Actron OBD II System Tester 9615 - Manual (Page 3)

3
The tester records for a time of varying duration. Re-
member, your recording will consist of 5 Frames of
data prior to the start of the recording, and a number of
Frames after depending on the number of PID. All
applicable PIDs will be recorded.
The recording progress is displayed for the duration
of the recording. You can record all the frames or press the ENTER key any time to stop
recording.
Next, You will be asked if you want to play back the
recording now. If you answer “YES,” then the Playback
Data function will display, Answering “NO” returns
you to the OBD II Function Menu.
Playback Data (New Function)
The Playback Data function is used to playback a recording. This function is very similar to View
Data. The only difference is that View Data is a real time viewing of vehicle’s PIDs, while
Playback Data is a viewing of previously recorded ones.
To view the PIDs recorded in the Record Data function, select Playback Data from the OBD II
Function Menu. If a recording does not exist in the OBD II System Tester’s memory, then the
message “No Recording Present, Please Make Recording First” will display. The Record Data
function must be performed in order to play back the data. Press the BACK key to return to the
OBD II Function Menu and select Record Data to make a recording.
If recorded data exists, the PIDs, Frame number and
Time are displayed. On the Playback Data screen,
lines 1-3 are used to display the vehicle’s PIDs. Use
the UP/DOWN arrow keys to scroll through the PID
list. The end of the list is reached when only the UP
arrow is displayed at the right of line 3. The PID list
scrolls line-by-line and will not wrap around to the
beginning.
NOTE: Multiple-response PIDs (see View Data) are displayed with their module address in one
frame and their measurement values in the next frame. Use the LEFT/RIGHT arrow key
to alternate between the frames to identify the PIDs and their measurement values.
Use the LEFT/RIGHT arrow key to move through the Frame/Time index. Frame 0/Time 0.0 is
the trigger point; where the recording was started by either Manually Triggering or by Triggering
On Codes. Frames -5 to -1 contain data prior to the trigger point.
NOTE: After reaching the last time interval, the system tester will “wrap” to the first time interval
recorded. The Time display will change from a positive to the first negative number viewed.
This is normal. The LEFT/RIGHT arrow may be used to scroll through all time intervals.
A Frame is a “snapshot” of engine operating conditions at a certain time. The relationship
between the Frame index and the Time index are based on the vehicle’s on-board computer
data rate and the number of PIDs being read. Remember, not all OBD II vehicles use the same
data stream (communication protocol), data rates (baud) and the same number of PIDs. For
this reason, not all vehicles will start and end with the same Frame number. The Frame
number increases every time data is transmitted from the vehicle to the OBD II System Tester.
The intervals when this occurs increases for slower data rates and larger PID lists. Frame 0
occurs at the trigger point, Time 0.0. Thus, negative and positive Frame numbers contain data
before and after the trigger point, respectively.
