Tachometer/Fuel Monitor

The tachometer/fuel monitor provides both the functions of a tachometer and a fuel-engine monitoring system. The analog tachometer looks like a standard analog device but is actually a digital instrument. On smaller pointer movements, you may occasionally see the pointer moving in the one-third degree “steps” that represent the accuracy of the instrument.

The tachometer LCD screen displays several user selected functions. The displayed data includes: “engine hours,” “time remaining,” “engine temperature,” “oil pressure,” “system voltage” and engine alarm conditions.

Pressing the “mode M” button will select the various functions as shown in the Tachometer Display Sequence.

In order to minimize “false” alarms, the “low voltage” alarm only functions when the engine is known to be running based on the presence of tachometer data.
