A ready-for-use USB-Stick is attached to each equipment, which is
delivered with the option V253-USB.
A new USB stick must be formatted with the file system FAT before
usage. Please perform this using your PC.
If during the writing procedure a malfunction of the USB-Stick is
encountered, the instrument issues an error message
“USB-Stick
error”
on the display and the storage operation is discontinued.
The files which hold the measured values are being stored in the
subdirectory "DATA" of the USB stick. If the subdirectory does not
exist, it will be generated automatically. The filename consists of the
actual calendar date in the form YYMMDD and the ending CSV.
The file directory will look like:
e.g.
070901.CSV
File of 01.09.2007
070902.CSV
File of 02.09.2007
.
.
071006.CSV
File of 06.10.2007
If calendar date is changing, a new file with the new date will be
generated.
The values are stored after each completion of the configured
averaging interval. The values are stored in the following format:
dd:mm:jj;hh:mm:ss;0000,0;0000,0;0000,0;00000;00,0;0;0;9999; CRLF
(Date;Time;Zone1;Zone2;Zone3;Patm;tBOX;C;E;SN; CRLF)
where
Patm
is atmospheric pressure [mbar],
tBox
is the instruments temperature [°C],
C
is a code for measurement unit [ppm=1, mg/m
3
=2],
E
is an Error Code,
SN
is the instruments serial number.
The error code is masked by ASCII code, starting with 65, that is the '
A
'.
The channel, which was active, when the error occured, is marked
with a value of '
999999
' in the error record.
