Question

Accuracy of a potentiometric DVM is ________

(a) zero

(b) medium

(c) low

(d) high

This question was posed to me in examination.

Enquiry is from Potentiometric Integrating Type DVM in chapter Electronic Instruments of Electrical Measurements

Answer 1

Correct option is (d) high

For explanation I would say: In a potentiometric integrating type DVM, the accuracy is usually high. It generally depends on the reference of the digital to analog converter. Accuracy of the voltage to frequency converter is less important compared to that of the digital to analog converter.
