holding a frame, all data readings are locked at the last readings before pressing

RECORDING A MOVIE
A lengthy data movie can be recorded. Recording time will take from a few seconds
to several minutes, depending on the baud rate (speed) of the vehicle ECU and
the parameters set with the Custom Data List, (if applicable).
To record a movie, first select
“
Codes & Data
”
. Press
N
for the
“
Exit
”
menu and
choose
“
Arm Movie
”
from the
“
Exit
”
options. Pressing
Y
to arm the movie erases
any earlier movie in the Scanner and returns to the previous data mode. The top
line of the display looks like this:
ARM indicates that the movie is armed and will be triggered when
Y
is pressed.
When the movie is armed, the
Y
button no longer holds a single frame of data. It
now acts as a trigger for the movie recording. Press
Y
to trigger the recording of
the last frames at any time. The movie will record 75 % of the data frames that
occur before pressing
Y
and 25 % after. The frame count starts when the
Y
button
is armed to trigger the movie. If the engine is not run long enough for the ECU to
transmit 75 % of the data frames after arming the movie, the movie length before
the trigger point will be shorter than the 75 % frame maximum. When
Y
is pressed
to start the movie, the top display line looks like this:
