1. Introduction

Electrical balance BT series are designed for use in laboratories and many others technical applications, where
high measurements precision is not required.
All balances are metrologically tested by manufacturer and they are not designed for calibration certificate.
According to order, balances may be calibrated.
Balances classification (PKWiU code) 33.20.31.

3. Security rules

To avoid electrical shock or damage of the balance or connected

peripheral devices, it is necessary to follow the security rules below.

• All repairs and necessary regulations can be made by authorised personnel only.

• To avoid fire risk use a feeder of an appropriate type (supplied with the balance). Pay

attention that supply voltage is compatible with specified technical data.

• Do not use the balance when its cover is opened.

• Do not use the balance in explosive conditions.

• Do not use the balance in high humidity.

• If the balance seems not to operate properly, unplug it from the mains and do not use until

checked by authorised service.

According to legal regulations it if forbidden to dispose electronic

equipment in waste containers.

• Please return wasted balance to the point of purchase or other company specialised in
recycling of wasted electronic components.

7. Workplace preparation for balance

Balance workplace should be choice carefully in order to reduce influence of factors, that could disturb balance
operation. The workplace should assure appropriate work temperature of balance and necessary space for
normal balance operation. The balance should stand on stable table that is made of material non–affecting
magnetic on balance.
Sudden motion of air, vibration, dustiness, violent changes of temperature and humidity above 90% are
forbidden. The balance should stay away from heat sources and devices that emit strong electromagnetic
radiation and magnetic field.

8. Balance preparation for work

1. Remove balance and power supply unit from
the package.

2. Place the balance on stable foundation, in place
not subjected to mechanical vibrations and air
movements.

3. Unscrew protection rod 10

and take it out with

protection cap 11

(if it appears in scale). Into the

same place push decorating button 12.

4. Adjust the balance level, using the rotary legs,
so the air bubble in the level 7

located in rear part

of balance, takes the central position.

5. Connect together walls edges of pan cover 8.

6. Put pan cover on balance and cover the lid 9.

9. General principles regarding balance operation

1. During balance operation, in order to confirm its efficiency, it is recommended to check
the weighing precision by putting a object of exactly known weight before and after series of measure-
ments. In case of allowable measurement error exceeding it is recommend to make calibration by
standard weight or contact authorized Service Company to perform balance adjustment.

2. Weighed mass should be placed in the pan centre.

3. The balance enables tare setting in the whole measuring range. It is performed by pressing "

→T←

" key.
Tare setting does not widen measurement range. It only subtracts tare weight from the mass, currently placed
on the balance. To facilitate the mass control on the pan, and avoid the range exceeding, the balances have the
load indicator, scaled in 0÷100%.

4. The weighing result should be read during the " " indicator lighting, which indicates the result stabilization.

5. When there is no weighing, but the balance should be ready for operation, it may be switched off by I/
key. It turns balance reading system off and entering into the standby mode that is indicated by OFF.

Balance turning on is performed by pressing " I/ " key.

6. In balances with active

→0←

key (zeroing) before putting weighed mass on the balance, make sure, if

zeroing indicator

→0←

is displayed if the zero indication is not shown, press

→0←

key and wait for balance

zeroing and zero indicator appears. Only then you can put an object on the balance.

7. Balance mechanism is very precision device and sensitive to overload, shocks and impacts.

10. Balance operation principles with power supply form accumulator (battery)

1. The balances can be supply from ~230V mains thought power pack delivered with the balance. Moreover

accumulators also can be used. They can be placed in box inside balance. It is possible to use normal
batteries.

2. To extant work time of accumulators (battery), it is possible to turn off display and next balance

automatically. The settings of timer operation is made by b_LIGHT and Auto OFF functions.

If balance was moved from environment with lower temperature to the room with higher

temperature, condensate can be formed on the surface of balance. In this situation it is

forbidden to turn balance on, because balance can be damaged. Before turning on

balance, it should stay in a new environment for 4 hours in order to acclimatization.

Do not overload the balance over 20% of maximum load.

Make sure, that pan is secured against accidental stress on the period of transport.

In order to exchange accumulators for batteries it is necessary to turn off

charging accumulators, by bAttErY function (bAt OFF option ) that is descrapt

in the further manual part.
