Enter channel assignment information, using the first Propeller
Balance Setup screen that displays.
NOTE: The user may change the channel assignments by
pressing the appropriate context key, if the installation for
the subject aircraft is different from the default settings.
This action allows the user to select the user’s own channel
assignments.
After the user makes sure the channel assignments shown on the
Propeller Balance Setup screen are the same as the actual
channels used, press START to advance to the next screen.
CAUTION: We suggest that the user perform a check run,
both on the first run and after the front balance channel is
within limits. If the rear channel is higher than the original
reading after the propeller is balanced, further testing is
necessary to find out the possible cause. The problem could
be a propeller out of track or an imbalance in the power
train rotating components (crank shaft). Do not balance
under this type of condition. Select channels 2A for a rear
check Velocimeter, if the user is using one.
