Read the primary altimeter value. Rotate the CODE knob either clockwise or
counterclockwise until the altitude displayed on the KGX control panel matches the
aircraft primary altimeter. Press ENT and the display will move to the test altitude
screen which is the next configuration item in the configuration mode.
(b)
To complete the testing you must leave the KGX control panel displaying the encoder
altitude, and exercise the altitude on the static test set across the altitude range of the
aircraft. The display will be as shown in Figure 3081 for pressure altitude reported.
(c)
Use at least 10 test points, and verify that in each case the altitude displayed on
the primary altimeter and the altitude displayed on the KGX control panel correspond
within the 125-foot tolerance. Lightly tap the altimeter at each test point to eliminate
friction effects.
