USB Key Memory Dump
The large USB (Type A) port on the right side of the instrument with
“
MEM
”
(Memory) is used only for dumping a data file onto a USB
memory key, it has no other function. General USB connectivity and
external charging are achieved with the other micro USB port.
The instrument only detects the presence of a memory key when in
memo
ry mode, at which point “USB” shows on the LCD
if a stick has
been detected.
•
To save memory to USB stick, enter Memory mode, then
insert USB stick, and observe that “USB” shows on the
display to indicate that the USB stick has been detected.
•
Press the triangular button above the LCD. Do not remove
the USB stick until the download has completed and the
instrument stopped beeping.
The file name on the USB key will auto-increment with each memory
dump. So successive memory dumps can be made without over-
writing the previous files.
This gives the instrument effectively infinite autonomous test capacity,
e.g. the instrument memory can be repeatedly dumped and cleared.
The saved file incorporates a checksum which is used by
KITS™
to
check the file integrity, and to detect tampering with the file.
