Question 241General Subjects - QMED

The correct answer is C) measure wire diameter. The illustration GS-0079 appears to depict a micrometer, which is a precision instrument used to measure the diameter or thickness of small objects, such as wire. Micrometers are a common tool used by mariners and engineers to accurately measure the dimensions of various components, including wiring used on vessels. The other answer choices are incorrect because they do not accurately describe the primary function of a micrometer. Gaging resistors, stripping insulation, and measuring insulation thickness are not the intended purposes of this instrument.
