During the operation, the PCE-P30U transducer creates folders and files
on the SD/SDHC memory card or in the internal file system memory. An
example folder structure is shown on fig. 27.
Fig.27. Folder structure on the memory card (internal file system)
Apart from the ARCH folder where recorded data are stored, also the
SYSTEM folder is created on the memory in which the
start.txt
file is
stored to save the date and hour of installation of the memory card
(also when starting the device after the power supply has been lost).
Data on the memory card or internal file system memory are stored as
files located in folders corresponding to the device name and serial
number – see fig. 27. File names correspond to the date of recording
and have the following format
XXXX_Y.Dzz
, where
XXXX
→ year ,
YY → month. Extension of files have following format: Dzz, where „zz”
is subsequent number of file from the same month.
For example, first
archive file in May 2014 will have name: 2014_05.D00, subsequent
file: 2014_05.D01 etc. There can be created maximum 32 files for
each month (*.D00 … *.D31). FIle number is changed automa
-tically
after reaching 12 MB file size if one or two values are recorded
Disp.Val
or
+2nd Val
.
If
transducer is configured for recording displayed
value, second displayed value and all queried values, the
maximum
file
size
is calculated by transducer itself and depends on the number of
queried values.
