1. General description
AKA/AKZ series balances are destined for high accuracy weighing in laboratory practice.
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.
Certificates:

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
+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.
