Minebea Intec CAS-SPC Series - Calibration and Adjustment; Calibration and Adjustment Procedures; Configuration for Legal Metrology Use

Calibration, Adjustment
Purpose Perform calibration to determine the dierence between the value displayed and
the actual weight on the platform. Calibration does not entail making any changes
within the weighing equipment.
During adjustment, the dierence between the measured value displayed and the
true weight of a sample is corrected, or is reduced to an allowable level within
maximum permissible error limits.
Conguration for Use in Legal Metrology
Conguration of the weighing instrument for use in legal metrology is set by a
switch. The switch is located on the back of the weighing platform and covered by

– External adjustment is only possible by removing the seal. If the seal is broken,
the validity of verication will become void and you must have your scale
re-veried.
