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 antidraft 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 temperatu re st abili z at ion 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.

- 7 -

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

- 19 -

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 passwor d sett ing s (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 softw are wi ll 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 – fu nct ion ac tivat ing

- 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.

7. ADJUSTMENT

In order to ensure the highest measuring accuracy, it is recommended to periodically introduce to balance memory a corrective factor of indications in relation to a mass standard – i.e. balance adjustment.

Adjustment should be carried out:

- Before the beginning of a weighing procedure,

- If long breaks between following measuring series occur

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

Types of adjustment

- Internal automatic adjustment

* triggered by temperature change * triggered by elapsing time

- Manual internal adjustment

* initiated from balance’s keyboard

- Adjustment with external weight

* with declared mass which cannot be modified * with optional mass which needs to be specified before process initiation

(only in non-verified balances)

Caution:

In case of verified balances only the automatic internal adjustment and manual internal adjustment systems are available for a user.

Remember to Perform the adjustment when there is no load on the pan!

7.1. Internal automatic adjustment

Activation of automatic internal adjustment is triggered on:

- Elapsing a specified amount of time from last carried out adjustment

process, or

- Ambient temperature changes by a value specified by the balance

manufacturer.

* in case of balance AS/X series it is 0,8°C, On recognizing any of the above case, balance’s display shows the following message box.
