EDC-D10 Installation and Calibration 2
4) The EDC Calibration Program downloaded from our web site and loaded on the
laptop.
5) An accurate method of aligning the airplane with North, East, South, and West.
We have used a compass rose at the airport for this.
6) Appropriate cables to connect the laptop to the EFIS.
Once you have the installation completed and verified, a laptop connected to the EFIS-
D10 with the EDC Calibration program, and a place to perform the calibration, perform
the following steps:
1) Turn on the EFIS-D10 and allow it to warm up for at least 15 minutes before
performing the calibration.
2) Start the EDC Calibration Program on the laptop and verify data is being
displayed in the window of the program. If no data is being displayed, check if
the data is available on one of the other available COMM ports using the pull
down window in the EDC Calibration Program window. If no data is available on
any of the COMM ports, check your cabling to make sure it is correct.
3) Align the airplane pointing North as closely as possible.
4) On the EFIS-D10, navigate the menus to SETUP->MAGCAL. When you press
the MAGCAL button, you should see the data length change in the window and
the message “Collecting data for NORTH” will appear. A counter will indicate
the data is being stored and after about 15 seconds, a second message “Finished
taking data this position” will appear.
5) Align the airplane pointing East as closely as possible.
6) On the EFIS-D10 press the left most button labeled GNDNRT. The EDC
Calibration Program window will display “Collecting data for EAST.” After
about 15 seconds, the message “Finished taking data this position” will appear.
7) Align the airplane pointing South as closely as possible.
8) On the EFIS-D10 press the 2
nd from the left button labeled AIRRGT. The EDC
Calibration Program window will display “Collecting data for SOUTH.” After
about 15 seconds, the message “Finished taking data this position” will appear.
9) Align the airplane pointing West as closely as possible.
10) On the EFIS-D10 press the 3
rd from the left button labeled AIRLFT. The EDC
Calibration Program window will display “Collecting data for WEST.” After
about 15 seconds, the message “Finished taking data this position” will appear.
11) Press the EFIS-D10 button labeled END. This will cause the EDC Calibration
Program on the laptop to calculate the calibration constants and upload them into
the EFIS-D10. The program will also display the average error. This value can
be rounded to the nearest integer and used to adjust the magnetic heading in the
EFIS. To do this, navigate the EFIS-D10 menu structure to SETUP->MAGADJ.
Use the up/down arrows to enter in the suggested magnetic adjustment value.
