Limits” on page 44.
 Cylinder Numbers and Dot Index
A row of numbers 1 through 6 and the letter T are the column labels for
the analog display. The 1 through 6 are the cylinder numbers. If the TIT
option is installed, the T denotes the last column is displaying Turbine
Input Temperature (TIT). If the T is absent and the Oil temperature
option is installed, the last column displays Oil temperature. If both TIT
and Oil temperature options are installed, the last column displays TIT
and the missing segment displays OIL. A round dot under the numbers 1
through 6 indicates that particular column is shown numerically in the
EGT and CHT digital display.
 Normalize and Percentage View Indicators
•
Percentage view: when there is a P at the top of the display,
the columns indicate percent of EGT red line. Each column is
composed of a stack of segments. A maximum height column
depicts 100 percent of red line and a one segment-high
column depicts 50 percent of red line. For example, if the red
line is 1650°F, a maximum height column represents 1650°F
and a one segment-high column represents half that value, or
825°F. The Percentage view permits comparison of EGTs
across all cylinders. Hotter cylinders display higher columns
than cooler cylinders.
•
Normalize view: when there is an N at the top of the display,
the EGT columns are displayed normalized. When you
change to the Normalize view, all column peaks are set to the
same half-height level for trend analysis. Any changes are
shown as an increase or decrease in column height. A one-
segment change in column height represents a 10°F change.
The Normalize view permits rapid visualization of EGT
trends, rather than a percentage of red line. You may use
normalize in level cruise.
To toggle between Percentage and the Normalize views, hold the LF
button for three seconds. The analog display becomes half height and the
display changes to the Normalize view. Selecting the Normalize view does
not affect the digital display nor alter the measurement sequence. The
