It belongs with the test & measurement and wearables designs in this gallery.
From the project
USB IR Adapter compatible with Fluke 287 and 289 series multimeters
Recommended description: USB IR Adapter compatible with selected Fluke multimeters
This project uses a simple function-based product numbering style. FIC identifies the Fluke-compatible infrared cable family, and 100A identifies this product generation.
This project is an independent, third-party design compatible with selected Fluke instruments. It is not made by, endorsed by, sponsored by, or affiliated with Fluke Corporation. Fluke is a trademark of Fluke Corporation.
