Horizontal Video Caliper, Video Based Measurement
Video Micrometer, Video Scaler
Now Available for High-Definition!
The Model 307 Video Caliper, Video Micrometer, Video Based Image Measurement Device is ideal for measuring
blood vessel diameter, along with video measurement & marking. The unit provides the means to take horizontal
measurements of objects in a real-time video image.
The Video Caliper, Video Micrometer, Video Based Image Measurement Device 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.
