Change stock, create a separate check and retain both document identities in the report.

## Keep different test sheets separate

1. **Go back to Prepare the test**

   Go back to Prepare the test.

   Change opens the first step again. The prepared check keeps its sheet; a different selection becomes a new check only when you prepare it.

2. **Change the selected stock after preparation**

   Change the selected stock after preparation.

   The prepared check still belongs to its original sheet. Changing this selection does not turn it into a check of different stock.

3. **Prepare the known test sheet**

   Prepare the known test sheet.

   The original PDF is checked and its preview is rendered from the same bytes. Downloading a sheet does not mean a label has printed.

4. **Record that the label printed**

   Record that the label printed.

   For practice, record that our example label is available. In a real check, choose this only after you have the paper label.

5. **Confirm the sheet name printed on the label**

   Confirm the sheet name printed on the label.

   Check the sheet name and version printed on the label. All the test sheets carry the same barcode values, so a matching scan cannot identify the sheet.

6. **Go on to measure, scan and report**

   Go on to measure, scan and report.

   Once what came out is recorded, the last step opens. A printed label is measured and scanned there; without one, the report still records what happened.

7. **Review both retained checks**

   Review both retained checks.

   The report retains both test-sheet identities. Compare checks without losing which sheet each observation belongs to.

8. **Download the reviewed JSON report**

   Download the reviewed JSON report.

   The real exporter offers the reviewed report for download. Keep it with your setup evidence; the browser does not confirm where you saved it.
