How to Install Testo 350 Control Unit Driver

1. Check your Windows version and system architecture. Confirm whether your PC uses a 32-bit or 64-bit edition before choosing the Testo 350 Control Unit driver download for Windows.
2. Select the correct package. Look for the latest version that explicitly supports your operating system and device. For Windows 10/11 searches, note that Windows 10 is listed as supported here, but Windows 11 compatibility is not confirmed. Verify compatibility before proceeding.
3. Download and prepare the files. Use a trusted source for any free download, check that the package identifies Testo as the vendor, and extract the files if they arrive in an archive.
4. Install the driver. Follow the included setup instructions, including when to connect the USB cable. If no installer is provided, use Device Manager to locate the device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, connect the control unit using a suitable USB cable, and check Device Manager for warnings. Open compatible Testo software to confirm that it detects the device.

Keep the driver updated when Testo provides a compatible release, particularly if you encounter connection problems or change your Windows installation. Before an update, review the package’s compatibility notes and retain a copy of the working installer so you can restore your previous setup if necessary.
