Precision Advanced balances features CalTest TM which offers a choice of three
calibration methods: Cal Span, Cal Linearity, and Cal User. Cal Span Cal Span Cal Span Cal Span Cal Span calibration
ensures that the balance reads correctly within specifications using two weight
values: zero and a weight value at either 25%, 50%, 75% of or at the balance’s full
capacity.
Cal Linearity Cal Linearity Cal Linearity Cal Linearity Cal 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.
Cal User Cal User Cal User Cal User Cal User is a method where the balance can be
calibrated using a mass of known value by entering that value into the balance. Cal Cal Cal Cal Cal
Test Test Test Test Test allows the stored calibration data to be tested against the current mass being
used for the test. The following figure illustrates the sequence in which submenus
appear on the Calibration menu. Item shown bolded is a default setting.

NOTES NOTES NOTES NOTES NOTES:
1. Calibration may be locked out to pre-
vent unauthorized personnel from chang-
ing calibration. If calibration has been
locked out, you can only access Cal Test.
2. To lock out calibration menu, after
calibration, refer to the section titled Menu
Lock-Out Protection.

Before beginning calibration, make sure
masses are available. If you begin cali-
bration and realize calibration masses are
not available, exit the menu. The balance
will retain previously stored calibration
data. Calibration should be performed as
necessary to ensure accurate weighing.
Masses required to perform the proce-
dures are listed in the adjacent table.
