Recover from an interrupted scan
Retain partial input as incomplete, inspect the provisional result and capture a complete replacement.
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.
Recover from an interrupted scan
- Start capture in the focused box
Start capture in the focused box.
Start capture explicitly. Only this box collects keyboard input. These keystrokes are simulated; the course does not measure a physical scanner.
- Enter only part of the value
Enter only part of the value.
This input is unfinished. Moving focus must retain it as an incomplete observation instead of treating it as a successful scan.
- Move focus away from capture
Move focus away from capture.
Focus loss pauses collection and retains the partial text. Do not use an incomplete record as production confirmation.
- Inspect a provisional comparison
Inspect a provisional comparison.
Even when the text happens to agree, an incomplete capture has only a provisional result. Start again before accepting a check.
- Start capture in the focused box
Start capture in the focused box.
Start capture explicitly. Only this box collects keyboard input. These keystrokes are simulated; the course does not measure a physical scanner.
- Capture the complete replacement value
Capture the complete replacement value.
Restarting capture focuses the box. This complete value replaces the partial observation for comparison; the incomplete history remains visible.
- Confirm the recovered exact value
Confirm the recovered exact value.
Check against the complete known value. A successful recovery does not delete the incomplete observation or its reason.
