This will display the OAT adjustment menu. Now, press INC or DEC to increase or
decrease the currently displayed OAT value.
It is important to make this adjustment when the air surrounding the OAT probe is at a
known temperature. This can be achieved with a standard thermometer or another OAT
sensor on your plane. Adjust the displayed OAT until it agrees with your independent
temperature reference.
Troubleshooting
OAT value fluctuates wildly
If the OAT probe is improperly wired, the EFIS-D10 will not receive a valid signal from
it. Verify that the three wires coming from the OAT probe are wired exactly as described
in the Wiring Instructions section above.
OAT value is consistently high/low
You need to adjust the displayed OAT value to correct for sensor inaccuracies. Follow
the instructions in the Calibration and Adjustment section above.
INFO items will not allow display of OAT/TAS/DA
The menu system prevents access to the outside air temperature-based information when
either the EDC-D10 is not properly connected to the EFIS-D10 or the OAT probe is not
properly connected to the EDC-D10. First, make sure that the EDC-D10 can
communicate with the EFIS-D10 by moving a headphone speaker around near the EFIS-
D10. If the EDC-D10 is properly connected the heading should not change. If this is the
case, the problem is with the connection of the OAT probe to the EDC-D10. Verify that
the wiring matches that described in the wiring section above.
