To deal with this use, we need to remember some definitions. In deed, the correct technical term to define the TITRIVIN use is adjustment of a measuring system instead of “calibration”.

According to the International vocabulary of metrology – Basic and general concepts and associated terms, the definitions are :

Definition of calibration

The calibration is a “operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement indications with associated measurement uncertainties standards and corresponding and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication”.

A step of calibration consist in :

• measuring a quantity with a equipment to calibrate and a measurement standard equipment at the same time,
• comparing the two equipment’s indications,
• exploiting the results of this comparison.

The results of the calibration have to allow the laboratory to attribute to the indications the standard values and/or to determine the corrections to apply to these indications.

Calibration should not be confused with adjustment of a measuring system.

Definition of adjustment of a measuring system

The adjustment is a “set of operations carried out on a measuring system so that it provides rescribed indications corresponding to given values of a quantity to be measured”.

This operation could be realized with our TITRIVIN products.

As, for a given parameter, the reference value of a TITRIVIN has an uncertainty (u) , you could use a value within to the confidence interval [Vref – u ; Vref + u] to improve your adjustment.
