Horizontal Video Caliper, Video Based Image Measurement, Video Micrometer, Video Scaler        Model 307 The Model 307 Video Caliper, Video Micrometer, Video Scaler, Video Based Image Measurement device for video image measurement & video marking, provides the means to take horizontal measurements of objects in a real-time video image. The Video Caliper, Video Micrometer, Video Base Image Measurement Device, Video Inspection Instrument, Video Scaler superimposes two vertical cursors onto the video display. The user can adjust the position of these cursors by means of front panel controls. The right-most control sets the distance between the cursors by moving the right cursor only. The left control moves both cursors across the screen while maintaining the distance between them. This arrangement allows dimensional comparison of objects across the image without disturbing the distance between the cursors. A 4 digit display indicates the distance. Three scale adjustment controls calibrate the meter reading for a given distance between the cursors. A switch allows the user to select between the three control settings so that calibrations can be made and then selected as necessary for three different optical setups. These calibrations must be made any time the optics or distance between the image sensor and the object under scrutiny change. These controls require a small screw driver for adjustment in order to avoid inadvertent disturbence of the calibration. The cursors can be set to white, black, or off. Power input requirement is 9 VAC at about 150 mA. An AC adapter is included. The adapter is UL listed for safety and isolates the model 307 from ground in order to avoid interference inducing ground-loops.   PDF Data Sheet      Description       Application Notes      Online Ordering & Prices    Specifications Model: All Models of Video Caliper, Video Micrometer, Video Based Image Measurement Device Size: 6.9"W x 4.9"L x 2.4"H sloping to 1.4"H Mounting: Free standing desktop Power Connector: 0.125" mini-phone power jack Power Input: 9 VAC (120 VAC Adaptor included where appropriate) Chassis: Black ABS Video Input/Output: 1Vp-p, composite, 75 ohm (s-video optional) Options: PAL Video, S-Video, Analog Dimension Output I/O Connectors: BNC (4-pin mini-DIN for s-video) Controls Decimal (switch): Selects Decimal Display Position Lines (switch): Selects Off, Black, or White Calibrate (3)(pontiometers): Calibrates Display to Known Reference Controls Calibration (switch): Selects Between 3 Different Calibration Potentiometers Model: 307: Video Caliper, Video Micrometer, Video Based Image Measurement Controls Position (Single-turn potentiometer): Moves Both Cursors Distance (Single-turn potentiometer): Moves Only Right Cursor Model: 307A: Video Caliper, Video Micrometer, Video Based Image Measurement Controls Position (Ten-turn potentiometer): Moves Both Cursors Distance (Ten-turn potentiometer): Moves Only Right Cursor   PDF Data Sheet      Description       Application Notes      Online Ordering & Prices       PO Box 928    Boulder, CO 80306 USA    Tel +1-303-530-9580    sales@colorado-video.com    Fax +1-303-530-9569    Business Hours: 9AM to 4PM Mountain Time (GMT-7 Winter, GMT-6 Summer), excluding weekends & holidays. www.colorado-video.com Copyright 2004-2008   Colorado Video, Inc.
