• When a USB ash drive is being accessed, the color of the USB icon changes from
blue to red. Do not turn off the power of the instrument while the USB ash drive is
being accessed. Also, do not remove the USB ash drive from the instrument while it
is being accessed. This may result in the loss of data stored in the USB ash drive.
• Do not transport the instrument while a USB ash drive is connected. Damage could
result.
• Some USB ash drive are susceptible to static electricity. Exercise care when using
such products because static electricity could damage the USB ash drive or cause
malfunction of the instrument.
• With some USB ash drives, the instrument may not start up if power is turned on
while the USB ash drive is inserted. In such a case, turn the power on rst, and then
insert the USB ash drive. We recommend that various operations such as copy and
save be carried out with the USB ash drive before using it for actual measurements.
CAUTION
USB ash drives have a limited usable lifetime. Data reading and writing will fail after long-term
use. Replace the USB ash drive in this case.

strap is recommended when disconnecting the interface.)
• To avoid equipment failure, do not disconnect the communications cable while
communications arein progress.
• Use a common ground for both the instrument and the computer. Using different
ground circuits will resultin a potential difference between the instrument’s ground and
the computer’sground. If the communications cable is connectedwhile such a potential
difference exists, it may result inequipment malfunction or failure.
• Before connecting or disconnecting any communications cable, always turn off the
instrument and the computer. Failure to do so could result in equipmentmalfunction or
damage.
• After connecting the communications cable, tightenthe screws on the connector
securely. Failure to secure theconnector could result in equipment malfunction or
