inside the chamber place anti-breeze
shield (2),
-put the balance pan inside the ring (1),
−close side doors of weighing
chamber,
−turn on balance supply,
−pin of power adaptor should be
connected to socket in the back
of balance casing.

The balance with pipettes calibration set:
-slide chamber side doors off (8)
-inside the chamber put bottom ring
(8),
-put glass ring on bottom ring (7),
-replace pan inside glass ring (6),
-put upper ring on glass ring (5),
-put steam protection container on
upper ring (4),
-put container to pipettes calibration
inside the container (3),
-put glass pad on upper ring (2),
-put glass lid on glass pad (1).

3. START THE BALANCE UP
3.1. Conditions of proper usage
−Set the balance on stable table, far from vibrations
−The balance should be replaced far from draughts and air breeze.
−The balance should be in stable temperature and humidity room
−The balance should be replaced far from sources of
−Temperature in the room +18°C ÷+30°C ( AS /X)
−If the static electricity has influence on the balance indications it base should be
earthed. Earthing screw is in the rear part of the balance base.
−The balance should be replaced in leveled position
−Before pipettes calibration and after assembling the set start the balance with
empty pan on (without container). When zeros come up on the display put
the container on the pan and after stabilization press ESC/ZERO TARA.

3.2. Set level up
After replacing the balance in the place of usage the balance should be leveled. The
correct leveling is shown on the level indication installed at the rear of the balance. The air
bubble should be in the centre position of the indication.
3.3. Warmin up
Before measurements user should wait untill the balance reaches temperature
stabilization. It is warming up time.
For analytical balances warming-up time is about 1 hour. This periods refers to the
balances which ware in surrounding temperature (work) before start weighing.
If the analytical balances are kept in lower temperature(for example in winter time) before
weighing the warming-up time is about 8 hours and for precision balances it is about 2
hours.
During warm-up stabilization the indications can change.
4. APPROPRATION
The balances with graphic display 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:
Draw. 2. Measure units
Apart from weighing in various units the balances have additional functions as:
−counts pieces
−weights
−dosages
−determines deviations of the standard mass
- 9 -
−weights animals
−detemines liquids and solids density
−making mixtures up to recipes
−statistics of measurements series
−recipes
Measure units and particular functions can be inaccessible for user. 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.

5.2. Keyboard
Each key is dual-function key. Particular function can be done through. User also can
move in the balance menu.
ON/OFF key, switches the display off, after switching off other
subcomponents are supplied and the balance is in stand by
mode.
Function key F,fast enter into work mode
Key MODE – selects the work mode
UNITS key, changes measure units
PRINT/ENTER key – sends information to external instrument
(PRINT) or confirms parameter value or function (ENTER).
Key ESC/ZEROTARA – sets indication to zero
