4.2.2 Calibration
To verify that the Balance is functioning properly, it must be calibrated prior to testing. At this point, the Balance
should have the menus set up if functional. After calibration, proceed to Performance Tests, paragraph 4.2.3 for
Precision balances and paragraph 4.2.4 for Analytical balances.
Calibration can be affected by changes in location, temperature, or rough handling. Adventurer

balances 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 balance's weighing range and a weight value at or near the
balance's specified capacity.
4.2.2.1 Calibration Masses
Before beginning calibration, make sure masses are available. If you begin calibration 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 procedures are
listed in Table 4-1.
