I was contracted by IRDI System to write this 37-page user manual for their Diagnostic Nozzle Receiver (DNR)—a handheld device used to test infrared (IR) signals received from a hydrogen vehicle’s fueling nozzle.
The manual provides end users with clear, structured instructions for setup, operation, and diagnosis of J2799-compliant communications with hydrogen vehicle fueling ports.
Written in Microsoft Word, with images and diagrams created in Photoshop and Inkscape.
