DATA FORMAT
Introduction
Every data obtained from device have 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 delivered PC software, file structure
must
be the same
as described below,
–
If not stated otherwise, all data is a text in which subsequent columns are separated
by 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 is an end of 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 other value than 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
First column is channel ID (channel number – 1 in decimal notation). In 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
).
