7.1 SD Cards

There are two methods of archiving to an SD card:
An SD card is kept in the analyzer
Data is copied automatically to the SD card at set
intervals. The SD card is then swapped periodically for an
empty one.
Depending on how the configuration has been set, data is
added either to the card until it is full and then stops
archiving or the oldest data on the SD card is overwritten
by the newest.
Note. To set up the analyzer to archive data to an SD
card automatically – see Section 6.6.3, page 38.
It is advisable to back-up critical data stored on an SD
card regularly. The analyzer's internal memory provides a
buffer for the most recent data so if data stored on an SD
card is lost, it can be re-archived – see Section 7.2,
page 44.
Data is copied to an SD card when required
An SD card is inserted into the analyzer and a prompt is
displayed asking the user to select the unarchived data to
be copied – see Section 12, page 56.
