Archiving (Cont.)
Rate Allows the user to specify the frequency at which the contents of the Flash memory
are archived to the USB port or, via FTP, to a pc. Scrollable settings are:
None Automatic archiving is disabled. Any archiving must be initiated by
the user using Demand Archiving, as described in Section 4.3.7
Hourly Archive occurs on the hour, every hour.
Daily Archive initiated at 00:00* each day
Weekly Archive is initiated at midnight* every Sunday
Monthly Archive is initiated at 00:00* on the 1st of every month.
Automatic The recorder selects the least frequent of the above archive periods
which is guaranteed not to lose data as a result of the internal flash
memory’s running out of space.
*Note: Archive times are not adjusted for daylight saving time (DST). Thus, if the archive is set to
‘Daily’, ‘Weekly’ or ‘Monthly’, then during summer time, the archive will be triggered an hour late
(i.e at 01:00 hours instead of midnight).
Destination Select ‘FTP Server’ for archive to a remote pc, or ‘USB’ to archive to the USB port
device.
File format Select ‘Binary (UHH)’ ‘CSV’ or ‘Both’.
Binary (UHH)
A proprietary format used by the instrument that needs other
software (e.g. Review’, to interpret the data before it can be
presented in spreadsheets etc. Binary files have the extension ‘.uhh’.
CSV This format is a standard open-file format for numeric data. A simple
ASCII-based format, it is readable by a wide range of pc applications as
well as being suitable for direct import into many commercial
databases. CSV files have the extension ‘.csv’.
Both Archiving includes both .uhh and .csv files.
Note: CSV is ASCII based and cannot interpret Unicode characters. For this reason, some
characters available to the user will not be displayed correctly in .csv files.
CSV Values Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then
process values are included in the file (see figure 2.2.2b for details).
CSV Messages Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then
messages are included in the file (see figure 2.2.2b for details).
CSV Headers Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then
Header details are included in the file (see figure 2.2.2b for details).
CSV Headings Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then
column headers are included in the file (see figure 2.2.2b for details).
CSV Date Format Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. Allows ‘Text’ or ‘Spreadsheet’
to be selected. Text causes a time/date to appear in the spreadsheet. ‘Spreadsheet
Nu’ displays the number of days since December 30th 1899. The decimal part of
the number represents the latest six hours. For example: DDD--- --DD.25
represents 06:00 hours and DDD--- --DD.5 represents 12:00 hours. Spreadsheet
Numeric format is more easily interpreted than ‘Text’ by some spreadsheet
applications.
CSV Tab Del Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’.
CSV (Comma Separated Variables) does not always use commas as separators. For
example, in some countries the decimal point is represented by a full stop (period),
whilst in others a comma is used. In order to avoid confusion between a comma as a
decimal point and a comma as a separator, a different separator can be used. This
field allows the ‘tab’ character (^t) to be used instead of a comma.
