IM/SM500F Rev. Z
Note.
While in Historical Review mode:
Recording of new data continues unless stopped from the Logging Menu –
see Section 5.1, page 47.
The current value is replaced by '– – –' when the historical data is invalid
(e.g. when recording was stopped).
Where 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 – allowing 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.
Select to move to data stored in the recorder's onboard memory that was recorded
at a specific date and time.
Note.
If daylight saving is enabled (see Section 7.6.3, page 76)
and
the selected
'Goto' target date/time is within the daylight saving period, 'Daylight Saving'
is displayed on the dialog box.
Once internal memory becomes full, the oldest data is overwritten by the
newest data. If historical review has been selected for some time, the oldest
data present may no longer be available.
The recorder exits Historical Review mode automatically after 15 minutes if
no key is pressed.
