Laser Label Coverage
Compare required laser labels with labels documented at the installation.
Description
Laser-label coverage compares a supplied installation label inventory with a supplied requirement list.
Laser-label coverage compares a supplied installation label inventory with a supplied requirement list. Coverage concerns names rather than label content or placement.1
Compare required laser labels with labels documented at the installation.
When to use Laser Label Coverage
Use this tool to compare required laser labels with labels documented at the installation.
Prepare the optical measurements, geometry, fitted coefficients or caller-selected thresholds requested. Confirm wavelength, radius/diameter, pulse-width, angle and unit conventions before running the calculation.
How to use Laser Label Coverage and understand its results
- Prepare the optical measurements, geometry, fitted coefficients or caller-selected thresholds requested. Confirm wavelength, radius/diameter, pulse-width, angle and unit conventions before running the calculation.
- Enter requiredLabels, documentedLabels using the field table and calculation rules, then run the tool.
- Read coveragePercent, matched, missing, unexpected. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| requiredLabels | Required labels | list of string | Required |
| documentedLabels | Documented labels | list of string | Required |
Enter a nonempty required list and a documented list, which may be empty. Trim each label, reject blank entries and match case-insensitively in en-US. Deduplicate by normalized key: retain first key position but last trimmed spelling. Return matched and missing required spellings in required order, unexpected documented spellings in documented order, and percentage of unique requirements matched.
coverage%=100 matchedUnique/requiredUnique Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| coveragePercent | Coverage (%) | number; minimum: 0; maximum: 100 |
| matched | Matched items | list of string |
| missing | Missing items | list of string |
| unexpected | Unexpected items | list of string |

}Limitations and assumptions
No label text, wavelength, class, placement, visibility or regulatory compliance is verified.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
