CALIBRATION MENU

The Model AS60C Analytical Standard balance can be calibrated in two ways: Span
calibration or Linearity calibration. Span calibration resets the balance’s weighing
range using two weight values: zero and a weight value at or near the balance’s
capacity. Linearity calibration minimizes deviation between actual and displayed
weights within the balance’s weighing range. Three weight values are used: zero, a
weight value within the balances weighing range, and a weight value at or near the
balance’s specified capacity. The following table shows the sequence in which
submenus appear on the Calibration menu.

Calibration Menu Protection

Calibration may be locked out to prevent
unauthorized personnel from changing
calibration. To lock out calibration menu,
refer to the section titled Menu Lock-Out
Protection.

NOTE

NOTE: If calibration has been locked out,
you will not be able to access it.

Calibration Masses

Before beginning calibration, make sure
masses are on hand. If you begin calibra-
tion and realize masses are not available,
either turn the balance off, or go through
the procedure without masses. The bal-
ance will use 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.
