Question

What is the range of comparator in bench micrometer with dial comparator?

(a) ±50 µm

(b) ±100 µm

(c) ±150 µm

(d) ±200 µm

I have been asked this question at a job interview.

Asked question is from Bench Micrometer topic in division Linear Measurements of Engineering Metrology

Answer 1

Correct answer is (a) ±50 µm

For explanation I would say: Range of bench micrometer and comparator in bench micrometer with dial comparator is 0-25 mm and ±50 µm respectively.
