CALIBRATION
The EFIS-D10 is calibrated at the factory. However, you must perform some simple calibration
routines before your EFIS-D10 can be accurately used.
This section will take you through a series of steps to make sure that you have properly installed
and configured your EFIS-D10. As in the User’s Guide, the term, “button #1” refers to the
leftmost button on the front panel of the EFIS-D10, “button #2,” the next button to the right, and
so on.
Ensuring Proper Installation
Turn your unit on by pressing button #1. Ensure that the screen is bright and readable and that all
instrument displays appear. If a display item is not present, refer to the User’s Guide to use the
CLUTTR feature to display the missing item.
Pitch (In flight)
CAUTION: It is your responsibility to fly your plane safely while performing any configuration
or calibration in flight. The best scenario would include a second person to perform any
necessary steps on the unit.
Once you are flying straight and level, press any button to bring up Main Menu 1. Press MORE
to display Main Menu 2. Press SETUP and then PITCH. Press INC OR DEC until the horizon
line crosses through the center of the crosshairs. It is important that this be done while flying
straight and level to ensure proper pitch and roll display throughout all maneuvers. This pitch
offset may be used to zero the pitch display for panel tilt or whenever center of gravity or other
effects require.
PC Connection Required
The following sets of calibrations and configurations require a PC to be connected to the RS232
communication cable. You must also have the latest EFIS-D10 Support Program downloaded to
your PC. This program may be downloaded from
www.DynonAvionics.com . The magnetic
calibration is the only procedure that requires you have the PC in the plane during flight. The
rest of the following procedures can be performed on the ground or in your home, provided you
have a cable and power supply at home allowing communications with the unit. Be aware that
anytime the EFIS-D10 Support Program connects to the EFIS-D10 the current time setting is
lost. Therefore, do not set the time on the EFIS-D10 until after all calibration and configuration
processes are complete.
Internal Magnetic Field/Heading Calibration (on ground and in flight)
NOTE: if you own the EDC-D10 Remote Compass Module, you do not need to perform this set of
steps. Skip to the next section for calibration of the remote compass.
Because our goal is to endow the EFIS-D10 with a compass that is accurate in all attitudes, our
user magnetic calibration process is more complicated than that for many other products. The
magnetic field vector in North America is predominantly vertical; this requires that any complete
calibration maneuver bank the airplane significantly in order to accurately map out the unique
magnetic signature of your plane in this three-dimensional field. Therefore, a lot of data needs to
be recorded in a variety of attitudes. A PC is required for both storing the data and processing
