Field mountable paperless recorder 4 Operation
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.
