Understand a copied reference
Copy a comparison deliberately, preserve its manual provenance and keep earlier checks.
For operators
Read these instructions on any device. Watch or practise a chapter on a desktop or laptop, with a desktop or mobile application layout. Demonstrations use sample data and simulated scanners.
Understand a copied reference
- Start a comparison
Start a comparison.
Use a known reference and check each label separately. These practice values are synthetic. An exact match is not a physical contents or optical approval.
- Keep every leading zero
Keep every leading zero.
Enter the complete reference. MatchBench preserves each character exactly, including spaces and leading zeroes.
- Move on to checking labels
Move on to checking labels.
The reference stays fixed until you deliberately change it. Each submitted comparison stays in history.
- Find the missing leading zeroes
Find the missing leading zeroes.
The value 17 differs from 000017. These are exact strings, not interchangeable numbers.
- Review every retained check
Review every retained check.
Review the newest check first, with its original reference and recorded entry source. A correction does not delete the earlier observation.
- Deliberately copy a value as the reference
Deliberately copy a value as the reference.
Copying an earlier comparison creates another reference group. The new reference is recorded as manual, never as a fresh physical scan.
- Check the copied reference
Check the copied reference.
The copied reference is now 17. This match belongs to its new group; the earlier 17 mismatch against 000017 is still retained.
