# Run and Validate

:::action[Run a normal inspection]

1. In **Quality → Schedule → Active Checks**, add an `Offline Lab Inspection` for asset `QA Station` and open it.
2. On the **Analyzer** tab, click **Get Analyzer Data**, then **Take Measurement**. Particle Size and Particle Density fill in, and Standard Deviation and Coverage are calculated.
3. On the **Calibration** tab, enter the analyzer calibration date.
4. Submit. The check stays in **Submitted** because the sheet requires sign-off. Approve it.

:::

The test fail action didn't fire, and couldn't: nothing on the sheet has a spec yet, so nothing can fail. You'll add one through a revision.

:::action[Add a tolerance to Particle Size]

1. In **Configuration → Quality → Check Sheets**, set `Offline Lab Inspection` to `In Revision` and open it.
2. Open `Particle Size` and set its specification to Tolerance: LEL `0`, LSL `25`, LCL `50`, Target `75`, UCL `100`, USL `125`, UEL `150`.
3. Save, close, and release the sheet.

:::

:::action[Force a failure]

1. Add another `Offline Lab Inspection` for `QA Station`, and capture the analyzer data.
2. Overwrite Particle Size with `10`. It's below the LSL of 25 but above the entry limit of 0, so Kanoa accepts it and marks it as failed.
3. Enter the calibration date, add a comment for the failure, and submit.
4. Watch for the message that a follow-up check was issued. The helper is issued when the failed check is submitted, before anyone approves it.
5. Approve the lab inspection. Then in Active Checks, open the `QA Station Inspection Failure` check, add an image, and submit it.
6. Add one more `Offline Lab Inspection`. The Calibration tab now shows the date you entered last time.

:::note
A persistent value may not carry over to a new check sheet version, so the first check after a revision can start blank. From then on, the value carries forward.
