3.1.5 EGT / CHT display section

The XTreme supports up to 12 thermocouples for EGT / CHT. The EGT / CHT section will automatically try and
maximize the display area according to the number of EGT / CHT selected. The EGT / CHT parameters can be
configured in the

“EGT SETUP”

and

“CHT SETUP”

menu.

The EGT / CHT number will highlight to the indicated the temperature value if

“HIGHEST”

is selected. The EGT highlight

color is magenta, and the CHT color is cyan.

EGT / CHT Trend graph

The EGT / CHT trend displays can be accessed by pressing the 2

left most button when the engine display screen is

shown. The trend graph displays the last 250 seconds of EGT/CHT temperature readings.
