The major advantage of a digital display is that it eliminates parallax errors and reduces the human errors associated with interpreting the position of a pointer on an analogue scale.

Comparison Methods, than direct measurements; for example, by using a detector that has a resolution of a microvolt it is possible to compare in terms of microvolts two voltages that have magnitudes of the order of, say, 1 V. The accuracy of such methods must, however, depend on the limits of error that apply to the ‘known’ or ‘standard’ quantity used.

Instrument Selection and Specification Analysis,s a prestige exercise. This is of little value if within a week, justifiable pressure is brought to bear by one’s colleagues and the prestige instrumentation system is reduced to its minimum requirements— which could be two suspect multimeters and the oldest oscilloscope in the department!

https://doi.org/10.1007/978-3-662-26064-7relate this definition to practical terms means that any use of instruments constitutes an instrumentation system, since a suitable instrument or chain of instruments will always convert an unknown quantity into a record or display which human faculties can interpret.
