7. Preparing working environment
+18°C
+33°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.

10 USER MANUAL
____________________________________________________________________________________________________________________
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 7
at the back of the balance is
in the middle.
4. (for AG100-AG600) Gently
insert the mandrel of pan
support 2into balance
mechanism socket through
the pan ring 3 and the pan 1
on (AG600 balances have
not the pan ring).
5. (for AG1000-AG4000)
Place nuts 2on mandrels
that are visible in balance
cover holes, put the pan 1
on nuts.
6. 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.

USER MANUAL 11
____________________________________________________________________________________________________________________
9. General operation principles
1. After each location change user should level the balance and perform internal calibration.
2. Weighed sample should be placed in the centre of the pan.
3. Weighing result should be read when the indicator " " lights, which signalises stabilisation of a result.
4. 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.
5. 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.
6. 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.
7. The balance cannot be used to weigh ferromagnetic materials due to decrease of weighing accuracy.
8. Balance mechanism is a precise device sensitive to mechanical shocks and strokes.
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.

12 USER MANUAL
____________________________________________________________________________________________________________________
10. Start-up
Plug feeder into 230V power supply socket and feeder output connector into 12V socket at back of the
balance.
After switching-on, the balance displays AXIS logo
and performs automatic self-tests.
In case of test failure balance displays tests list. Lack
of mark means negative test result.
Afterwards the balance enters automatically into
internal calibration mode, which is described with
details in next chapter. Calibration can be terminated
using CLR key.
When internal calibration is finished, the balance
enters into normal weighing mode.
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,
-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 press CLR key
and wait until balance mechanism is not settled in

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 17.1.
13. Connecting the balance to computer or printer
The scale can be equipped with one or two serial interfaces RS232C, USB, LAN or Wi-Fi designed to
cooperate:
-with computer –the scale sends data after pressing key or after initiation signal from
computer,
-with printer - sending data after pressing key or automatically after putting on/off a sample
and measurement stabilization,
-with label printer –after pressing the scale sends set of instructions for label printer starting
from label number set in special funcion LabEL.
Set of send data is set using special function PrInt.
The following data can be send:
-Header (scale type, Max, d, e, serial number),
-Operator identification number,
-Successive printout number (measurement),
-Identification number or product bar code,
-Number of pcs (PCS function only),
-Single detail mass (PCS function only),
-Nett weight,
-Tare (package mass),
-Gross weight,
-Total mass (Total function only).
The way of sending data and transmission parameters is set using SErIAL special function.

USER MANUAL 15
____________________________________________________________________________________________________________________
If the scale is equipped with two serial joints (interfaces) Print and SErIAL function is set independently for
both interfaces.
If scale cooperates with a computer then the computer must have a special program. Dedicated programs
are also offered by AXIS.
Needed drivers and instructions can be found on the CD supplied with Axis scales.

15.2 Calibration with external weight / calibration options
Calibration with external weight should be performed if balance accuracy after internal calibration is not
satisfactory. Calibration weight stated in technical data table for the balance (or of better accuracy) with
valid verification certificate should be used then.
Calibration of legally verified balance requires violating a mark used to protect an access to
adjustment switch and results in loosing legal verification. To renew legal verification of the
balance, it is necessary to contact a service or notified body.
In balances comply with verification requirements performing calibration requires changing adjustment
switch position, which is placed behind protecting mark (sticker) of a notified body. An access to the switch
is possible only after removing the mark.
Before proceeding with calibration for balances comply with verification requirements, adjustment switch
should be set to ON position using thin screwdriver (the balance will display the message Pr ON).
When calibration process, described on next page, is finished, the balance will display the message Pr ON.
Adjustment switch should be set to OFF position using thin screwdriver (the balance will move to weighing).
