1. UNPACKING AND ASSEMBLING
1.1. Balance AS/X series
Cut the protective tape of balance’s factory packaging. Carefully remove the
balance from its packaging. Take out from the box all the accessories needed for
correct operation of a balance. Place the balance in its inteded place of use and
assembly its components as specified in below scheme. The balance is powered
from mains through a power adapter 13,5-16V DC.
• Open side glass door of the weighing
chamber,
• Inside the weighing chamber place
bottom metal plate (5),
• Next place a centering ring (3) onto
the bottom metal plate,
• Inside the centering ring assembly
the weighing pan (2),
• Inside the weighing chamber and
onto the centering ring place an anti-
draft shield (1),
• Close the side glass doors of the
weighing chamber,
• Plug the balance to mains using the
dedicated power adapter. The power
socket for plugging the power
adapter’s pin is located at the back of
balance’s housing.

2. STARTUP
2.1. Intended use
• The balance should be located on a stable wall console desk or a stable working table
which is not affected by vibrations and distant from heat sources.
• Balance should be used in locations free of gusts of air and drafts.
• Operate the balance in a room with stabilized temperature and humidity conditions.
• Ambient air temperature should not exceed the range of +10°C ÷ +40°C
• In order to avoid influence of static electricity on the measurement process, ground
the balance’s housing. The grounding bolt is located at the back of balance’s housing,
• The balance should be set to level using the level indicator located at the back of
balance’s housing. Leveling the balance is one of the conditions for ensuring required
measuring accuracy.
• Before unplugging the balance from mains always switch of the display by pressing
ON/OFF key
2.2. Leveling
Before plugging to mains, level the device using two adjusting feet located at the back of
balance’s housing. Turn the adjusting feet in a way that the air bubble of the level is placed
centrally. The level is located at the back wall of balance’s housing.
2.3. Balance temperature stabilization period
Before start of measuring processes, it is necessary to wait until the balance is thermally
stabilized. It is a period of so called balance self-heating time.
In case of analytical balance AS/X series self-heating period takes approximately 1 hour.
The specified time interval refers to balances that have been stored in room temperature
before plugging to mains.
For balances that were stored in much lower temperatures before plugging to mains (e.g.
during winter period) thermal stabilization should last approximately 8 hours. During
temperature stabilization time the indications on balance’s display may change.

3. APPLICATION
Balance featuring a graphic display is intended to precise determining mass in laboratory
conditions. The balance enables zeroing the indication in whole measuring range.
Balance AS/X series enables determining mass in the following measuring units:
Fig. 2. Measuring units
Apart from determining mass of weighed object using different measuring units, the
software balance AS/X series comprises the following working modes:
− parts counting
− checkweighing
− filling (doing)
− percent setup
− animal weighing
− determining density of solids and liquids
− mixtures from accepted formulation and ingredients
− formula making
− pipette calibration
− statistics
Both measuring units and working modes can be set as inaccessible in the user menu.
This option is implemented for the purpose of adjusting balance to user needs and
requirements, i.e. providing access only to those functions and units which are required by
a user.

6. WEIGHING
Basic working conditions for obtaining reliable measurement results:
- Stable and constant temperature in a weighing room,
- Stable foundation of a balance,
- Selecting adequate balance settings adjusted to ambient conditions at a
workstation.
Before start of weighing process or in case of essential change of ambient
conditions at a workstation (e.g. ambient temperature change at a workstation more
than 1°C/h) the balance requires adjusting. The procedure of balance adjustment is
described in point 7.1. of this user manual.
Before start of weighing procedure, it is recommended to load the balance’s
weighing pan a few times with mass close to balance max capacity. Check if
unloaded balance indicates “precise zero” (the pictogram is visible on in the
upper left corner of balance’s display) (and only if parameter P4 06 Autozero is set
to 1: yes) and whether measurement is stable – (the pictogram is visible in the
upper right corner of the display. If the mass indication is other than zero, press
zeroing key:
If the working conditions are unfavourable (i.e. unstable measurement result), then
the display previews dashes (horizontal lines). After exceeding a preset amount of
time for zeroing the indication, the balance returns to weighing mode without zeroing
the indication. In such case the user should wait for stabilization of working
conditions and once again press Esc key.
Press Units key to set a measuring unit. Place weighed object on balance’s
weighing pan and read the result only on stabilization of the measurement. If the
measuring unit is not displayed on pressing the Units key, then go to the
corresponding submenu and check the accessibility attribute of the measuring unit.
Mass indication of a load placed on balance’s weighing pan can be zeroed for
multiple times. Pay attention not to exceed maximal capacity of a balance by
applying multiple zeroing function.
During times between carrying out the following measurement series do not unplug
the balance from mains. It is recommended to switch off balance’s display by
pressing ON/OFF key. On repeated pressing of the ON/OFF key the balance is
ready for operation and does not require thermal stabilization.
Recommended balance settings while weighing small mass ( ≤0,6g) and
with reference to ambient conditions at a workstation:
- filtering level AuE: the slowest
- value release ConF: reliable

6.1. User log in
The users of a balance AS/X series can have their specific access code to the balance’s
menu. The password system is determined by balance’s administrator, i.e. a user of the
higher order in relation to the other balance users. The access password can comprise up
to 6 digits.
Balance software enables determining:
• A single Administrator, who has access to all balance settings and software
functions, including changing the password of the administrator and other users.
• A single User who is authorized to access balance settings and functions, as set
by the balance administrator
Setting passwords and access levels
• Remember, that after the first entering the password settings (see parameter P9
13 Password protection), the user should set a password for the balance
Administrator.
• The software requires inserting an administrator password when entering
parameter P9 13 Password protection only if the administrator password is other
than “0”.
• On the following entering this parameter, the software will require inserting the
administrator’s password. Access to parameter settings of submenu P9 13
Password protection will be granted only on entering correct password.
Unless the password is correct, the balance displays a message on incorrect
password and goes back to displaying previous screen.
• Depending on the settings, the inserted password is previewed either as
a sequence of digits or as asterisks (the initial value of each entered digit is
always = 0).
Following the point 5.1.1 menu P9 Other contains the following options
Fig. 9. Password – function activating

- 20 -
Fig. 9-1. Password protection – menu content
- Administrator
the field for inserting administrator’s password. Balance administrator has access to
all balance functions and settings.
- User
the field for inserting user’s password. Balance user has access to the functions
and settings which attribute is set to NO (i.e. no password protection).
- Startup
if the option is set to YES, then on balance startup the software requires entering a
password (of the administrator or user).
- Functions
if the option is set to NO (i.e. no password protection), balance user can use all
working modes implemented in the balance software.
- Settings
if the option is set to NO (i.e. no password protection), balance user can change
balance settings.
- Cal + GLP only
if the option is set to YES, then balance user has access only to carrying out balance
adjustment /calibration and generating a report from adjustment process.
- Asterisk
if the option is set to YES , then on balance startup the entered password is
previewed in a form of asterisks.
Inserting Administrator’s password
Enter a password for the balance administrator (a sequence of 6 digits) and for the
user. Balance administrator has full access to balance menu. The user access is
limited to the one described in previous point (balance menu, startup, adjustment, etc.
options can be attributed YES/NO).
It is very important to remember the password, as if option “password on startup” is
enabled (set to YES), then on the following plugging the balance to mains, the
software will request for entering the password. If it is entered incorrectly, then balance
operating will be blocked.
While entering the password use balance keys presented on Fig. 2 or use external
keyboard PS/2 type connectable to balance’s socket.
Set availability to other balance settings and functions, depending on access level
required by the balance user.
