- Use a spatula or smear slide to clean the cut surface of the core by lightly scraping away any material that was smeared across the surface during core splitting.
- Bring the endcap of the section half (usually A for archive half) to be measured to the SHMSL. Use the endcap rather than the label on the bottom of the section to scan the barcode for sample information, to prevent accidentally dropping the section half.
- Place the archive section in the core tray with the blue endcap up against the benchmark. The benchmark is the white square at the head of the rails that hold the section halves (Figure 27).
Figure 27. Benchmark - Adjust the section so that it is as flat as possible with respect to the plane of the benchmark. There is a limit to how much the sensor heads can float when they land on a tilted section.
- Do not wrap the cores yet. The Acuity AR700 laser cannot reliably see through the plastic to measure an accurate profile of the section half surface.
