Voice memo/marker
The voice memo function allows the operator to add comments before and
after the recording procedure or during recording. The marker function can
be used to mark a certain position, for example when a particular phenom-
enon occurred during recording. This makes it easy to later locate the data
for that point. For example, if noise was encountered at a certain point, the
marker can serve to locate and isolate the corresponding data.
Voice memo
While voice memo is activated, the sound picked up by the voice memo
microphone connected to the Voice Input connector can be recorded. When
the “Inp” item for CH5 in the <Input> menu is set to “Voice Memo”, the
indication
appears to the right of the bar graph.
The level of the voice signal is shown by the bar graph for channel 5. Pressing
the switch on the voice memo microphone activates voice memo recording.
Releasing the switch stops voice memo recording.
Marker
The marker function is only available during data recording. The maximum
number of marker points that can be set between the beginning and the end
of data recording is about 3,000.
When the “Inp” item for CH5 in the <Input> menu is set to “Marker”, the
indication
appears to the right of the bar graph.
When the microphone switch is pressed, the indication
fl ashes for one
second.
The marker precision is about 1 second.
