.3 Setting the Pre-trigger (Memory Recorder and RMS
Recorder Functions)
・The pre-trigger function serves to record the waveform not only after but also
before triggering has occurred.
・In the memory recorder function, using the recording start point as 0% and
the recording end point as 100%, the trigger point can be specified in percent.
In the RMS recorder function, using the recording start point as 0 DIV, the
trigger point can be specified in DIV (0, 5, 10 DIV).
