EDM-740 Pilots Guide Supplemental Information
This section describes the added capabilities and operation of the EDM-
740 model. The added capabilities are:
Fuel Pressure:
Monitors fuel pressure ranges for either carbureted or
injected engines. Fuel pressure is displayed in the 'Scanner' area and
optionally as a linear gauge via 'Display Customization'. Sensor type and
low and high fuel pressure alarm limits are programmable in the Factory
Limits setup area.
Amps:
Monitors positive or negative amperage flow at the location of
your choice - typically either a bus 'loadmeter' or battery
'charge/discharge' configuration. Amps is displayed in the 'Scanner' area
and optionally as a linear gauge via 'Display Customization'. Low and
high amps limits are programmable in the Factory Limits setup area.
Fuel Level: Addendum f
Fuel level is displayed in the 'Scanner' area and optionally as a linear
gauge via 'Display Customization'. Calibration is performed in the aircraft
and saved inside the instrument. The most popular resistive, voltage or
frequency output level sensors are compatible (not supplied). The
calibration data entry and low fuel level alarm values are programmable
in the Factory Limits setup area. See 'Factory Limit Program Mode
additions' section below. Detailed calibration instructions can be found in
the Installation Instructions or the EDM-740.
HOBBS:
The hobbs function displays total engine running time. This is
visible for several seconds when the instrument is first turned on, after
the engine is stopped or via the Pilot Program Mode.
Clock:
The clock function is displayed in the Scanner area in 24 hour
format (00:00:00 to 23:59:59). This is initially set via the Pilot Program
Mode.
Timer:
The timer function is displayed in the Scanner area and provides
Hours:Minute:Seconds resolution. While displayed, the timer count can
be started and stopped, by tapping the LF button. Holding LF resets the
timer.
For Your Safe Flight
Monitors fuel tank levels (maximum of two).
