Safety of Machinery, Principles for Risk Assessment Disclaimer of Liabilities The L.S. Starrett Company shall have no liability or responsibility to the customer or any other person or entity with respect to any liability, loss or damage caused or alleged to be caused directly or indirectly by this documentation, or the hardware and software described in it.
HDV PRODUCT LINE DESCRIPTION The HDV300 with 300 mm (or 12”) of travel and HDV400 with 400 mm (or 16”) of travel are hori- zontal digital video comparators which combine the best features of a vision metrology system and a horizontal optical comparator. They come with a 5-megapixel digital video camera and are available with a choice of seven telecentric lenses that provide micron-level resolution and optical distortion as low as 0.001% across the field of view (depending on the lens) for accurate field-of-...

counterclockwise to release the stage, then clockwise to lock down the stage once you have set the desired skew angle. Focus adjustment over 2” (50 mm) is achieved by moving the stage horizontally toward or away from the camera optics. This adjustment uses a hand wheel with a hand crank at the front of the stage, as shown in Figure 2.
Figure 3. System component overview, CNC system Manual Position and Illumination Controls in CNC System The CNC version of the HDV300 and HDV400 allows fully automatic operation under program control for illumination, for right-left position of the stage (X-axis), for up-down position of the stage (Y-axis), and for in-out position of the stage (Z-axis, used for focus adjustment).
Page 10
Position control of the stage in the X, Y and Z axes can be via the joystick and trackball unit as illustrated below. X-position control can also be via a knob at the end of the X drive shaft. First press the red emergency stop switch at the back of the joystick and trackball unit, which removes power from all servo-motors.
Keyboard Adjustment The system keyboard is secured magnetically to a tray, which is held by a ball joint at the end of a pivoting swing-out arm, as shown in Figure 5. Adjustment of the ball joint and pivot angle sets the keyboard angle and position.
Store unused lens assemblies in a safe place, since they are breakable and expensive. Lighting Control HDV300 and HDV400 system provide long-life LED lighting for surface and profile illumination. Lighting levels are adjusted via the system’s M3 software by sliding graphical controls on the touch-screen.

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. Users should also consider the material characteristics of the parts under inspection, in particular coefficients of thermal expansion.
3.10 Safety Considerations General Starrett vision metrology systems are designed for safety and proper ergonomics Safety during normal use. Exercise caution when lifting, handling or moving the system to maintain equipment calibration and measurement performance. Consult Starrett if you have any question regarding transporting, using, or maintaining this system.
3.11 Equipment On/Off Control HDV300 and HDV400 systems have an On/Off rotary selector switch on the right side of the housing, and a rocker switch in the back just above the 115/230V power connector (as required by for CE certifica- tion).
Figure 9. Dimensioned outline drawing, manual system Required Tools and Equipment The following items are required to uncrate and install HDV300 or HDV400 metrology systems: 1. Forklift or pallet cart (to move shipping crate inside building), 2. Battery powered drill with Phillips bit (to remove top and sides of shipping crate), 3.
Remove all wood screws from the side panels of the crate, then remove the panels. This will expose the HDV300 and cabinet stand (if ordered) on the pallet base of the crate. 2. Lift the cabinet stand (if ordered) off the pallet base.
(in the back and on the side). Starrett vision metrology systems and optical comparators are factory set for 115V or 230V AC power, depending on the destination country. Contact Starrett if you ever need to move a system to a country with different AC power.

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.
2.47” x 1.86” (63 x 47 mm). If the entire part cannot fit into the FOV, no problem. Simply move the stage by up to 12" (300 mm) with the HDV300 or up to 16” (400 mm) with the HDV400, and the M3 software will seamlessly integrate FOV measurements with encoder readings from stage motion.
the column at the front of the instrument and is collimated so that the emitted rays are parallel to the optical axis of the imaging lens. If glare develops on edges of convoluted, reflective parts, install a furnished aperture into the back light. This aperture limits the diameter of the illuminating lens.
SYSTEM MAINTENANCE HDV300 and HDV400 benchtop horizontal digital video comparators have been designed for years of superior service. Periodic maintenance outlined in this section should be performed to maintain the system in peak operating condition. Perform a daily inspection to ensure that the system is operating correctly and that proper safety guidelines are being followed.
Figure 15. Inline Clean Air Kit Interior With the Inline Clean Air Kit, the fan on the side of the HDV300/400 is replaced with a panel and fittings to allow the use of pressurized air to keep the internals of the machine clean. Pressure between 8 and 15 psi has been found to be effective at sufficiently pressurizing the housing to prevent the ingress of dust, particulates, oil vapors, and similar such as found in machine shop environments.
Zoom Optics Parfocality & Focus Parfocality is the condition in which the video image will remain 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. Do not select a rough or sloping feature.
Calibration should also be verified after the system has been serviced or moved. A chrome-on-glass calibration verification standard artifact, P/N 300LSTD, is available from Starrett or its authorized distributors. This standard has a length of 300 mm and major calibration fiducials spaced every 30 mm.
3. Using the HDV system, measure the position of fiducials spaced every 30 mm. For each fiducial, take the average of multiple readings for improved accuracy. 4. Calculate the absolute measurement error for each fiducial by subtracting the calibrated position of the fiducial from the above average readings, then 5.
Use a clean soft cloth or paper towel to wipe up any excess. NOTE: Use only approved lubricants, as inappropriate lubricants can damage system components. Approved lubricants may be obtained by contacting Starrett or an authorized Starrett representative.
Axis A direction which allows movement and along which dimensions can be measured. In the HDV300, the X-axis is horizontal from left to right, and the Y axis is vertical from bottom to top. Blooming A condition where the parts of the video image are distorted by oversa- turated bright regions, making objects appear larger than they really are.
Page 29
Repeatability The three-sigma variation of multiple readings on the same object that is positioned at multiple locations across the field of view. Resolution The least significant digit to which a physical quantity can be read. High resolution does not imply high accuracy. Squareness The alignment of the camera relative to the motion of the metrology stage.
