Calibration
4. Calibration
Your balance can be calibrated with an internal mass (optional) or external masses. The balance can also be
checked by a test with internal or external masses. If you have a printer attached to your balance, the data of the
calibration and the results are printed out following GLP recommendations. A choice of six calibration methods are
available: Span, Linearity, User, Test, Automatic AutoCal
TM and AutoCal TM with Delta Correction.

Span - Span calibration ensures that the balance reads correctly
within specifications using two weight values: zero and a
weight value at 100% of the balance’s full capacity.
Linearity - Linearity calibration minimizes deviation between actual
and displayed weights within the balance’s weighing
range. Three weight values are used: zero, a weight
value at midpoint of the balances weighing range, and a
weight value at or near the balance’s specified capacity.
User- User calibration is a method where the balance can be
calibrated using a mass of known value by entering that
value into the balance.
Test- Calibration test allows the stored calibration data to be
tested against the current mass being used for the test.
AutoCal TM On balances equipped with AutoCal TM, automatic calibra-
tion of the balance is accomplished by an internal mass.
AutoCal TM On balances equipped AutoCal TM , a software feature
W/Delta allows the internal calibration mass to be adjusted ± 100
Correction divisions at full scale capacity. This permits adjusting
the balance using an external Class I mass which is
traceable to a certified standard.
