11. VIEWING RECORDED MEASUREMENTS AND EVENTS
In order to archive data, the recorder creates a text file with the "csv" extension in the
internal memory or on an
SD/MMC card. The file name contains the device type (AR233), the identification number 16:
ID
, and the date and
time of creation of the file, e.g. „AR233_1_2009-11-30_10-57-16.csv”. The format of a single data record is the
following: “sequential number of the event;date;time;identifier of the event;measurement;internal
temperature;checksum”, An example record for measurement of 2 channels: “30;2009-11-
09;16:34:58;5;149,5;26,2;8BE2”, where the measurement =149,5 and the internal temperature=26,2 °C. The types
and the identifiers of the recorded events are:
−
measurement (identifier of event
5
)
−
connection to the USB port (
0
, “USB;CONNECTED”)
−
disconnection from the USB port (
1
, “USB;DISCONNEC”)
−
loading of new configuration parameters (
3
, “NEW;ON-LINE” or “NEW;OFF-LINE” )
−
creation of a new “
csv
” file (
4
, “ID;xxxx”, where xxxx - value of parameter 16:
ID
of the device)
−
low battery voltage, below 3.35 V (
6
, “LVBAT;x.xx”, where x.xx - battery voltage [V])
To make a presentation of recorded results in a graphic form or as a text, and to print them, the ARSOFT-WZ3
software must be used; the software also enabled detecting unauthorized modifications of the archive. As an
alternative, “csv” files can be edited in spreadsheet software (OpenOffice Calc, Microsoft Excel, etc.) and in text
editors (Windows WordPad, +, etc.).
NOTE:
!
If the SD/MMC card is installed or removed in the course of recording, a new "csv" file is created where the
sequential numbers of events are continued from the previous file.
12. MESSAGE AND ERROR SIGNALING
a) measurement errors recorded in the “csv” archive file in the measured value field:
Code
Possible causes of error

−
the measurement range of the sensor is exceeded from the top
−
the sensor is broken
−
the sensor that is connected is different than the one that is set in the configuration (chapter 9.3,
parameter 5:
inp
)
-19999

Description of message
READ/
WRITE
−
writing to/reading from the internal memory or the SD/MMC card (also during recording of a
measurement)
−
recording is active (a short flash every 10 seconds)
STATUS
transmission through the virtual COM port (used in ARSOFT-CFG WZ1, item 1 of chapter 9)
copying of the configuration file from the SD/MMC card to the recorder and transfer of files with
recorded data onto the card after the
“COPY”
button is pressed (chapter 10
full memory that prevents saving recorded data in an archive file - a quick flash during attempted
recording of measurement
too low battery voltage (less than 3.35 V) - short flash every 10 seconds when recording is active (also
a record is created in the archive file, chapter 11)
