7. Preparing working environment
+18°C
+30°C
Location for the balance should be chosen with care in order to limit influence of
the factors that can interrupt working balance. This location has to maintain proper
temperature for working balance and necessary space for its operating. The balance
should stay on stable table made of material that does not influence magnetically
on the balance.
Rapid air blasts, vibrations, dust, rapid temperature changes or air humidity over
75% are not allowed in balance surrounding. The balance should be far from heat
sources and devices emitting strong electromagnetic or magnetic fields.

USER MANUAL 9
____________________________________________________________________________________________________________________
8. Preparing balance to work
1. Take the balance, the feeder and
mechanical elements of the pan out.
It is recommended to keep the
original scale package in order to
transport the balance safely in
future.
2. Place the balance on a stable
ground not affected by mechanical
vibrations and airflows.
3. Level the balance with rotating legs
6so that the air bubble in water
level 7at the back of the balance is
in the middle.
4. Place tin 4of weighing chamber.
5. Place ring 3protecting the pan
against hit from a side.
6. Gently insert the mandrel of pan
support 2into balance mechanism
socket through the pan ring 3 and
the pan 1on
7. Take feeder off the box.
If the balance was taken from a lower temperature surrounding to a
room with higher temperature, e.g. in winter, moisture can liquefy on
the balance casing. Do not connect power supply to the balance,
because this can cause damage or improper work of the balance. In this
case leave the balance for at least 4 hours unplugged for
acclimatization.

9. General operation principles
1. Weighed sample should be placed in the centre of the pan.
2. Weighing result should be read when the indicator " " lights, which signalises
stabilisation of a result.
3. The balance allows tarring in the whole measuring range. To tare the balance
press  T  key (on the left or on the right). Tarring 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 pan load easier and to avoid crossing measurement
range, the balance has a load indicator calibrated 0÷100% Max.
4. In direct sale use (d=e), make sure that  0  zero indicator is displayed before
sample is placed on the pan. If not, press  0  key and wait until the balance is
zeroed and zero indicator appears. In other balances the key does not operate.
5. When the balance is not used but should be ready to work immediately, it can be
switched off by pressing I/key. The backlight of balance reading system is then
switched off and the balance enters into "standby" mode, in which the balance
maintains internal temperature and ability to start working with maximum
accuracy. Standby mode is signalled by the OFF indicator. To switch the balance
on press I/key.
6. The balance cannot be used to weigh ferromagnetic materials due to decrease of
weighing accuracy.
7. Balance mechanism is a precise device sensitive to mechanical shocks and
strokes.
8. After every change of balance position, level the balance and perform internal
calibration using key.
Do not overload the balance more than 20% of maximum capacity.
Do not press the pan with a hand.
For transportation take off the pan (move it gently and lift it up) and
pan support (lift it up) and protect from any damages.

USER MANUAL 11
____________________________________________________________________________________________________________________
10. Start-up
Plug feeder into 230V power supply socket. When the pan is empty plug feeder
output connector into 12V socket at back of the balance. Autotests and internal
calibration will be performed.
Steps after start-up of the balance:
Display test.
Tests of electronic components.
Test of internal calibration (engine
heard).
Internal calibration (in not legally
verified balances can be terminated
using key).
Displaying balance program version.
After zeroing the balance is ready to
weighing.
It is recommended before making measurements to wait until
internal temperature of balance stabilize. To accomplish that, the
balance should be turned on for more than 2 hours before
measurements. From the perspective of measurements accuracy
continuous balance operation is beneficial.
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.

12 USER MANUAL
____________________________________________________________________________________________________________________
Internal calibration is performed in the following situations:
- when key is pressed,
- after defined time interval (for legally verified balances - 2 hours),
- after temperature change (for legally verified balances –more than 2oC).
In legally verified balances time interval is set to 2 hours and defined temperature
change is 2oC. In not legally verified 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
put three times on and obtained
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 calibration
process in not legally verified
balances 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 balance 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 15.3.
13. Connecting the balance to computer or printer
The balance may send data to a computer or a printer via RS232C interface.
When cooperating with the balance, a
computer should be equipped with software
that allows receiving data from the balance.
AXIS offers computer software to cooperate
with balances, available on www.axis.pl
website. Free software for basic operations
with the balance can be found there.
The balance sends weighing result according to SEndInG option in function for
setting serial interface parameters (rS-232C):
after initialising signal from a computer,
automatically after loading a weight on a pan and result stabilisation (Auto),
after pressing key and result stabilisation (b.P Stb),
after pressing key and without result stabilisation (butt.P),
continuously about 10 times per second (cont.).
