Definitions

from The American Heritage® Dictionary of the English Language, 5th Edition.

  • noun A device that records oscillations, as of an electric current and voltage.

from The Century Dictionary.

  • noun An instrument for recording alternating-current wave-forms and for the study of electrical oscillations.
  • noun An apparatus for recording graphically the motions of oscillation of any structure or element as to frequency and magnitude. The element may carry a pen or tracing-point, while a paper, borne on a fixed support, is moved before the tracer as the latter oscillates; or the principle may be reversed: used to record the effect of trains on bridges, or of moving machinery in buildings, or the effect of earth-movements on structures.

  • noun a device for making a record of the wave forms of fluctuating .
  • noun (Elec.) An apparatus for recording or indicating alternating-current wave forms or other electrical oscillations, especially of voltages or currents; it usually consists of a galvanometer with strong field, in which the mass of the moving part is very small and frequency of vibration very high.
