The Video Caliper superimposes two vertical, horizontal, or diagonal, cursor lines, or two cursor points onto the video display. The user can adjust the position and rotation of these cursors by means of front panel controls. In most modes, one control sets the distance or angle between the cursors by moving one cursor only. The second control moves both cursors across the screen while maintaining the distance and angle between them. This arrangement allows comparison of objects across the image without disturbing the relationship between the cursors. An on-screen display, of adjustable size and position indicates the measurement in a variety of selectable units. The cursors can be individually set to a variety of colors, and provide adjustable width and intensity/transparancy.
Four separate dimensional calibrations can be stored for easy recall and use. Units are automatically converted in order to preserve calibration if they are changed. For instance, calibration can be made in inches and readings taken in centimeters. Calibration or calibration reselection must be made any time the optics or distance between the image sensor and the object under scrutiny change.
Power input requirement is 5 VDC at at less than 1 Amp. A UL listed AC adapter is included.
