1. General description.
B/U series platform scales are destined for general use.
B series scales are made in two main versions: with LE display (basic) and with
LC display (option).
ouble-range option is described In Appendix A
All scales are metrological tested - calibration or legal verification on demand.
Scales have following verification features:
- a seal protecting scale casing against opening,
- notified body stamps and green metrological marking placed on the balance
name plate.
Legal verification is valid for 3 years unless the seal is broken.

5. Sec rity r les
To avoid electrical shock or damage of the scale 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
scale). Pay attention that supply voltage is compatible with specified
technical data.
• o not use the scale when its cover is opened.
• o not use the scale in explosive conditions.
• o not use the scale in high humidity.
• If the scale seems not to operate properly, unplug it from the mains and do
not use until checked by authorised service.
6. Environment protection
According to legal regulations it if forbidden to dispose
wasted electronic equipment in waste containers.
• Please return wasted scale to the point of purchase or other company
specialised in recycling of wasted electronic components.

8 USER MANUAL
_____________________________________________________________________________________________________________________
7. Preparation to work
1. Take the scale out of the package
removing protective foils.
2. Take a pan off and remove protective
elements from below the pan.
3. Place the scale on a stable ground not
affected by mechanical vibrations and
airflows.
4. Level the scale with the rotating rear legs
so that the air bubble in the water-level at
the back of the scale is in the middle. Lock
the legs with the nut.
Correct Wrong
5. Put on the pan.
6. Plug the feeder connector to the power
socket at the back of the scale and plug the
feeder to the mains. After self-tests and
result stabilisation, the scale displays zero
indication.

USER MANUAL 9
_____________________________________________________________________________________________________________________
8. Start- p
Leave the pan empty, plug the feeder to the mains (~230V/50Hz) and plug the
feeder connector to the 12V power socket at the back of the scale.
The scale proceeds with following start-up actions:
isplay test.
Basic electronic components tests: C1,
C-2, C-6 .
Program version.
The scale is now ready to work.
Note:
In scales with power feeder please plug in feeder to wall socket first, and
connect feeder plug to scale next.

10 USER MANUAL
_____________________________________________________________________________________________________________________
9. General r les
1. Before each measurement make sure that zero indicator is displayed. If zero
indicator does not displayed or “----“ communicate appears, press →0← key
and wait until zero indication and zero indicator appears
2. The scale is equipped with a tare equal to its range. To tare the scale press
→T← key (left or right). Storing a tare value does not extend measuring range,
but only subtracts it from a load placed on a pan. To make weight control easier
and to avoid range overdrawing, the scale is equipped with a load indicator
(graduated in percentages).
3. Weighing result should be read when the indicator " " lights, which signalises
stabilisation of a result.
4. When the scale is not used but it is necessary to be ready to work immediately, it
can be switched off by pressing I/ key. The scale reading system is then
switched off to "standby" mode (signalled by the indicator "OFF" in version
with the LC display). To switch the scale on press I/ key. The scale is
immediately ready to operate maximum accuracy (after self tests).
5. Weighed sample should be placed in the centre of the pan.
6. Protect the scale against dust, aggressive dusts and liquids. To clean the scale
wash it with water with soap and dry it afterwards.
Place the scale on a platform to avoid dropping weighed objects
on the pan.
.
Do not overload the scale more then 20% of maximum load (Max .

USER MANUAL 11
_____________________________________________________________________________________________________________________
10. Balance checking
It is advised to check scale indication accuracy before and after series of
measurement using any load with known weight.
To check the scale with legal verification use a calibration weight with valid
calibration certificate. In case permissible error is exceeded it is advised to contact
the nearest service to calibrate the scale
11. Scale adj stment
To adjust a balance it is necessary to break protective marks, therefore
to calibrate the scale please contact the nearest service
.
12. Connecting to a comp ter, printer or label printer
The scale is equipped with RS232C or
RS485 (optional), which can be used to
connect external devices such as a computer
or a printer. etailed way of communication
data is defined by one of protocol:
- LonG – protocol to printer and computer
- ELtron – protocol to label printer
When cooperating with a printer data is send
automatically after result stabilisation, but
next transmission is possible after removing
previously weighted sample.
When protocol Long is chosen scale sends
result of weighting under the influence of
initializing signal from computer, or after
pressing a key.
When automatic transmission mode is
chosen (function PrInt), a printer data is send
automatically after result stabilisation, but
next transmission is possible after removing
previously weighted sample. The scale sends
following information: successive number of
weighing, date and time (if clock module is
installed )and weighing result.
uring transmission communicate Print is displayed. It is also possible by scale to
display text message sent from computer confirming received information.

Scale with Eltron protocol sending record of data after pressed key.
The scale sends following information: number of label, date and time (if clock
module is installed ) and weighing result. uring transmission communicate Label
is displayed.
In special features scale can be equipped in second RS232 interface for additional
functions, ex. continuous transmitting of indications to second display.
Computer must have a special program for cooperation with data from a scale.
