DATA FORMAT
Introduction
Every data obtained from the device has a fixed text format. This format can be
expanded in the future with backwards compatibility.
Here are some principles that are used in the generated data:
–
To download data manually and load into the delivered PC software, the file structure
must be the same
as described below,
–
If not stated otherwise, all data is a text in which subsequent columns are separated
with tabs,
–
If not stated otherwise, all index numbers are counted from zero,
–
All text data have a standard Unix line ending - make sure to convert them correctly
under Microsoft Windows® systems,
–
Do not assume that at the end of the file where is an end of a line character, despite
its possible presence,
–
If not stated otherwise, all dates are stored in the following format (24-hour clock):
YYYY-MM-DD hh:mm:ss:zzz where:
•
YYYY
— year,
•
MM
— month,
•
DD
— day,
•
hh
— hour,
•
mm
— minute,
•
ss
— second,
•
zzz
— fraction of a second,
Current measurements data format
Text data have two columns:
–
channel index
(in decimal notation),
–
channel value
(decimal point is a dot) – There can be another value than a number:
•
-inf
indicates that the channel is in
-LO-
state,
•
inf
indicates that the channel is in
-HI-
state,
•
nan
indicates that the channel value is unspecified (e.g.: channel is in
ERR
state or is disabled),
Example:
channel 1 to 6 measurements.
0 1.003
1 2.234
2 -inf
3 inf
4 nan
5 123.223
The first column is channel ID (channel number – 1 in decimal notation). In the second
column channel 3 (ID =
2
) is in -LO- state (
-inf
), channel 4 (ID =
3
) is in -HI- state (
inf
) and
channel 5 (ID =
4
) is in ERR state (
nan
).
