Counter File System
Measurements in volatile reading memory and counter configuration states
can be stored in files within the counter’s internal (non-volatile) flash mem-
ory, or on a external USB memory device connected to the ‘host’ port on the
front panel (Figure 7-1).
Files are created within folders on the root directory, or within sub-folders rel-
ative to the root directory. The relationship of folders and files in internal
flash memory and on the USB drive is shown in Figure 7-2.
