DEFINITION

Classification: 73/1.01

INSTRUMENT PROVING OR CALIBRATING:

(under the class definition) Subject matter comprising a process or an apparatus for (a) ascertaining (i.e., proving) the quality of a measuring device, a testing device, or a condition responsive device by testing the respective device, or (b) checking, adjusting, or standardizing systematically (i.e., calibrating) the graduations of a quantitative measuring instrument or a condition responsive device (e.g., sensors, safety valves, etc.).

(1) Note. Where the proving or calibrating is by measuring means or testing means of a kind provided for in another measuring or testing class, the subject matter is found in the other measuring or testing class. See such measuring or

testing class and the Lines With Other Classes to this class definition.

(2) Note. Where more structure of a measuring device, a testing device, or a condition responsive device is recited than that which is necessary to (a) prove or calibrate or (b) identify the measuring device, the testing device, or the condition responsive device, the subject matter goes with the analyzer or the condition responsive device.
