Before you leave the ground, a check of the engine instruments is in order.  Press the knob while viewing the main screen to display the engine gauges window.

Up to 16 different sensors can be installed with EFIS/One, or up to 32 with an optional sensor board.  Each sensor can be named how you want it, and the min, max, and redline values can be set.

The engine instrument window will automatically appear on the screen if any sensor reaches the redline value, or if the sensor stops receiving any valid information.  The instruments page will also appear if the change rate exceeds a pre-defined value.  This can be helpful to prevent shock cooling of a cylinder head, or pilot shock if fuel is pouring out of an open fuel cap!
