When working with sophisticated testing and measurement equipment like the Fluke MDA-550 Series III Motor Drive Analyzer, Fluke 190 Series III ScopeMeter®, or Fluke 430 Series II, ensuring seamless integration with your computer systems is crucial. However, users may encounter a common hurdle where their Windows 10 or Windows 11 machine fails to recognize the device, even after manually installing the USB driver as per the Fluke-190 Series II guide. This article provides a simple yet effective solution to this issue.

The Solution

The key to resolving this recognition issue is adjusting a specific security setting within Windows known as "Memory Integrity." By disabling this feature, users have reported successful recognition of their Fluke devices by the PC.

Step-by-Step Guide

1. Navigate to Core Isolation Settings: Open the Core isolation page by clicking on "Start" > "Settings" > "Update & Security" > "Windows Security" > "Device Security."
2. Access Core Isolation Details: Under the "Core isolation" section, click "Core isolation details."
3. Disable Memory Integrity: Locate the "Memory Integrity" setting and toggle it off.
4. Restart Your Computer: Windows will prompt you to restart your computer to apply the changes. Proceed with the restart.
5. Update the Driver: After the system restarts, open "Device Manager" and check for the Fluke device. If detected, proceed to update the driver accordingly.

Conclusion

Following the above steps, users can overcome the device recognition and fully utilize their Fluke Test Tools with their Windows 10 or Windows 11 machines. This simple tweak can save time and frustration, ensuring a smoother workflow and reliable performance from your Fluke equipment.
