CALIBRATION AND ADJUSTMENT<br />
Before adjustment, it is possible for the OAT sensor to read as much as 5 degrees Celsius off the<br />
actual value. Therefore, it may be necessary to adjust the displayed air temperature value to<br />
compensate for this. To make this adjustment, you must enter the menu system and press the<br />
following sequence of buttons: MORE > SETUP > MORE > OAT. This will display the OAT<br />
adjustment menu. Press INC or DEC to increase or decrease the currently displayed OAT value.<br />
It is important to make this adjustment when the air surrounding the OAT probe is at a known<br />
temperature. This can be achieved with a standard thermometer. Adjust the displayed OAT until<br />
it agrees with your independent temperature reference.<br />
TROUBLESHOOTING<br />
OAT value fluctuates wildly<br />
If the OAT probe is improperly wired, the <strong>EFIS</strong>-<strong>D100</strong> will not receive a valid signal from it.<br />
Verify that the three wires coming from the OAT probe are wired exactly as described in the<br />
Wiring Instructions section above.<br />
OAT value is consistently high/low<br />
You need to adjust the displayed OAT value to correct for sensor inaccuracies. Follow the<br />
instructions in the Calibration and Adjustment section above.<br />
OAT display area states OAT NOT FOUND<br />
Ensure that you have selected the number corresponding to your OAT in the OAT INSTALLED<br />
menu as described above. It can sometimes take as long as 5 seconds for the <strong>EFIS</strong>-<strong>D100</strong> to lock<br />
onto the OAT reading. Ensure that all wiring is correct and that there are no shorted or open<br />
connections.<br />
Other strange behavior by OAT reading<br />
It is possible that your <strong>EFIS</strong>-<strong>D100</strong> and EDC-D10A have mismatched versions of firmware on<br />
them. This most commonly happens when one takes the <strong>EFIS</strong>-<strong>D100</strong> out of the aircraft to connect<br />
to a computer for firmware upgrade. Ensure that the <strong>EFIS</strong>-<strong>D100</strong> and EDC-D10A are connected<br />
to each other and communicating before attempting a firmware upgrade.<br />
