TORAGE SIZE
Commercially available USB 2.0 / 3.0 memory sticks can be used. It is recommended to exclude branded
products - no "promotional items" with your own logo imprint.
There are no speed requirements. Memory sticks that are advertised as particularly fast offer no (!)
advantage in the Avisaro data logger. Typically these optimizations are designed for cameras etc..
Memory sizes from 4 to 256 GByte are supported. As file system FAT or FAT32 (preferred) is used. NTSF
or others are not supported.
Memory sticks are typically not in the scope of delivery - each application typically has different
requirements.

ORMATTING
Usually, sticks come pre-
formatted, so you don’t have t
o do anything. Even larger than 32GByte sticks
are preformatted with FAT32.
Sticks equal or smaller than 32 GByte can be formatted with Windows Operating system as it is. Use
“FAT32” as the desired format.
Windows Operating System does not allow to format sticks larger then 32 GByte with the FAT32 file
system. Usually, sticks come pre-
formatted, so you don’t have to do anything. If there is a need to
reformat a stick, the Avisaro Device can be used.
Please refer to later chapter “Configuration: PC
Companio
n Software” .. “USB Storage” ether in this document, or in the overall “User Manual Serie 4.0”
document.
Alternatively, third party tools for Windows can be used to format large USB sticks. Please note: Avisaro
can not support those third party tools.

HOOSING THE RIGHT MEMORY STICK
For
industrial
use, special parameters may have to be observed.
The
temperature
range should be considered. There are "industrial grade" memory sticks available -
often designed as "SLC" version - which are also suitable for harsh environments.
The
mechanical dimension
should also be considered. It is disadvantageous if the stick protrudes openly
from the housing and could be knocked off. In this case short sticks are recommended. If the logger is
installed protected, then a longer stick is easier to use.
