A22 · Reference edition 2026.11
Probe access — Layout and sequence
A nominally clear measured feature may be inaccessible along the probe approach or withdrawal path. Include the whole inspection movement.
Scope and purpose
Place the relevant elements in a visible order before completing the record. A diagram should distinguish position from sequence and should preserve the orientation used in the written notes. Review the example for a practical way to make the relationship explicit.
Working notes
This reference collection concerns light, offline dimensional-inspection layouts. It brings locating concepts, component descriptions and revision records together without substituting for an engineered fixture design. The drawings are original explanatory diagrams. Reference IDs identify documents, not commercially tested products. Read the scope and limitations alongside each example, and keep the actual part drawing and inspection requirements available when reviewing a proposed layout.
Practical example
Draw the approach envelope as a separate translucent region around the target feature.

| Limits and interpretation | A static sketch does not prove collision-free operation on a particular machine. |
Review checklist
Identify the starting condition; mark the order or orientation; check that labels in the figure match the accompanying table.
