MEASURING NOT SPECIALLY ADAPTED FOR A SPECIFIC VARIABLE; ARRANGEMENTS FOR MEASURING TWO OR MORE VARIABLES NOT COVERED BY A SINGLE OTHER SUBCLASS; TARIFF METERING APPARATUS; MEASURING OR TESTING NOT OTHERWISE PROVIDED FOR (means structurally associated with lightning or other overvoltage discharging apparatus for recording the operation thereof G 01 R; displaying information in general G 09 F; recording in a way which requires playback through a transducer G 11 B)

Indicating measured values

Indicating value of two or more variables simultaneously

using a separate indicating element for each variable

Luminous indications projected on a common screen

using a common indicating element for two or more variables

giving indication in co-ordinate form

Audible indication of meter readings, e.g. for the blind [2]

Recording measured values

Producing one or more recordings of the values of a single variable

with provision for multiple or alternative recording

Multiple recording, e.g. duplicating

giving both graphical and numerical recording

the recording element, e.g. stylus, being controlled in accordance with the variable, and the recording medium, e.g. paper roll, being controlled in accordance with time

recording occurring continuously

with provision for altering speed of recording medium in accordance with the magnitude of the variable to be recorded

recording occurring at separated intervals, e.g. by chopper bar

recording element actuated only upon change in value of variable

the recording element, e.g. stylus, being controlled in accordance with time and the recording medium, e.g. paper roll, being controlled in accordance with the variable

recording occurring continuously

recording occurring at separated intervals, e.g. by chopper bar

either the recording element, e.g. stylus, or the recording medium, e.g. paper roll, being controlled in accordance with both time and the variable

Producing one or more recordings, each recording being of the values of two or more different variables (G 01 D 9/38, G 01 D 9/40 take precedence)

there being a separate recording element for each variable, e.g. multiple-pen recorder

there being a common recording element for two or more variables

the variables being recorded in predetermined sequence

in separate columns

Producing one or more recordings, each recording being produced by controlling the recording element, e.g. stylus, in accordance with one variable and controlling the recording medium, e.g. paper roll, in accordance with another variable

Producing one or more recordings, each recording being produced by controlling either the recording element, e.g. stylus, or the recording medium, e.g. paper roll, in accordance with two or more variables
