3. Safety rules
It is necessary to follow safety rules of work with the scale
shown below. Obeying those rules is the condition to
avoid electrical shock or damage of the scale or
connected peripheral devices.
All repairs and necessary regulations can be made by authorised personnel
only.
To avoid fire risk use a feeder of an appropriate type (if feeder is supplied
with the scale) and supply voltage has to be compatible with specified
technical data.
Do not use the scale when its cover is opened.
Do not use the scale in explosive conditions.
Do not use the scale in high humidity environment.
If the scale seems not to operate properly, switch it off and do not use until
checked by authorised service.
According to current acts of low about protection of
natural environment, wasted scales should not be put into
waste containers together with ordinary waste.
Wasted scale after operation period can be delivered to units authorized for
gathering wasted electronic devices or to the place where it was bought.

7. Preparing working environment
+33°C
+18°C
Location for the scale should be chosen with care in order to limit influence of the
factors that can interrupt working scale. This location has to maintain proper
temperature for working scale and necessary space for its operating. The scale should
stay on stable table made of material that does not influence magnetically on the
scale.
Rapid air blasts, vibrations, dust, rapid temperature changes or air humidity over 90%
are not allowed in scale surrounding. The scale should be far from heat sources and
devices emitting strong electromagnetic or magnetic fields.

9. General operation principles
1. In order to confirm correctness of the scale during its operation, before starting and
after finishing every valid measurement series it is recommended to check weighing
accuracy putting calibration weight or other object of exactly kno wn mass on the
scale. In the case when allowable measurement error of the scale is exceeded, it is
recommended to perform calibration with external weight or contact authorised
service centre.
2. Weighed mass should be placed in the middle of the pan.
3. The scale allows taring in the whole measuring range. To tare the scale press
->T<- key. Taring does not extend measuring range, but only subtracts tare value
from mass value of a sample placed on the pan. To make the control of a load on
the pan easier and to avoid exceeding measurement range, the scales have load
indicator calibrated 0÷100%.
4. Weighing result should be read when the indicator lights, which signalises
result stabilisation.
5. When the scale is not used but it is necessary for it to be ready to work, it can be
switched off by pressing I/ key. The scale reading system is then switched off and
scale goes to standby mode signalled with OFF indicator. Switching the scale on is
preformed by pressing I/ key.
6. In sales having →0← key (zeroing) active it should be checked if zero indicator
→0← is displayed before sample is placed on the pan. If not, press →0← key and
wait until the scale is zeroed and zero indicator appears. After that load can be
placed on scale pan.
7. Scale mechanism is a precise device sensitive to overweight, mechanical shocks
and strokes.
8. After every change of balance position, level the balance and perform internal
calibration.
Do not overload the scale more than 20% of maximum capacity.
Do not press the pan with a hand.
For transportation time, pan support and pan ring should be packed
separately.

11. Internal calibration
The balance is equipped with internal calibration system, which general task is to
maintain required measurement accuracy on the balance.
Internal calibration is the process of putting internal weight on automatically by
balance mechanism and correcting accuracy in balance firmware. The correction is
necessary because of differences between values of gravitational acceleration in
the place where the balance was manufactured and in the place where it is
operated, as well as due to changes of balance level and temperature.
Internal calibration is performed in the following situations:
- when key is pressed twice,
- after defined time interval (for balances comply with verification requirements - 2
hours),
- after temperature change (for balances comply with verification requirements –
more than 2oC).
For balances comply with verification requirements time interval is set to 2 hours and
defined temperature change is 1oC. In other balances those values can be set as
calibration options. The reason of starting internal calibration is shown as an icon near
weight picture.
In order to perform internal calibration

proceed with the following:
Empty the pan.
Press key twice (double pressing
the key helps to avoid accidental
starting calibration procedure).
During calibration internal weight is

results are compared.
Discrepancy of results is signalled
with a message and causes the
balance being blocked.
Until calibration process is finished do
not perform any operation on the
balance. Any vibrations and shocks
interfere calibration process and may
delay it or deteriorate accuracy of its
result.
When internal calibration is performed
successfully the balance indicates
zero on the display at empty pan.

Note:
In order to terminate internal calibration process in balances not comply with
verification requirements press key and wait until balance mechanism is not
settled in initial position.
12. Checking the balance
In order to confirm correctness of the balance during its operation, before starting and
after finishing every measurement series it is advised to check weighing accuracy. It
can be done by weighing external calibration weight or other object with exactly known
mass.
If exceeding of allowable measurement error is affirmed, the following things should
be checked:
- if the balance stands stable and it is levelled,
- if the balance is exposed on rapid air blasts, vibrations, rapid temperature
changes or air humidity,
- if the balance is not affected directly by heat source, electromagnetic radiation
or magnetic field.
The cause of inaccuracy can be too low temperature of the balance as well, when it
was unplugged from power supply. In this situation leave the bal ance switched on for
several minutes in order to adjust its internal temperature.
If none of above causes of inaccuracy occurs, calibration with external weight should
be performed to the balance. Recommended external calibration weight (to buy for
additional charge) is given in technical data table. In order to calibrate the balance with
external weight in legally verified balances verification seals should be removed and
another legal verification should be performed. In this case it is recommended to
contact authorized service centre.
Calibration with external weight is described in details in chapter 15.7.

Case
When cooperating with a computer, the scale
sends weighing result after initialising signal
from a computer or after pressing key on
the scale.
For cooperation with the scale a computer
should be equipped with software allowing
receiving data from the scale and using it
further.
- Communication – free program for sending simple commands to the scale and
receiving weighing results,
- ProCell – program for cooperation with Microsoft EXCEL and other Microsoft
Windows applications (demo version).
Three modes of work serial connections are possible:
- standard mode (stb - with stabilization of indicator or without)
- automatic mode (auto)
- continuous mode (Cont.)
Special function (SErIAL) is serve to choice a type of work serial connector (see
below).
Standard type.
Scale sends result of weighting on an initialize signal from computer, or after pressed
key.
Automatic mode (this mode can be use to cooperation with a printer)
Data are send automatically after result stabilization, but next transmission is possible
after removing previously weighted sample. Data contains next number of sample and
result of weighting.
Continuous mode.
Scale sends result of weighting on each 0,1 seconds.
