RMS recorder
NOTE
In the RMS recorder function, a trigger can be accepted
immediately from the start time. In some cases, therefore, the
pre-trigger portion of a recording may not be available.
In Memory recorder function, when the pre-trigger is set, the
trigger will not be registered for a certain period after the start
of measurement. (During this interval,
Pre-trig wait
is shown on
the Waveform Screen.)
With instantaneous waveform recording using the RMS recorder
function, the pre-trigger portion of the waveform may not be
recorded even if pre-trigger is selected because triggers are
accepted starting at the moment that RMS recorder measurement
begins.
When the trigger can be registered, the indication
Wait for trig
is
shown on the Waveform Screen.
