Maintaining the System
8.
AVR vision metrology systems have been designed for years of superior service. Periodic maintenance as outlined in this section is considered good practice to maintain your system in peak operating condition.
8.1 Performing Daily Inspections
Each day, inspect your system for general safety and basic functionality:
• Verify that the work area is clean, dry, and free of debris. Remove any debris or loose items from around the system and metrology stage.
• Verify that the electrical power cords are plugged into a grounded power source and are unobstructed.
• Verify that temperature and humidity are within recommended ranges. Refer to “Environmental Conditions” earlier in this document.
8.2 Weekly Inspections
On a weekly basis, or if the system has been moved, do the following:
• Verify that the stage control mechanisms move freely. If binding is observed, contact SKE Technical Services for service. 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. • Perform a basic calibration check against a certified chrome-on-glass standard, such as Starrett’s MAG Checker, part number 8268. (Refer to “Spare Parts and Accessories” later in this section.) With a telecentric system, perform a single measurement on an artifact whose dimensions are comparable to those of the parts to be measured, and verify that the measured dimensions are within the AVR’s specifications. With a zoom system, measure artifacts at the zoom detent positions for maximum and minimum magnification.
8.3 Monthly Zoom Optics Alignment Verification
The system’s zoom optics (if part of the system) should be verified monthly for parfocality, parcentricity, and squareness to ensure accurate measurement. Verification is straightforward and can be performed as often as desired.
Caution
While optical alignment verification may be performed by an operator, optical alignment correction should only be performed by an authorized service technician. If alignment discrepancies are found, contact Starrett or your local Starrett representative to schedule authorized service.
