7.1 Daily Inspections
On a daily basis, 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.
7.2 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, call for service. The lead screw uses a self-lubricating TFE coating, which is designed to last for the life of the product. Do not apply cleaner or lubricant. • Do a basic calibration check against a certified chrome-on-glass standard, such as Accurite 25mm fiducial. Do 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 HVR’s specifications.
7.3 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. In harsh environments, preventive maintenance and factory service should be scheduled more frequently to keep the system in top working order.
WARNING: Never pour fluid on the system when cleaning. Do not over- wet cleaning cloth. Excessive moisture can seep into mechanical or electrical parts, damage the equipment and possibly cause an electrical short circuit and physical injury. As a precaution, unplug the system before cleaning. Always unplug the system before using any flammable cleaning fluid.
7.3.1 Cleaning External Surfaces
Wipe down the system with a clean, lint-free cloth moistened (not wet) with plain water or Simple Green ® . Never wipe down with acetone or other harsh solvents, which might damage painted or plastic surfaces. Isopropyl alcohol may be used to clean surface contaminants where Simple Green proves ineffective.
