Which caliper feature is used to measure outside diameters?

External measurements on a caliper are taken with the outside jaws—the larger gripping surfaces that contact the exterior of the part. When you place the object between these jaws and close them until they just touch, the distance shown reads the outside dimension, such as the outside diameter. Inside jaws are for measuring the interior of holes, the depth rod measures depth, and the thimble is part of the readout/adjustment mechanism rather than the measuring contact. So the outside jaws are the feature used for measuring outside diameters.
