VIA-170

Video Image Marker-Measurement System

Shown right is the XY measurement mode of the Via-170. Also shown is text and the time/date label. Click on the image for a larger view.

• Measures the horizontal (X) dimension, vertical (Y) dimension, horizontal-vertical (XY) dimension and diagonals (point-to-point).
• Calculates the angle when operators place two or more points to define each leg of an angle, even when the vertex is not in view. Users can turn on or off a graphic display of the angle as it is being measured.
• Measures the radius and circumference of a circle when operators place three or more points along the perimeter of a circular image. Users can turn on or off a graphic display of the circle as it is being measured.
• Statistics mode with mean, standard deviation, low reading, high reading and range for X, Y, XY, point-to-point, angle, radius, circumference and area measurements.
• Security menu which allows for marker overlay protect and calibration protect. With this protection enabled only password holder can alter marker overlays or calibration.
• Type text to label the video image. The text can be positioned anywhere in upper and lower case characters.
• Crosslines can be displayed in one of ten different line patterns. Crosslines can also have an open or closed intersection and can be auto-centered.
• Align mode allows users to move multiple markers in unison to use as a go/no go gage.
• Freehand draw or write over the video image in choice of three different line thicknesses with an optional light pen, mouse pen or mouse.
• Displays path length of freehand drawing as drawing takes place with an optional light pen, mouse pen or mouse.
• Calculates the area of a cell or shape when operators define the cell or shape.
• Measures elapsed time simultaneously with X, Y, XY and point-to-point measurement or independently.
• Measures the long and short chords of a cell or object when operators indicate the extremes of the perimeter.
• Offers a counting mode. Operators tag each cell or particle to be counted. Up to 10 different categories can be marked.
• Ten different pointers including arrows, standard cross hairs, a target circle, a small circle, a target box and a small box. 
• A sizeable and positionable reference circle or scale can be created for a quick comparison of objects or cells to a standard.
• Sizeable grids can overlay the video image to assist in counting.
• The current date and time may be displayed anywhere.
• Horizontal, vertical or diagonal lines may be positioned in one of three different line thicknesses.
• Store up to 10 pages of marker overlays from simple to complex.
• Up to 10 different calibrations may be stored for future use.
• RS-232 output so that users can transmit ASCII data of measurements and statistics to printers or computers.
• Markers and measurement lines may be displayed in up to three different colors or shades for optimal contrast with the video image (color markers will be displayed only if an optional VIA-RGB or VIA-Y/C interface is being used with RGB or Y/C monitors).
