Advantages and Disadvantage of Digital Instruments

Advantages and Disadvantage of Digital Instruments Points : Advantages and Disadvantage of Digital Instruments Advantages i. As digital meters indicate the reading directly in decimal numbers and therefore errors on account of human factors like errors due to parallax and approximation are eliminated.
ii. The reading may be carried to any number of significant figures by merely positioning the decimal point.
iii. Since the output of digital instruments is in digital form and therefore the output may be directly fed into memory devices like printers and digital computers etc. for storage and for further computations.
iv. The power requirements of digital instruments are considerably smaller.
v. There some applications where only digital instruments can be used. Disadvantage i. The sampling rate of digital meters is 1 to 5 readings per second, which
is very low, therefore, they can not show sudden changes in the value.
ii. Their constructions is complex.
iii. These are expensive and affected by temperature changes and moisture.
iv. Mechanically these are weak.
v. Their repair and maintenance cost is high.
vi. These show discontinuous operation.
