Scanner Digital Display
Located under the Scanner bar graph area is the alphanumeric display. It
displays alphanumeric values for different parameters as well as status
and alarm messages.
Normalize / Standard View
To toggle between Standard and the Normalize views, hold the
LF
button
for three seconds until the
NRM
icon toggles on or off. Note: Normalize
cannot be activated while in Lean Find mode.
Standard view
(when the
NRM
icon is
not
lighted): the EGT
represent absolute temperature. The top of the columns indicate
absolute temperature relative to the adjacent range mark
temperature scale. A maximum height column depicts the
temperature at the top of the range mark scale (or more), while no
column represents the temperature at bottom of the range mark
scale (or less). The
Standard view
permits comparison of EGTs
across all
cylinders.
Normalize view
(when the
NRM
icon is lighted): the EGT represent
the difference in temperature from the mid-point of the range mark
scale. When you change to the Normalize view, all EGT columns are
initially normalized to the mid-point for deviation trend analysis. Any
changes are shown as an increase or decrease relative to the mid-
point, thus giving an instantaneous indication that an EGT has
deviated. You normally use normalize in level cruise, but it is also
useful during steady state run-ups. Note: A common misapplication is
to be in the Normalize view and then change power setting. This
causes all columns to go off scale, high or low. Select Standard view
before changing power or altitude.
