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.

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 2
o
C).
In legally verified balances time interval is set to 2 hours and defined
temperature change is 2
o
C. 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.
