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 repl

acing 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.

7. WEIGHING

Follo

wing conditions must be fulfilled to get reliable results:

- Stable temperature

- Stable ground

- Proper parameters for external conditions

Before measurements or for essential changes of the external conditions (if the
temperature changes more than 1° C/h) calibrate the balance in accordance with p.

7.1.

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 untill 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.

- 19 -

The indication can be set to zero many times. Sum of loads noted in the balance
memory cannot be higher than max capacity.

Betwenn following measurements do not unpluged 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.

7.1. Pipettes calibration

In specia

l function or via cooperation with special computer software PIPETTES user
can calibrate pipettes (pipettes calibration stand). Function is described in further part of
manual.

Independently on pipettes calibration for this function steam protection ring must be
installed on (see point Unpacking balance). Container of steam curtain minimizes errors of
measurement when liquid evaporates during weighing.

Before pipettes calibration pour water to steam protection ring to 2/3 height of ring.

The set is ready to use after about an hour –this time is necessary to get moisture
stability. Remember to control distilling water level in container – surface of container

- 20 -

should be covered with water all the time. Overflow of water in container can be removed
with automatic pump or pipette.

To minimize all humidity measurements inside chamber and influence of blast air
during opening side doors the dosing liquid from pipettes must be done through a hole in
upper cover of weighing chamber.

7.2. Log-in function

The operator has own access code to internal menu. The password system is defined by
administrator. Password can contain max 6 digits.

The balance program enables to declare:

• One administrator who is authorised to use all sets and programme functions,
change the passwords – own and user

• One user who is authorised to sets and the balance functions determined by
administrator

Setting password and access authorization

• After set the password and access parameters (parameter P9 13 Password
protection) write the password for administrator

• If the admistrator password is different from “0” the program wants administrator
password during enter for the parameter
P9 13 Password protection.

• Every enter this parameter the software demands administrator password, after
writting correct password it is possible to set the parameter P9 13 Password
protection

• If the password is not correct the command about wrong password is show and
the balance displays previous window

• Dependly on setting the password is shown as digits or stars (start value each

Write the password for administrator (max 6 digits) and user. Each admistrator has
access to all functions in the balance. User has access to balance possibilities in
accordance with above description. Please, remember the password. If you set YES
for „Start up” function the password must be writen after switch the balance on.
If the password is not correct using the balance is not possible.

To write the password in use keys described on the drawing 2. or PS/2 keyboard (it
can be connected to the balance port).

Set up the attributes for other options dependly on authorizations for user.

8. BALANCE CALIBRATION

To ensure high precision of weighing corrective factor in relation to standard mass must be
noted in the balance memory periodicaly – it is the balance calibration.

Calibration should be performed when:

- The weighing is started,

- Long breaks are between following measure series

- Temperature inside the balance changes more than: 0,8° C

Kind of calibration:

- Internal automatic calibration

- * started if temperature changes, started if the time changes

- Internal manual calibration

* started by the balance keyboard

- Calibration made with external weight

- with declared mass which cannot be modificated

- * with any mass which should be given before the calibration process(for not

legalized balances only)

In verified balances only automatic internal calibration and manu al internal calibration is
accessible.

Perform the calibration when there is no load on the pan!

8.1. Automatic balance calibration

It is performed w

hen:

- Period of time passes from last calibration

- temperature changes for settled value by manufacturer

* for balances XA/X is 0,8° C,

Following information appears on the display:

17.9. Calibration of pipettes

F

unction of pipettes calibration refers to pipettes with stable and changeable capacity.
During the procedure precision and repeatability errors both are defined. For pipettes with
changeable capacity errors are defined for Max, Min and ½ Max.

All pipettes are checked according to precision and repeatability norm PN-EN ISO
8655:2003.

- 58 -

To ensure precise measurements keep following environmental conditions:

 Temperature of environment, tip and liquid should be 20°C - 25°C stabilized

during weighing in range of ± 0.5.C

 Moisture about 50 - 75%

Use distillated water only in a calibration process.

Before calibration following data must be loaded:

- Pipette [stable /changeable capacity]

- capacity Vmax [ml]

- capacity V1/2max [ml]

- capacity Vmin [ml]

- Error of capacity Vmax [%]

- Error of capacity V1/2max [%]

Question mark before load mass means that the result is not stable.

18.2. Non-standard printout

Proced

ure of creating non-standard printouts:

− user can create own 4 printouts,

− give the number of the text which starts the printout eg. Printout 1 Start – 1 and

text number which finishes the printout eg. Printout 1 Stop – 40. In this case texts
from 1 to 40 are printed.

− And then write text in the lines 1 ÷ 40.

It is recomended to use PC keyboard what is simplier and faster way.

− Non-standard printouts can overlap each other:

Printout 1 Start – 1

Printout 1 Stop – 40
Printout 2 Start – 20
Printout 2 Stop – 40

Non-standard printout can be created by Edition of the printout.

During manual writting give all special signs as CRLF, tabul ator etc. If function Printout
Edition is used all these values can be selected in form of ready elements. They are
transmitted from one side Line of selection to the other window Printout

Draw. 61. Menu printouts –the function activation
