8. OPERATION AND FEATURES OF SD/MMC CARD
SD/MMC card to store data may be particularly useful for stationary (on-wall) installations of the recorder
and when the amount of measurement data to be stored exceeds the capacity of the internal storage.
Properly installed card in the "
SD/MMC CARD
" slot has the following features:
- store files with values written to the files during recording
- off-line parameter configuration (using a configuration file
AR236.cfg
or
AR232.cfg
with "
COPY
" button,
see section 7)
- move archive
„csv”
files from internal storage onto the card (the action may be performed by pressing
"
COPY
" button and authorizing or when authorization request is disabled; during the operation
"
STATUS
" indicator is illuminated; timing for 4 MB of data - up to 2 min.)
NOTE
:
- the action of moving
„csv”
files from internal storage to SD/MMC card is performed
CONCURRENTLY
with off-line configuration. Thus, to avoid undesired recorder reconfiguration, make sure that on the card
exists appropriate "
.cfg
" file (or the file does not exist if
Prot
=
disabled
)
- use only branded SD/MMC cards (e.g. SanDisk or Kingston) formatted using FAT 16 file system for
maximum battery durability
-
cards with capacity over 2 GB may cause device suspension, which requires removing batteries
for a while
