standards
Het naleven van normen in elke sector is essentieel voor het periodiek controleren van de nauwkeurigheid van apparatuur. Door te vergelijken met bekende waarden detecteren meetresultaten fouten en informeren ze het personeel over noodzakelijke aanpassingen. Zodra de instellingen van handmatige of automatische instrumenten zijn teruggezet naar nul, zorgen de herstelde omstandigheden voor optimale prestaties. Kalibratie met geconcentreerde standaarden elimineert de mogelijkheid dat omgevingsveranderingen instrumentfouten veroorzaken op momenten dat precisie van het grootste belang is.
