What's the difference between electrometer and precision?
Electrometer
Definition:
(n.) An instrument for measuring the quantity or intensity of electricity; also, sometimes, and less properly, applied to an instrument which indicates the presence of electricity (usually called an electroscope).

Precision
Definition:
(n.) The quality or state of being precise; exact limitation; exactness; accuracy; strict conformity to a rule or a standard; definiteness.
Example Sentences:
(1) A progressively more precise approach to identifying affected individuals involves measuring body weight and height, then energy intake (or expenditure) and finally the basal metabolic rate (BMR).
