Oil Pressure: (150/80)
Default is 150. Sets the oil pressure sensor range that has been
wired to the DU.
**CAUTION:
Using an 80 psi sensor while this setting is configured to 150 will cause the
EFIS to display an oil pressure reading that is twice the amount of the actual oil pressure.
5-16: Required Settings Before Flying!
In addition to the ability to interface with a large variety of third-party equipment, the Sport
EX allows the user to customize many aspects of the EFIS. Some of these settings are
to support pilot preferences, such as what data they wish displayed in the data boxes on
the PFD. Other settings are provided to support redundant inputs, labels used to identify
navigation inputs, etc.
Before flying, we recommend setting at least the following items.
•
All settings described in this section above.
