General Safety
MVR systems are designed for safety and proper ergonomics during normal use. Exercise caution when handling or moving the systems to maintain calibration and measurement performance. Disconnect all power sources prior to moving or working on the equipment. Consult SKE if you have any question regarding transporting, using, or maintaining the systems.
Electrical Safety
MVR systems do not contain hazardous AC line voltages, as these are contained on the input side of the system’s AC adapters, which are UL listed. Even at these low voltages, there is the potential of electrical component damage caused by accidental short circuits. For maximum electrical safety and minimal risk to the equipment, adhere to the following guidelines: • Ensure that the power receptacles for the AC adapters are properly grounded 3-prong polarized 100-240VAC for use in North America or appropriate safety-rated receptacles for use outside of North America.
• Do not operate the systems with housings open except for service by a factory trained technician.
• Keep liquids away from the systems, and do not operate the equipment in excessively humid conditions, as water can cause short circuits.
• Keep metal filings away from the systems, as such debris can cause short circuits.
• Do not operate the equipment around volatile or flammable solvents, as local electrical heating could cause ignition.
• Disconnect power, or do not plug in the power cord, if hazardous conditions exist such as a damaged or frayed power cord, a damaged or improperly grounded power receptacle, equipment exposure to liquid spills or excessive moisture, or impact damage. Have the system inspected by authorized personnel before operating.
There are no fuses or user-serviceable items in the systems. Systems should only be opened by a factory-trained service technician.
Mechanical Safety
• MVR systems are heavy. To avoid possible back injury, use multiple people to lift. Bend your knees, not your back.
• Only manually lift MVR systems by the two red carrying handles and shipping lift bar. For more information on lifting the system, refer to “Removing Shipping Retainers” later in this guide.

5.6 On-site Functional Test, Calibration and Training
All Starrett vision metrology systems and optical comparators are calibrated at the factory prior to shipment; however, it is possible that components may have moved during shipment. A complete functional test and calibration are recommended following physical installation. Professional system installation is normally provided by Starrett for all new vision metrology systems and optical comparators sold in North America. Installation includes equipment setup, on-site calibration, and on-site operator training. While professional installation is a separately-quoted line item, it is highly recommended and is purchased by most users. As part of its setup services, Starrett oversees the equipment’s in -plant transportation to its permanent location and uncrating. Starrett then performs the physical setup and electrical connection, followed by a completed functional checkout. This typically takes half day for a manual system. The system is then allowed to temperature stabilize overnight. On-site calibration normally takes place on the day following setup. Starrett offers ISO 17025 accredited calibrations. Calibration uses NIST-traceable glass grids and gage blocks. Calibration typically takes a half day for an MVR manual system. On-site basic operator training is provided following calibration. This typically takes half day for an MVR manual system. Many customers choose to augment basic training with additional hands-on training, where new operators program actual parts of the type on which they will be working. Training is with the new equipment and is limited to one to three 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. Installation services in North America (USA, Canada and Mexico) are provided by professional installers and service technicians operating out of the Laguna Hills, CA, headquarters of Starrett Kinemetric and its regional sales offices. Outside of North America, installation services are provided by Starrett subsidiaries in Brazil (for South America), Scotland (for Europe and Africa), China (for Mainland China), and Singapore (for Southeast Asia and Australia).

6.3 Verifying Basic M3 Software Operations The following information provides basic instructions for operating the M3 software. For detailed information, refer to the MetLogix M3 Video and FOV Inspection Software User’s Guide included with your system.
To start the M3 software, perform the following steps:
1. Double-click the M3 software icon on the desktop. Refer to the following figure.
This action displays the interface below.
2. Select Start or touch the Start button on the screen. You will need to move the hand cranks until the screen tells you that that axis is homed.
3. Once the machine is homed, the screen indicates the machine is homed and there is a green checkmark in the upper right corner of the screen. Touch or click on the screen.
For accurate measurement, this checkmark must be green before proceeding.
6.4 Changing Optics Assemblies
MVR systems are equipped with a bayonet optics mount that allows optic assemblies to be changed quickly by the user, for example to switch from zoom operation to fixed-magnification telecentric measurements, or to switch between telecentric lenses with different magnifications. Note : The positioning of different optics assemblies in the bayonet mount is not exact, so do not change optics in the middle of a measurement run. An LED quad ring light is normally part of the 6.5:1 zoom optics assembly and should always remain attached to that assembly. A different LED ring lights fits all telecentric lens assem- blies from 0.3X to 4.0X. This ring light can be transferred from one telecentric lens to another when these have been removed from the system. Refer to the following figure.
Figure 20. 6.5:1 Zoom Optics assembly (left), Telecentric Optics Assembly (right)
Before You Begin
Before you begin removing the optics assembly, review the following information to prevent damage to the optics:
• Use two hands to remove a lens assembly, as it is heavy and is suddenly released. A drop onto the stage glass could break the lens and the stage, causing damage.
• Do not leave the camera unprotected by a lens assembly to minimize dust settling on the CCD sensor surface.
• Do not touch optical surfaces. Oil from your hands can permanently damage optical coatings.
• Place unused lens assemblies in a polyethylene Ziploc bag for dirt protection.
• Store unused lens assemblies in a safe place, since they are breakable and expensive.
Procedure
To remove a lens assembly from the system, perform the following steps and refer to the following figure:
1. Detach the electrical connections from the ring light by doing the following:
a. Pry the plastic latch open with a flat-blade screwdriver.
b. Separate the two connector halves.
Figure 21. Unplugging the Ring Light Connector
2. Using two hands, turn the optical assembly a quarter-turn counterclockwise. The assembly will “quick” release.
3. Reverse the process to reinstall the optics assembly.
Figure 22. Removing the Optics Assembly
6.5 Optimizing Substage Illumination
Background
MVR systems with dedicated optics (zoom or telecentric) and without a quick-change bayonet lens mount are shipped with LED substage illumination that is optimized for these optics. No action is required by the user. MVR systems with the quick-change bayonet lens mount require that substage illumination be modified when switching between telecentric and zoom optics, since a smaller aperture will produce better results with zoom optics. This is achieved by reducing the aperture of a
variable aperture if such an aperture is part of the system, or by dropping in an aperture plate if furnished with zoom optics.
Procedure
Access to the substage lighting requires that the glass plate be removed from the MVR stage. To remove the glass plate, perform the following steps:
1. Remove the four screws that secure the glass plate to the stage.
2. Once the screws have been removed, place two fingers in the spaces vacated by the screws and pry up one side of the glass plate. Alternatively, use a suction cup to pull up one side of the glass plate.
6.6 Mechanically Leveling the Stage Glass
Background
The glass plate can be considered level if the video image of an artifact remains in focus at high optical magnification for any stage position. MVR systems allow the glass plate to be leveled mechanically by about 1.5 mm using four screws whose head has been machined to a conical tip. Note that glass does not rest directly on the conical tips but is held by a steel frame. The glass plate is secured by screws with a spring washer.
Procedure
To mechanically level the stage glass, refer to the following figure and perform the following steps:
1. Using a 2.5 mm Allen wrench, adjust the screws as follows:
• Turn a screw clockwise to move it toward the glass plate and raise the stage.
• Turn a screw counterclockwise to move it away from the glass plate to lower it.
2. Orient the washers as shown in the following figure, keeping them barely compressed so that they have an adjustment range.
3. Four-point support will provide pivot action around two diagonal axes, make screw adjustments until the image remains in focus and the glass plate no longer tips around a diagonal axis.
