Description
An exemplar example First generation from 1890 Model 125"Edward Weston and the Weston Electrical Instrument Company introduced the first portable and direct-reading current and voltage meters in 1888-1893. Weston's inventions enabling these meters included: the first truly permanent magnets; temperature-insensitive conductors; low-resistance and non-magnetic springs; metal coil frames where induced eddy currents provided pointer damping (1887); the electric shunt (1893) for the measurement of large currents; and multiple current ranges in a single meter."
