1 Introducing the IQS-12002B

Calibration System

The IQS-12002B Calibration System has been designed to calibrate, verify,

and adjust several types of devices. Some concept pertaining to the system

are described here:

³ Calibration is a set of operations that establish, under specified

conditions, the relationship between values of quantities indicated by a

measuring instrument (DUT) and the corresponding values realized by

standards.

³ Verification consists in comparing calibration results with established

limits. It is the confirmation that, through the explanation of a given

item and a provision of objective evidence, it fulfils specified

requirements.

³ Adjustment is the operation of bringing a measuring instrument into a

state of performance suitable for its use.

³ Uncertainty is the parameter that quantitatively characterizes the

dispersion of values that could be attributed to the measures.

Uncertainty is given with a specific level of confidence.

Note: Accuracy is the qualitative expression of the capacity of an instrument to

give results close to the true value.

Note: Precision is the closeness of agreement between quantity values obtained

by replicate measurements of a quantity under specified conditions.
