Standarder

Overholdelse af standarder i enhver branche er afgørende for periodisk at kontrollere nøjagtigheden af udstyr. Ved at sammenligne med kendte værdier kan outputmålinger afsløre fejl og informere personalet om nødvendige justeringer. Når indstillingerne for manuelle eller automatiske instrumenter er nulstillet, vil de genoprettede forhold give optimal ydeevne. Kalibrering med koncentrerede standarder eliminerer risikoen for, at miljøændringer forårsager instrumentfejl, når præcision er mest afgørende.
