A method and device, including a portable embodiment, for the automated inspection of devices having different visual changeable and non-changeable indicia on the faces thereof. Specific devices include meters, particularly electric usage meters, for detection of tampering, for improving efficiency of maintenance procedures and for usage in reading the meters for billing purposes. Meters of various heights, configuration and construction are fixed into designated positions and are inspected by visual computer-linked camera scanning, to determine meter periphery and a location reference point, and imaging of identifying portions of meter faces relative to the determined location reference point. The identifying portions are compared with correlative templates of existing meter types, stored in computer memory. Identification of specific meter type permits exact location and subsequent OCR identification of the specific meter number (with use history) and parameters (voltage, amperage, wire connections etc.) for preparation of an operability-inspection station. Meter dial needle positions are read by light scanning of respective determined dial positions, and imaging of connected dark pixels, indicating needle location. A slope determination fixes the reading of the dial, which is used for billing purposes. Adjacent dial needles are in a predetermined relative position with deviations therefrom indicating tampering. Numeral meter readings are OCR scanned for billing purposes.
