5. Installation and Setup This section provides information on unpacking, installing, and setting up the AVR400 system. SKE metrology systems are normally installed by factory-trained technicians who also provide operator training. The following information covers basic hardware installation if an installer is not available. Refer to “On-Site Installation, Calibration and Training” later in this section for more information on SKE installation and calibration services. 5.1 Planning the Placement of Equipment When planning the placement of the AVR system, refer to the following recommendations: • Ensure a clean operating environment to minimize the accumulation of dirt on the optics and on precision mechanical parts, such as lead screws and encoder scales. • Ensure the planned installation location has the proper electrical requirements. Refer to “Electrical Specifications” earlier in this document for detailed information. • Select an installation location where the temperature can be controlled to within 20°C ± 0.5°C (68°F ± 5°F), which is the calibration temperature of the system. • It is recommended (but not essential) the system be placed on a level work surface using a bubble level for verification. • AVR systems are designed to be installed on a benchtop at a height of approximately 85 centimeters (33.5 inches). The height of the optional workstation can be adjusted to suit the requirements of the operators. • Allow 60 centimeters (24 inches) to right or left side of the metrology unit to position the monitor. • Allow additional clearance of 30 centimeters (12 inches) on both sides is recommended for general access. • Allow a minimum of 5 centimeters (2 inches) behind the unit for air flow, as the electronics compartment only uses convective air cooling. • Allow 50 centimeters (20 inches) of space at the back of the unit to completely open the hinged door for service access. If necessary, the metrology unit can be moved as needed for service. Refer to “System Specifications” earlier in this document for the detailed information on the dimensions of the system. 5.2 Moving the Crated System The AVR400 is shipped in a wooden shipping crate. Use a forklift or pallet cart to move the crate within the building to the final location where the system will be installed. Exercise care in handling the unopened shipping crate, as excessive force or a drop can damage the contents.

A complete functional test and calibration are recommended following physical installation. Professional system installation is normally provided by Starrett Factory Service Technicians or Starrett Authorized Service Technicians for all new vision metrology systems and optical comparators sold in North America. Installation can include equipment setup, on-site calibration and on-site operator training. While professional installation, calibration and training are separately quoted line items, these services are highly recommended and are purchased by most users. As part of its setup services, Starrett may oversee 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 process typically takes half day for an AVR system. The system should temperature stabilize for 24 hours prior to calibration. On-site calibration normally takes place following setup. Starrett offers ISO 17025 accredited calibrations. Calibration uses NIST-traceable glass standards and gage blocks. Calibration typically takes half to one day for an AVR system. If a motorized rotary stage is purchased with the AVR system, then additional installation, set-up and calibration is required which can add another two hours of technician time plus the appropriate calibration equipment. On-site basic operator training can be provided following calibration. This typically takes half day for an AVR system. Many customers choose to augment basic training with additional
