Chapter. 3 Recording
3.8.8. RANDOM MANUAL Mode
RANDOM MANUAL mode is a trigger mode, similar to RANDOM mode, where each time a trigger
is input only a predetermined number of frames are saved to memory. The difference between this
mode and RANDOM mode is that in RANDOM mode the number of specified frames are recorded
directly after the trigger input, whereas in RANDOM MANUAL mode, at the timing of the trigger input,
the frames before and after the trigger, each specified as desired, remain in the recording memory.
For example, this function is convenient for a subject which is an irregular and repeated
phenomenon which can have a trigger output produced for each cycle or occurrence, and you want
to check the action before and after the trigger timing. The number of frames recorded each time the
trigger is input can be set as desired, in one frame increments, from one frame to the maximum of all
the recordable frames available.
•
Setting the RANDOM MANUAL mode record count
Setting the record count in RANDOM MANUAL mode is the same as setting the record count for
RANDOM CENTER mode.
•
Setting the RANDOM MANUAL mode frame count
To use RANDOM MANUAL mode, the proportion of frames to record before and after the trigger must be
set in advance before recording.

For how to setup of RANDOM Mode, refer to “3.8.5. RANDOM Mode”, page 37.
