Standarder
Att uppfylla standarder inom alla branscher är avgörande för att regelbundet kontrollera noggrannheten hos utrustning. Genom att jämföra med kända värden kan mätresultaten identifiera fel och informera personalen om att justeringar behövs. När inställningarna på manuella eller automatiska instrument har återställts till noll, kommer de återställda förhållandena att ge optimal prestanda. Kalibrering med koncentrerade standarder eliminerar risken för att miljöförändringar orsakar instrumentfel när noggrannhet är som viktigast.
