The markings on the probe are either engraved rings or colour coded bands. A screening probe for example has 3 or 4mm banded block markings whilst a Williams periodontal probe is more accurate with mm markings. Before using the probe, the operator should ensure that they know what the markings represent by comparing the probe to a ruler.
