  • Page 14: Changing Bayonet Mounted Optics

    If the system is to be operated under environmental conditions that are substantially different from those shown above, the system should be recalibrated under the expected conditions. Also consider material characteristics, such as coefficients of thermal expansion of the parts under inspection.

  • Page 15: Safety Considerations

    Disconnect all power sources prior to moving or working on the equipment. Consult Starrett if you have any question regarding transporting, using or maintaining these systems.

  • Page 16: System On/Off Controls

    System On/Off Controls In AV350 and AV450 systems, the front panel of the pedestal has a master power switch for the system and a second power switch for the M3 controller. Use this second switch to reset and initialize the M3 controller when needed. Turning on the master power switch will automatically turn on the computer.

  • Page 22: Electrical Power

    Electrical Power Brick-type power adapters AV300 systems are powered by three “brick” type AC adapters: one for the all-in-one touch- screen PC, one for the M3 controller, and one for the illumination controller. The AC adapters all accept 100/240 Vac power for worldwide use. They are normally plugged in a switchable outlet strip, which is shipped with the system and serves as the master power distribution point.

  • Page 23: Installation

    INSTALLATION Your metrology system was carefully secured in a custom crate for stability and protection during shipment. Exercise care in handling the shipping crate, as excessive force or shock may damage its delicate contents. Required Tools The following items are typically required to uncrate and install the metrology system: Phillips screwdriver Battery powered drill (Phillips bit recommended) Standard slotted screwdriver...

  • Page 24: Lifting Of Av350 / Av450 Metrology Unit

    Removing Shipping Retainers AV systems (and other Starrett metrology systems) use metal lock-down tabs to prevent move- ment of critical motion components during shipment. These are intended to be removed once the equipment has been placed in its final position. Look for the lock-down metal tabs and permanently remove them.

  • Page 28: Cnc And Manual Control Modes

    CNC and Manual Control Modes CNC programmable settings include X-Y stage position, Z-height (for focus adjustment), zoom, and lighting. M3 CNC metrology software is factory configured for AV300 and AV350 systems. Please refer to the separate M3 CNC Software manual.

  • Page 29: Focus Considerations

    5.4.4 Parts Fixturing The part must be fixtured securely to prevent part movement during measurement. Options are available from Starrett Kinemetric for off-the-shelf, semi-custom or custom fixturing. Please contact Starrett Kinemetric sales with your requirements. Aligning the part’s X or Y axis to the stage will improve dimensional measurements. If the part is off-axis from the stage, X-Y-Z measurements will not correlate as well with true part dimensions.

    Therefore, in order to properly inspect parfocality, always reference a flat, sharp edge. Do not select a rough or sloping feature. Starrett’s MAG checker is provided with the system and is an ideal part to use in parfocality inspection.

  • Page 31: Parcentricity

    5. While observing the feature, slowly adjust the magnification lower. Verify that the feature remains focused as the magnification is lowered. 6. Report any observed discrepancy. If the error is verified, contact your Starrett representative for authorized service. 6.2.2 Parcentricity Parcentricity describes the condition wherein a feature will remain at the optical center of the video image throughout the magnification range.

  • Page 32: Calibration Verification

    A calibration verification standard artifact is available from Starrett authorized distributors or directly from the Starrett service department. Calibration should also be verified after the system has been serviced or moved. The following is a brief description of the steps recommended for the verification of your machine.

  • Page 33: Cleaning

    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.

  • Page 34: Cleaning Mechanical Parts

    To ensure a long, trouble-free service life, wipe down the system regularly to remove any dust or dirt from the system. Most critical components are covered and require no user service. Should the stage or column mechanics require service, please contact your Starrett representative. Lubrication Every 6 months, lead-screws may be lubricated with a small amount of Tri-Flow®.

  • Page 35: Bulb Replacement (Fiber-Optic Lighting)

    Bulb Replacement (Fiber-optic Lighting) NOTE: The lights of a fiber-optic metrology system generate heat. To preserve lamp life and reduce unnecessary heat buildup, turn the lights down when the system is not in use. WARNING: Power the system down properly and unplug the unit from the power supply before opening the electronics enclosure.
