Claim:
1. A measurement device comprising: a housing adapted to be hand-held by a user; an infrared imaging module adapted to capture an infrared image of at least a portion of a work site; a logic device adapted to determine an electrical parameter associated with an external article and convert the captured infrared image into a user-viewable image for viewing by the user; a display screen fixed relative to the housing and adapted to display both the user-viewable image and information indicative of the determined electrical parameter; and a memory adapted to store one or more previous electrical parameters and its corresponding infrared image captured by the infrared imaging module, wherein the logic device is adapted to overlay the information indicative of the determined electrical parameter onto the user-viewable image to present both the user-viewable image and the information indicative of the determined electrical parameter on the display screen, or is adapted to switch between the information indicative of the determined electrical parameter and the user-viewable image, in response to a user input, to present both the user-viewable image and the information indicative of the determined electrical parameter on the display screen, and wherein the logic device is further adapted to recall the stored one or more previous electrical parameters to present, on the display screen, both current and previous electrical parameters overlaid on a currently captured infrared image of at least a portion of the same worksite as the one stored in the memory.
