DEFINITION

Classification: 324/133

(under subclass 76) Subject matter for giving a nonquantitative indication.

(1) Note. This subclass includes, for example, polarity testers and "hot-line" indicators.

(2) Note. A quantitative instrument may be modified into a nonquantitative instrument by merely omitting the scale. Consequently, in appropriate instances, the search should extend to the pertinent quantitative type subclass.
