Multiple Choice

The precision measuring tool you cannot adjust to compensate for wear on the measuring surfaces is

Wear on measuring surfaces changes accuracy, and whether you can compensate depends on the instrument’s design. Some tools are built to be recalibrated or have replaceable contact surfaces to offset wear, while others don’t. A caliper uses sliding jaws that contact the part being measured. As those jaws wear, the gap they establish can drift, and there isn’t a straightforward adjustment built into the caliper to offset that wear without replacing or reshaping the jaws or the whole tool. That makes wear more difficult to compensate for compared with other instruments. In contrast, tools like micrometers and dial indicators are designed to be recalibrated or have interchangeable contact surfaces, so you can account for wear by zeroing against a standard or swapping tips. A ruler is a fixed scale with no adjustable features, so it cannot compensate for wear at all. Hence, the tool you cannot adjust to compensate for wear on the measuring surfaces is the caliper.
