Abstract
An electrical indicator device for providing simultaneous relatively coarse analog, and higher-resolution, digital readings of a particular electrical parameter, all in one instrument. The device includes a d'Arsonval meter movement which carries a pointer movable over a predetermined portion of a calibrated meter scale plate, and a liquid crystal display having multiple digits, each digit being constituted of multiple segments. The segments are disposed completely within the confines of the meter scale plate, but lie substantially completely outside of the said predetermined portion thereof. The display is driven or energized by a digital voltmeter having its terminals connected to receive and monitor the same parameter that is being measured by the d'Arsonval movement. The arrangement is such that the individual segments of the digital display are always completely visible regardless of the position which the pointer occupies with respect to the said predetermined portion of the scale plate.
