Question 505General Subjects - Assistant Engineer
70% to passThe purpose of the instrument illustrated is to _______________. Illustration GS-0079

Astrip insulation from wire
Bgage resistors
Cmeasure wire diameter
Dmeasure insulation thickness
AI Explanation
The correct answer is C) measure wire diameter. The illustration GS-0079 appears to show a micrometer, which is a precision instrument used to measure the diameter or thickness of objects, including wire. Micrometers are a common tool used in the maritime industry, including by the US Coast Guard, to accurately measure wire and cable dimensions as part of maintenance, repair, and safety inspections. The other answer choices are incorrect because: A) stripping insulation is done with a wire stripper, not a micrometer; B) gaging resistors is not a common application of a micrometer; and D) measuring insulation thickness is not the primary purpose of the micrometer shown in the illustration.
