Span Calibration
Note
Using a verified balance as a legal measuring instrument in using region:
Span calibration must be performed once the balance is installed and before
using the balance as a legal measuring instrument in using region. Span
calibration must be performed with the internal calibration weight to
maintain the verification valid. The balance must be connected to power and
warmed up for at least 2 hours prior to span calibration and use as a legal
measuring instrument.
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
temperature is constant, that there are no breezes or vibrations and that the balance is in an area isolated
from the normal traffic flow.
Note
When carrying out span calibration, it is necessary to make sure the balance
is as stable as possible. In order to ensure this stability, turn the power to the
g display for at least 1 hour and allow the temperature of the balance to
stabilize after installation, before carrying out calibration.
