One of the most common ways to check caliper or micrometer calibration is with gage blocks. These tools are increasingly important for verifying physical dimensions. Gage blocks must be in good condition to provide accurate measurements and to prevent damage to other instruments. Regular gage block maintenance will extend usable life. By keeping blocks clean and free of debris, micrometers or calipers will have greater protection against deterioration.
