7. Preparing working environment

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 11

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.

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
6 so that the air bubble in water level 7
at the back of the balance is in the
middle.

4. (for AGC100-AGC600) Gently insert
the mandrel of pan support 2 into
balance mechanism socket through the
pan ring 3 and the pan 1 on (AGC600
balances have not pan ring).

5. (for AGC1000-AGC4000, AGZ10C)
Place nuts 2 on mandrels that are visible
in balance cover holes, put the pan 1 on
nuts.

12 USER MANUAL

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.

____________________________________________________________________________________________________________________

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 zero indicator is displayed before sample is placed on the pan.

If not, press 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.

USER MANUAL 13

____________________________________________________________________________________________________________________

10. 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.

14 USER MANUAL

g

g

~45 seconds

____________________________________________________________________________________________________________________

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.

USER MANUAL 15

_________________________________________________________________________________________________________________

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.

12. 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.
