Abstract
An intrinsically-safe handheld field maintenance tool includes a controller, a process communication module, and a display. The process communication module is configured to communicate with a field device using a process communication protocol. The display is coupled to the controller. A user interface module is also coupled to the controller and is configured to receive user input. The controller is configured to detect a user input help request and provide a video output on the display in response to the user input help request.
