Standardy
Spełnianie norm w każdej branży jest niezbędne do okresowego sprawdzania dokładności urządzeń. Porównanie z wartościami odniesienia pozwala wykryć błędy i poinformować personel o koniecznych korektach. Po przywróceniu ustawień ręcznych lub automatycznych przyrządów do zera, odtworzone warunki zapewniają optymalną wydajność pracy. Kalibracja przy użyciu skoncentrowanych standardów eliminuje ryzyko błędnych odczytów spowodowanych zmianami środowiskowymi w sytuacjach, gdy dokładność ma kluczowe znaczenie.
