- ❌ No → Your otoscope is not supported by Measure . Contact Auditdata Support for compatibility advice.
The Orl Vision OX1 is primarily compatible with Windows 7 and Windows 8. On Windows 10 or 11, use the OX2 or Firefly models instead.
Step 2: Verify the otoscopy license
Is the otoscope visible in Measure after connecting it?

- In Measure , go to Help → License Generator.
- Open the License Generator and enter the Measure serial number. The otoscope serial number is not required.
- Apply the generated licence and restart Measure .
→ Check if the otoscope is now visible. If yes - proceed to Step 3. If no - continue to Step 3 for driver installation.
Step 3: Install the required drivers
Are the required drivers for your otoscope already installed?
