7. Preparing working environment

+18°C

+33°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.

10 USER MANUAL

__________________________________________________________________________________________________________________

8. Preparing scale to work

1. Take the scale and feeder out of the
package. It is recommended to keep the
original scale package in order to transport
the balance safely in future.

2. Place the scale on a stable ground not
affected by mechanical vibrations and
airflows.

3. Level the scale using rotating legs 6 so
that the air bubble in water level 7 at the back
of the scale is in the middle.

4. Put draft shield 8 on the scale and cover 9

on it.

Scale should be transported in the way, that there is no risk of accidental pressing or
overweighing a pan.

If the scale was taken from a lower temperature surrounding to a room with higher

temperature, e.g. in winter, moisture can liquefy on the scale casing. Do not connect power

supply to the scale, because this can cause damage or improper work of the scale. In this
case leave the scale for at least 4 hours unplugged for acclimatization.

USER MANUAL 11

__________________________________________________________________________________________________________________

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 known 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.

12 USER MANUAL

__________________________________________________________________________________________________________________

10. Internal calibration

The ATA balances are equipped with internal calibration system, which general task is to maintain
required measurement accuracy.
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 1oC).

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 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.

USER MANUAL 13

__________________________________________________________________________________________________________________

Note:

In order to terminate internal calibration process in balances that do not comply with verification
requirements press key and wait until balance mechanism is settled in initial position.

11. 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.

14 USER MANUAL

12. Connection with a computer or a printer

The scale is equipped with RS232C, which can be used to connect external devices such as computer
or a printer.

When cooperating with computer, the scale sends weighing result after initialize signal from computer or
after pressing key on the scale.

When cooperating with a printer data is send automatically after result stabilisation, but next transmission
is possible after removing previously weighted sample.

When cooperating with label printer after pressing key, the scale sends instructions set for the label
printer. Label number 0001, hour, data (if the clock is installed and on) and nett weight. During
transmission LabEL communicate is displayed.
The way of sending data and transmission parameters is set using SErIAL special function.

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).

If the scale is equipped with two serial joints Print function is set independently for both interfaces.

Computer must have a special program for cooperation with data from a scale.
Dedicated programs are also offered by AXIS.

Except RS232C joint, the scale can be equipped with USB or Wi-Fi interface.
Needed controllers and instruction can be found on a CD supplied with Axis scales.
