5.5.4 Archive File Types
Archive files created by the instrument are given filenames
automatically. Each type of archived file is given a different
filename extension as shown in Table 5.1.
5.5.5 Archive Filenames
Archive filenames are formatted as shown in Table 5.2.
5.5.6 Channel Data Files
A new channel data file is created under the following
conditions:
On power up.
When the current file for a channel does not exist on the
media card.
When the maximum size (5Mb) of the existing data file is
exceeded.
When the recording channel's configuration is changed.
When the daylight saving period starts or ends.
Files containing channel data generated during the daylight
saving period have “~DS” appended to the filename.
Example 1
– Start of daylight saving period:
Archiving is started at 01:45:00 on 30th March 2003 –
filename: 01450030Mar03Ch1_1AnlgSM3000.B00.
Summertime starts at 2:00am on 30th March 2003.
The clock changes automatically to 3:00am. The existing file
is closed and a new file is created – filename:
03000030Mar03Ch1_1AnlgSM3000~DS.B00.
The file '01450330Mar03Ch1_1AnlgSM3000.B00' contains
data generated from 01:45:00 to 01:59:59 (before
summertime starts).
The file '03000030Mar03Ch1_1AnlgSM3000~DS.B00'
contains data generated from 03:00:00 (after summertime
starts).
Example 2
– End of daylight saving period:
Archiving is started at 00:15:00 on 26th October 2003 –
filename: 00150026Oct03Ch1_1AnlgSM3000~DS.B00.
Summertime ends at 3:00am on 26th October 2003.
The clock changes automatically to 2:00am. The existing file
is closed and a new file is created – filename:
02000026Oct03Ch1_1AnlgSM3000.B00.
The file '00150026Oct03Ch1_1AnlgSM3000~DS.B00'
contains data generated from 00:15:00 to 02:59:59 (before
summertime ends).
The file '02000026Oct03Ch1_1AnlgSM3000.B00' contains
