NIST explains metrological traceability and its supporting measurement context. A manufacturer can propose an original task that matches a requested observation to the correct instrument, range and calibration record. NIST traceability guidance
Prepare fictional instrument cards, range identifiers and calibration tables. Give two channels similar numeric readings but different configured ranges. Ask which observation answers a stated request. Include a later range change and a report missing the channel identifier. The key should retain the effective range and identify the unsupported association.
Annotate instrument, channel, range, property, unit, date and report version. Evaluate with a new table format and an explicitly supplied calculation rule. Score wrong-range selection, a later configuration applied to earlier data and guessed channel identity independently. A complete example should contain enough evidence for a reproducible answer with its source fields cited.
Use self-authored records and invented values without operating a process. Customer production information, licensed methods, proprietary configurations and outside calibration material need permission and qualified review. A licensing brief should state the range-selection task and checked key. Establish buyer requirements before preparing commercial histories or new capture.

Original Fiund exercise
A midpoint check is not coverage of a whole range
Mock instrument report stubs use named points and no real calibration procedure.
| Record | Source | What it records |
|---|---|---|
| 1 | Request | Coverage at low, midpoint and high on toy range R2. |
| 2 | Report A | Range R2 midpoint recorded; low and high absent. |
| 3 | Report B | Range R1 low and high recorded. |
Question for the model
Which requested R2 points are supported?
Show the reference answer and checks
Only the R2 midpoint is documented in record 2. The endpoints in record 3 belong to R1 and do not transfer across ranges. A reviewer should record one covered point out of the three requested, without asserting full-range calibration.
- Treating midpoint coverage as full-range coverage
- Merging endpoint evidence from a different range
Fields to preserve
- range_id
- Identifies the test domain
- point_position
- Tracks coverage within it
- point_evidence_status
- Keeps missing endpoints explicit
Test another case
Use a shared physical point appearing under two ranges; require scope evidence even when values coincide.
No real calibration procedure, instrument setpoints, compliance claims or plant data.

Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
