Portable Advanced balances can be calibrated in two ways: Span calibration or
Linearity calibration. Span calibration resets the balance’s weighing range using two
points: zero and a calibrated mass value at or near the balance’s capacity. Linearity
calibration minimizes deviation between actual and displayed weights within the
balance’s weighing range using three points: zero, a calibrated mass value within the
balances weighing range, and a value at or near the balance’s specified capacity. The
illustration below indicates the sequence in which submenus appear on the Calibration
menu.

Before beginning calibration, make sure
calibrated masses are on hand. If you
begin calibration and realize masses are
not available, either turn the balance off, or
go through the procedure without masses.
The balance will use previously stored
calibration data. Calibration should be
performed as necessary to ensure accu-
rate weighing. Masses required to per-
form the procedures are listed in the adja-
cent table.
