Data Transfer
Downloading Measured Data
The
blueberry COMPACT
contains two ring buffer
data memories; one for the statistics, one for the
samples. Actual data overwrite the oldest data lines
which makes the deletion of the memory unneces-
sary.
Select
Archive
in order to display a list of all stored
statistics files. The
blueberry COMPACT
creates
one statistics file per day. These files contain time
series of the statistical evaluations of the samples.
The file name contains the index of the actual meas-
urement, the date and the tag
stat
for ‚statistics‘.
The data logger increments the index every time
the configuration is changed or the data logger
reboots.
Example:
000024_2004-03-19_stat.csv
Select
HighRes
in order to display a list of all stored
samples files. The
blueberry COMPACT
creates one
CSV file per hour. These files contain time series of
all measured samples. The file name contains the in-
dex of the actual measurement, date and time, and
the tag
meas
for ‚measurement‘.
Example:
000024_2004-03-19_15_meas.csv
Downloading measured data works like a download
from an Internet site: click with the right mouse
button on a file, select
Save file as...
from the pull-
down menu, enter the destination path and click
OK
.
CSV files can be imported into data analysis soft-
ware like
WAsP
or
WindPRO
. Double-clicking on the
CSV file opens it directly in
MS-Excel
.
Data Format
The
blueberry COMPACT
stores measured data as
comma separated ASCII files (CSV). Each data file
contains a header which indicates information
about the data logger and the measurement config-
uration: serial number of the data logger, index of
the measurement, site info, measurement functions
and parameter settings. The header is followed by
an empty line and a line with column headers. The
measured data lines have the format: date, time,
period, measured values. Decimal delimiter is a dot
(e.g.,
2.564
), columns are separated by a comma.
