of the readout is 1 PSI. The display digits change color as a
function of oil pressure as defined below:
RED O PSI < OIL PRESS < 16 PSI
AMBER
16 PSI ~ OIL PRESS < 30 PSI
WHITE 30 PSI ~ OIL PRESS
(b)
Engine Oil Temperature (OIL TEMP) Display - The engine oil
temperature is displayed digitally
in white in the second row
of the secondary engine parameter display (Figure 223). The
resolution of the digital readout is 1 "C. The display digits
change color as a function of oil temperature as defined below:

OILTEMP < -40 "C
AMBER -40 "C < OIL TEMP < -30 "C
WHITE
-30 "C ~ OIL TEMP < 105 'C
AMBER 105 "C < OIL TEMP < 120 'C
RED 120 "C < OIL TEMP
(c) Engine Vibration Monitor (EVM) Display - The EVM displays
(Figure 223) consists of two sets of windows (row 3 and 4)
labeled LP and HP respectively. EVM is displayed digitally in
