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.
•
Calibration Test
- Calibration test allows the stored calibration data to be tested against the current mass being
used for the test.
•
AutoCal
TM
Automatic calibration (AutoCalTM) of the balance is accomplished by an internal mass.
Calibration Menu Protection
NOTES:
• Calibration may be locked out to prevent unauthorized personnel
from changing calibration. If calibration has been locked out,
you can only access Internal Weight Calibration and Calibration
Test.
•To lock out calibration menu, after calibration, refer to the section
titled Menu Lock-Out Protection.
• Linearity, Span and User calibration are disabled for Type
Approved/LFT balances.
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 the adjacent table.
