# Run a Dynamic Test

The Dynamic Test involves running the target box through the vision tunnel multiple times, allowing the readers to take images and validate the proper functioning of the vision tunnel. The test consists of six steps, which are mostly automated and require minimal user input.

If you have to abort the test at any time, you can click on the Cancel button at the bottom of the page in each step.

## Prerequisites

Before you start, ensure that the following prerequisites are met:

- Learn about the test and its various steps by reading Steps of the Dynamic Test

- Prepare the Target Box for the Test

- Add weight to the box to ensure it stays on the conveyor belt. Always give the box enough distance before the vision tunnel, so it moves through at full speed.

## Procedure

To run the dynamic test:

1. Open the Apps menu and select the Dynamic Test page of the Tunnel Setup app. You are now at the Welcome step.

   1. Wait until the app finishes preparing your readers.

   2. To continue to theTrigger Check step, click Start.

2. Option: In the Trigger Check step, validate that the readers are triggered correctly.

   1. To validate the trigger settings, run the box through the vision tunnel, and validate that the trigger turns on and off at the correct time.

   2. If the check fails, follow the instructions on the right side of the user interface to fix common problems with the photoeye.

   3. To continue to the Encoder Check step, click Next Step.

3. In the Encoder Check step, first set the Nominal Belt Speed to the actual speed of your conveyor belt.

   1. Place the box on the conveyor belt.

   2. Bring your conveyor belt up to full production speed and run the box through the vision tunnel.

   3. If any of the readers fail the check:

      1. Review and note the messages in the status message column.

      2. If errors are returned on subsequent runs, click Cancel Test, which restores the readers to the original settings.

      3. Fix the encoder errors, for example using DataMan Setup Tool then restart the Dynamic Test.

   4. If every reader passes the test, click Next Step to continue to the Left-Justified Test step.

4. In the Left-Justified Test step:

   1. Place the box on the left side of the conveyor belt with the front side of the box facing downstream.

   2. Run the box through the vision tunnel. If possible, run the box at both slower (less than or equal to 300 ft/min or 1.52 m/s) and faster belt speed (greater than 300 ft/min or 1.52 m/s).

   3. As the box runs through the vision tunnel, the test results appear in the user interface.

      - If any Xs appear, it indicates that a test failed.

        - To review the no-read image, click on the row that has an X. Reviewing the image can tell you why the reader could not read the barcode.

        - You might have to run the box multiple times through the vision tunnel to pass.

      - If all of the rows have green check marks, it means that the readers can read the barcodes correctly.

   4. To continue to the Right-Justified Test step, click Next Step.

5. In the Right-Justified Test step:

   1. Place the box on the right side of the conveyor belt with the front side of the box facing downstream. Otherwise, this step has the same workflow as the previous step.

   2. Run the box through the vision tunnel the same as in the previous step, then review the results.

   3. If all of the rows have green check marks, click Next Step and the Complete Dynamic Test pop-up appears.

6. To complete the test and continue to the next step, click Confirm.

## After the Procedure

- The Restore & Report step automatically restores your readers to their original settings.

- Option: Generate and download a report of the test results. For more information, see Generate Dynamic Test Report.
