While in historical review mode:
Recording of new data continues unless stopped from the
Logging
menu – see Section 5.1, page 49.
The current value is replaced by '– – –' when the historical data is
invalid (for example, when recording was stopped).
If the trace at the cursor position represents more than one sample,
the indicators flash between the maximum and minimum values of
those samples.
Menu options remain active – enabling the screen interval to be
changed, different scales and channels to be selected, etc.
Operator messages generated are added to the Alarm Event log at
the present time, not the time indicated by the cursor.
All data stored in the recorder's internal memory can be viewed.
The display can be scrolled back to the start of the oldest data.
Archiving to removable media is suspended but all data recorded in
the internal memory buffer during this time is archived automatically
on exiting Historical Review mode.
