The information screen below will be displayed if you are running an N1 DEEC
equipped engine. The message is to inform you that all power adjustment will be
made automatically by the Viper II Analyzer. While you do not need to adjust power
for the calibration run, you still have the ability to reduce the engine power using the
PLA if necessary, such as in an emergency or because of airfield traffic. If power is
reduced, the analyzer will afford you the opportunely to continue the run without
returning to the beginning of the run. Press [F5] to acknowledge and continue.

The STABILIZATION screen, shown below, will be displayed. This screen will be
displayed while the engine is in the stabilization mode and will automatically advance
to the acquisition mode when the engine is thermodynamically stable. The length of
time this screen is displayed will vary according to the quality of the data being
collected. Note the P/Set: 1 indicates this is the first of the five power point settings.
Pressing the [F1] “Page #2” key will display the additional fields of “N1 Bar RPM”
and “N2 Bar RPM”. Pressing the [F5] “Abort” key will terminate data acquisition.
