Calibration defined

The term “calibration” can have quite a few different meanings.  Manufacturers will often use the term to describe the initial setting of an instrument to a known value or values.  It can mean to compare an instrument to a known standard and subsequently make adjustments to the instrument to more closely align its indication with the reference standard indication.

We use the term “calibration”, as defined by OIML V 2-200-2010 International Vocabulary of Metrology-Basic and General Concepts and Associated Terms (VIM), to mean:

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

There are a few notes that go along with that definition, the most important of which is

Calibration should not be confused with adjustment of a measuring system, often mistakenly called “self-calibration”, nor with verification of calibration. 

We perform calibration and when possible will adjustment your instrument to more closely align with our standards.  And as always and when possible, “As Found” readings are taken and reported before any adjustments are made.
