a tool that records oscillations, at the time of an electric powered existing and voltage.
a guitar for measuring alternating or varying electric energy in terms of current and current.
a device for making a record associated with the wave types of fluctuating .
An apparatus for recording or indicating alternating-current revolution kinds or other electrical oscillations, specifically of voltages or currents; it frequently comprises of a galvanometer with powerful area, where the mass regarding the going part is quite small and regularity of vibration high.
An instrument for tracking alternating-current wave-forms and for the study of electrical oscillations.
An apparatus for tracking graphically the movements of oscillation of every structure or factor concerning regularity and magnitude. The factor may carry a pen or tracing-point, while a paper, borne on a set help, is relocated ahead of the tracer once the latter oscillates; or even the principle might corrected: accustomed capture the result of trains on bridges, or of moving machinery in structures, and/or aftereffect of earth-movements on frameworks.
a computer device to make an archive of wave kinds of fluctuating voltages or currents
