Arexx BS-750SD Mode D'emploi page 18

SD card
Initially the SD card must be formatted. Often cards which already
have been formatted are delivered, but if needed you can also
format a card by PC-software. In using SD-cards for the BS-750SD
it is important to create a directory 'log' at the SD-card (if no such
directory already exists) as a location to store the logging files.
At the log-directory the system will generate a text file for each sen-
sor and each month.
The naming convention for the log-files is:
m<id><year><month>.txt
in which
id:
E
N year:
month:
G
All data which refers to the file-name's criteria will be added to the
relevant data-file.
L
A data file starts with a file header, followed by individual lines for
each data-record for one measurement data set.
I
<time-stamp>, <value>
in which
S
time-stamp: yyyy-mm-dd hh:mm:ss (UTC)
H
value:
Delivered from an SD-card these data sets can also be imported to
a PC and processed with e.g. Excel-software. The SD-cards' data
however also can be imported to the logger software. Import from
the SD-cards to the logger software can be controlled by the import
function – see menu: file --> import.
