Standard
Il rispetto degli standard in qualsiasi settore è essenziale per verificare periodicamente l’accuratezza delle apparecchiature. Confrontando i valori misurati con quelli noti, le letture individuano eventuali errori e informano il personale sugli aggiustamenti necessari. Una volta che le impostazioni degli strumenti manuali o automatici vengono riportate a zero, le condizioni ristabilite garantiscono prestazioni ottimali. La calibrazione con standard concentrati elimina la possibilità che i cambiamenti ambientali causino errori strumentali quando la precisione è più importante.
