4.5 Span Calibration
It is necessary to calibrate the balance after it is moved.
Verify that the balance is stable before performing the span calibration. To achieve a very stable state,
ensure that the balance has been turned on with the gram-display for at least one hour, that the tem-
perature is constant, that there are no breezes or vibrations and that the balance is in an area isolated
from the normal traffic flow.
