# Diagnostics

Compatible with: LRS4000 multiScan100 multiScan200 picoScan100

If you cannot solve a problem with the [Troubleshooting](https://sickag.github.io/sick_lidar_developer_guide/troubleshooting/) tables or the
[Error Codes](https://sickag.github.io/sick_lidar_developer_guide/troubleshooting/error-codes/), create a diagnostic file on the device. The file
collects diagnostic data of the device in one ZIP archive. SICK uses it to
analyze the problem.

## SOPASair Diagnostics

Open the web interface of the device and go to **Diagnostics → Overview**. The
page shows the current device status, the message log, and the
**Diagnostic file** tile.

*SOPASair **Diagnostics → Overview** on a picoScan100: status, messages, and the **Diagnostic file** tile with **Create file** and **Download**.*

## Create and Send a Diagnostic File

1. Reproduce the problem, or create the file soon after it occurs.
2. Log in with the Service [user level](https://sickag.github.io/sick_lidar_developer_guide/shared-features/user-levels/) or
   higher.
3. In the **Diagnostic file** tile, click **Create file**. A new file
   overwrites the previous one, and the previous file can no longer be
   downloaded.
4. Click **Download** and save the ZIP file on your computer.
5. Send the file to SICK through your local SICK contact for analysis. Add a
   short description of the problem, the part number, the serial number, and
   the firmware version. See [Contact](https://sickag.github.io/sick_lidar_developer_guide/contact/) for the contact options.

You can also create the file over the REST API with `DoDiagnosisDump`. See the
REST API | OpenAPI page of your device for the available diagnostic endpoints.

The diagnostic file may contain information about your installation. Do not
post it in public forums.
