Viewing Readings Stored in Memory
During a scan, the instrument automatically adds a time stamp to all
readings and stores them in non-volatile memory. Readings are stored
only during a scan. You can read the contents of memory at any time,
even during a scan.
• You can store up to 50,000 readings in non-volatile memory during a
scan. From the front panel, you can view the last 100 readings and all
of the readings are available from the remote interface. If memory
overflows (the MEM annunciator will turn on), a status register bit is
set and new readings will overwrite the first readings stored (the
most recent readings are always preserved).
• Each time you start a new scan, the instrument clears all readings
(including alarm data) stored in reading memory from the previous
scan. Therefore, the contents of memory are always from the most
recent scan.
• The instrument clears all readings in memory after a Factory Reset
(*RST command) or Instrument Preset (SYSTem:PRESet command).
Reading memory is not cleared when you read it.
