10. CREATING AND REVIEWING RECORDED MEASUREMENTS AND EVENTS
In order to archive data, the recorder creates text files with the extension
csv
in the internal memory.
Subsequent, new archive files (csv) are created in the following situations:
- when the new recording starts (e.g. when the
Recording type
parameter
=
periodic daily (hourly)
, new files are created
daily, chapter 9.2)
- when the memory is full with simultaneous deletion of the oldest archives (provided that the parameter
Type of archive
saving
=
circular (endless)
, in the recording options)
- after changing the time and/or date (chapter 9.1) and other parameters such as:
Archive identification number (ID),
1-st
or
2-nd channel logged value
(table 9.2),
Temperature scale type
(chapter 9.3)
- after replacing the battery (only if the recording is on, additionally set the time and date, chapter 9.1)
The file name contains the device type (AR23x.B or.BT),
Archive identification number (ID)
and the
date and time of
creation, e.g. "AR236.B_1_2018-01-01_10-57-16.csv "(AR236.B, ID = 1, date = 2018-01-01, time = 10:57:16).
The format of a single data record is as follows: "event sequence number; date; time; event identifier; argument 1;
argument 2; check sum". Sample record for humidity and temperature measurement:
“20;2018-05-09;13:46:30;5;40,4;26,3;IEM1”, where argument 1 = 40.4 %RH, argument 2 = 26.3 °C.
Types and identifiers of recorded events:
- measurement (event

ID)
- connection to the USB port (event
0
, "USB; CONNECTED")
- disconnection from the USB port (event
1
, "USB; DISCONNECT")
- loading a new configuration (event
3
, "NEW; ON-LINE" from ARSOFT-CFG or "NEW; OFF-LINE" from the file
AR23x.B.cfg/AR23x.BT.cfg
)
- creation of a new "
csv
" file (event
4
, "ID; xxxx", where xxxx -
Archive identification number (ID)
of the
device)
- low battery voltage, below 3.1 V (event
6
, "LVBAT; x, xx", where x.xx - battery voltage [V])
- pause (holding) of recording with the
STOP
button (event
10
, "REC; PAUSED")
- resuming the recording with the
START
button (event
11
, "REC; RESUMED")
For graphic or text presentation and printout of recorded results, you can import data into the ARSOFT-LOG program via
the computer's USB port. If the recorder disk is not available (parameter
Access protection
=
full
or
for files only
, chapter
9.4), enable in the program
Options
and use the
"Unprotect and load via USB
" button, and then follow the instruction ma-
nual. ARSOFT-LOG additionally allows you to detect unauthorized modification of the archive by verifying the check sum.
Alternatively,
csv
files can be opened in any spreadsheet (e.g. OpenOffice Calc, Microsoft Excel), as well as in various word
processors (Windows WordPad, N+, etc.).
11. SIGNALING MESSAGES AND ERRORS
The messages appearing on the LCD display are temporary (with a duration of 4-9 seconds) or continuous. To shorten the
presentation time or delete the message, use the
F
and/or
START/STOP
buttons.
