# Offline Lab Inspection

Samples from the finishing line go to a lab analyzer at the QA Station. The technician captures the analyzer's readings, Kanoa calculates derived values, the technician records the analyzer's calibration date, and a supervisor signs the check off. If the sample fails, Kanoa issues a second check that asks for a photo of the failed sample.

That takes two check sheets:

| Check sheet | Role |
|---|---|
| `QA Station Inspection Failure` | Helper sheet: captures an inspection image when the main check fails |
| `Offline Lab Inspection` | Main sheet: analyzer data, calculations, calibration and sign-off |

The helper is built first, because the main sheet has to point to it.

In this section you will:

- Create the QA Station asset, its analyzer tags, and the helper check sheet.
- Build the main sheet with trigger, calculated and persistent items, groups and sign-off.
- Run it, revise it to add a tolerance, and watch a failure issue the follow-up check.
