Question

Sensitivity of a successive approximation type DVM is given by which of the following relation?

(a) S = fsmin

(b) S = fsmin × R

(c) S = R

(d) S = ^fsmin ⁄ R

I had been asked this question in homework.

The origin of the question is Successive Approximation Type DVM in portion Electronic Instruments of Electrical Measurements

Answer 1

Correct choice is (b) S = fsmin × R

The best explanation: In a successive approximation type DVM, the sensitivity is given by the relation

S = fsmin × R

where, S is the sensitivity

            R is the resolution

            fsmin is the full scale reading when the range is minimum.
