(under subclass 76) Subject matter having plural inputs to the measuring means.
(1) Note. A single circuit can furnish plural inputs to the measuring means, since a single circuit can carry a voltage and a current independently of each other. Thus, the indented subclasses contain watt meters and volt-ampere meters of the type which are not found in subclasses above.
(2) Note. This subclass includes, for example, ratio meters and summation meters.

62+, for complete resistance measuring systems including, as a part thereof, ratio meters.

340, Communications: Electrical, 870.01+, for telemetering systems for indicating at a remote point the value of a local condition. Note subclasses 870.11+ where the condition at plural localities is sensed. Note subclasses 870.19+ where the value of the condition is coded into a pulse type code.
