10. 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.
11. 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.
In order to perform internal calibration proceed with the following:
