1. General description
AGN…C series balances are destined for high accuracy weighing in laboratory
practice. Balances are equipped with internal calibration system for accuracy
control during balance operations.
All balances are metrologically tested. According to an order balances can be
calibrated or legally verified.
Balances with legal verification comply with certificate of type approval and are
marked with the following legal and securing items:
-green metrological mark placed on the balance name plate,
-notified body stamp (number of notified body) on the balance name plate,
-protective seals placed on: an edge of balance name plate, the casing mounting
screw and in the place of access to adjustment switch,
In order to renew legal verification please contact authorized service of AXIS.
Balance classification according to PKWiU: 33.20.31.

3. Safety rules
It is necessary to follow safety rules of work with the
balance shown below. Obeying those rules is the
condition to avoid electrical shock or damage of the
balance or connected peripheral devices.
Repairs and necessary regulations can be done by authorised personnel
only.
To avoid fire risk use a feeder of an appropriate type (supplied with the
balance) and supply voltage have to be compatible with specified
technical data.
Do not use the balance when its cover is opened.
Do not use the balance in explosive conditions.
Do not use the balance in high humidity environment.
If the balance 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 balances should not be put
into waste containers together with ordinary waste.
Wasted balance 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
+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.

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.
