The VMU series of video calipers from MicroImage Video Systems utilize extensive digital processing to maintain high accuracy and repeatability. Usable with most video cameras, the VMU800 provides fast, efficient and affordable non-contact measurement. Units are compatible with HDMI and DVI progressive video standards up to 1200p60.
The MicroImage VMU series of video measurement units are designed to be highly flexible and powerful, yet easy to use. Unlike analog based units, all mathematics are done digitally, allowing the VMU series to maintain consistent precision regardless of the scale factor. All lines are digitally rendered for solid, repeatable performance over time with virtually zero drift. High precision optical encoders are used for the position controls, eliminating jitter which can plague analog based measurement devices
Using the VMU series is easy. A size reference is placed in the field of view and the cursors are moved to the reference dimensions. The calibration value is entered on the keypad and can be set to the X or Y axis. This provides far more range and precision than using a rotary control to set calibration. From this point on, the unit is calibrated, provided the distance to the object or magnification (zoom) doesn’t change. Ten memories are provided to store multiple calibrations for different optics/magnifiers, saving significant time. The units remember all settings in non-volatile memory when turned off.
The coordinate display can be moved virtually anywhere on the screen. Any combination of x, y or diagonal measurements can be displayed at the same time. The color and background of the numeric display can be changed , as well as the color of each line. Any line can independently be turned off, displayed as solid, or serrated with many styles for maximum flexibility.
A number of additional features have been added to simplify day to day usage. Cursors may be moved fully independently or may be moved in pairs where one control moves both cursors on the same axis and the second control changes the spacing between them. Each control may be independently locked to avoid inadvertent adjustment. Controls can also be independently locked from within the menu system, regardless of the state of the lock button as further protection against accidental change. The lines may be displayed full screen or can be displayed as a box on screen. A front panel bypass switch allows the user to quickly turn the line and coordinate display off or on as needed.
All VMU series products can be powered from a +12VDC, negative ground power source. MicroImage Video Systems can provide board level product, private labeling or even custom functions. The units are based on a new MicroImage Video platform which is highly flexible and programmable. All units carry a one year parts and labor limited warranty.
At MicroImage Video Systems we incorporate suggestions from customers when possible. Several customers suggested password protection so that calibration settings could not be changed. We added this capability to all production units with several levels of password protection. It also has a programmable auto time out feature. In the event a key is not pressed within a certain amount of time, the protection is automatically re-enabled. This is important in case it becomes forgotten after a setting is changed. Password protection can also be disabled for easy access in a safe environment.
Rack mount units are not available for this product.
This unit is RoHS compliant.
The VMU800 is available packaged (cased) or as a board level product for OEM applications. Power is provided by a universal power supply (included with cased products) or it can be operated from +12VDC (negative ground). Board level products do not include the power supply and a 12VDC power source must be provided. The unit is packaged in a durable metal enclosure. Board Level, OEM and Custom products are also available. Please contact MicroImage Engineering for additional information.
The VMU800 has a one year parts and labor limited warranty.
