Equipment On/Off Control and Electrical Connections AVR systems have two On/Off switches: one on the back right of the metrology unit right at the electrical connections, and one in the upper left of the all-in-one PC. Turn the system off when not in use.
There are no user adjustments or controls behind the hinged back. Optical Assemblies and Substage Illumination AVR200 and AVR300 configurations are available with manual 6.5:1 zoom optics with adjustable magnification from 0.47X to 3.0X, with motorized 12:1 zoom optics with adjustable magnification from 0.4X to 4.7X, or with any of six telecentric lenses with a fixed magnification of 0.30X, 0.50X,...

Safety personal injury and to maintain equipment calibration and measurement performance. Disconnect all power sources prior to moving or working on the equipment. Consult Starrett if you have any question regarding transporting, using or maintaining this system. Electrical AVR vision metrology systems do not contain hazardous AC line voltages, as these are contained on the input side of the system’s two AC adapters, which are UL listed.
AVR systems are designed to be installed on a benchtop at a height of approximately 85 cm (33.5”), which is the height of Starrett’s ergonomic workstation. A level work surface, as checked with a bubble level, is recommended, but is not essential. Allow 60 cm (24”) to right or left side of the metrology unit to position the all-in-one PC.

Removing Shipping Retainers AVR systems (and other Starrett metrology systems) use metal tabs to prevent movement of critical components during shipment. Anodized red for easy identification, these are intended to be removed once the equipment has been placed in its final position. Look for any red tabs and remove them.
Electrical Power System power supplies AVR systems are powered by two “brick” type AC adapters, one for the metrology unit (19.5 Vdc output) and one for the all-in-one PC (24 Vdc output). Both accept 100/240 Vac power for world- wide use. The maximum combined current draw is 4.6A at 120 Vac or 2.3A at 240 Vac. Make sure that the power outlet is rated for at least these currents.
Training is with the new equipment and is limited to 1 to 3 people, so that these can all get hands-on time. Starrett’s objective is to create “power users,” who can then train other users when needed.
1.5”). If the entire part cannot fit into the FOV, no problem. Simply move the stage by up to 200 mm (4”) for the AVR200 or 300 mm (12") for the AVR300, and the M3 software will seamlessly integrate FOV measurements with encoder readings from stage motion.
Focus Strategy Accurate measurement requires proper focus of the image. When measuring flat parts, always first ensure that the stage glass has been leveled. When using zoom optics, first focus the image at highest magnification, then decrease the magnification to the desired level. Parts Fixturing The part must be fixtured securely to prevent part movement during measurement.
Parfocality is the condition in which the video image remains in focus as the magnification is adjusted from highest to lowest. Starrett zoom optics are designed to maintain parfocality throughout their magnification range. To check parfocality, always reference a flat, sharp edge.
6. Report any observed discrepancy. If the error is verified, contact your Starrett representative for authorized service. 6.3.2 Zoom Optics Parcentricity Parcentricity describes the condition where a feature remains at the optical center of the video image throughout the magnification range. Like parfocality, parcentricity requires that the feature be first located at highest magnification.

Verification Standard Placement Steps to validate calibration: 1. Place the calibrated verification standard in one the six positions on the glass stage as shown above. Secure the standard with hot melt glue or other suitable retaining method so that stage translation cannot move the standard under any condition. 2.
Calibration Error Chart Example Cleaning To the degree possible, the system should be kept in a clean environment, away from dirt, dust, oil and debris which could affect system performance or degrade the system’s mechanical and electronic parts. If a clean environment is not available, the machine should be kept as clean and protected as is possible.
Critical components are covered and are not user serviceable. Should the stage mechanics bind or require service, contact your Starrett representative. The lead screws use a self-lubricating TFE coating, which is designed to last for the life of the product. Do not apply cleaner or lubricant, which could collect dirt and impair system performance.
GLOSSARY The following terms may have additional meanings. The definitions that follow are in the context of the MVR video metrology systems. Accuracy The maximum error that the system will produce when measuring a true standard. All-in-one PC A space saving personal computer where all electronics, disk drives and I/O connections are in the same enclosure as the video monitor, which is an LCD color touch-screen.
Page 26
Resolution The least significant digit to which a physical quantity can be read. High resolution does not imply high accuracy. Skew Misalignment of the part with respect to the X and Y axes. This will create measurement errors unless the part is repositioned or the deskew feature of the metrology software redefines the measurement axes.
