To calibrate the altimeter so that the barometric pressure it registers is correct, the follow procedure
should be followed. This procedure must be performed with a new instrument, and should be re-
checked on an annual basis.
a) Turn on the instrument and allow 5 minutes or more for its internal temperatures to stabilize.
b) Using the Altimeter Set page, set the altimeter so that the barometric pressure display matches the
current altimeter setting. Note that this is the 4 digit number immediately after the ALT label on this
set page. No decimal point is provided, so an altimeter setting of 29.92 will be displayed as 2992
c) Adjust the ALTCor setting on the configuration set pages so that the altitude display (in feet)
matches the local elevation. The nominal value of the ALTCor is 128. Increasing this number by one
will change the altimeter display by 6 feet.
d) If your ALTCor falls outside the range of 50-200, you may have made a mistake in your
calibration.

AltSF, 1 (10k), 2 (20k), 3 (30k), 4 (40k) Altimeter Adjustments (SW Version 5.8 and above)
These entries are provided to allow precision calibration of the altimeter. To prevent inadvertent
alteration of these entries, they can be accessed only by setting the Max Volts limit to 0.2. These
entries will appear immediately after the ALTCor setting. To perform the calibration, set the Max
Volts limit to 0.2, and follow the "Precision Altimeter Calibration Procedure" in the following section.
7.14.1
Precision Altimeter Calibration Procedure
1) Set the "AltCor" as described above.
2) Connect an air data test set to the airplane. Be sure the pitot connection is secure, as damage to the
airspeed pressure sensor could occur if the pitot connection from the air data test set becomes
disconnected during this calibration.
3) Set the air data test set altitude to an altitude near the airplane’s ceiling. Use the “AltSF” adjustment
to correct the displayed altitude so that it matches the altitude selected on the air data test set. Be sure
the altimeter (baroset) setting on the test set agrees with that altimeter (baroset) setting in the EFIS.
4) Set the air data test set to an altitude near sea level. Change the “AltCor” to correct the altimeter
reading.
5) It may be necessary to repeat steps 3 and 4 a few times, as there are some interactions between
these adjustments.
6) Set the air data test set successively to 10,000', 20,000', etc, and use the corresponding altimeter
adjustment (1 for the 10,000' adjustment, 2 for the 20,000' adjustment, etc) to make any correction
necessary at these altitudes.

User Definable Combination Pages
7.15.1
1D1, 1P1, … GD9, GP9
These entries are used to setup your user-definable combination display pages. They are used in pairs
(although they appear to 2 successive screens), with the first item of the pair defining the data to be
displayed (thus the “D” in the label), and the second item defining the position (thus the “P” in the
label) of the item. Two sets of twelve pairs of entries are used to allow up to twelve items to be
displayed on each of 2 user-definable combination pages. Nine pairs of entries are provided to allow
up to nine items to be displayed on the bar graph pages.
An example of the labels used to identify these page is as follows:
2D1 => 2nd combination page, Displayed item, entry 1
2P1 => 2nd combination page, Position of item 1, entry 1
