Before Connecting Measurement Cables
• To avoid electric shock, turn off the power to all devices before plugging or
unplugging any cables or peripherals.
• Be sure to connect the voltage input and current input terminals correctly. An
inc
orrect connection could damage or short circuit this instrument.
• In order to prevent electric shock or device damage, observe the following pre-
cautions when making connections to the external control terminals and other
int
erface connectors.
•Turn off the instrument and any equipment being connected before connect-
ing the measurement cables.
•Exercise care not to exceed the ratings of external control terminal and inter-
face connector signals.
•Make connections securely to avoid the risk of connections coming loose
during ins
trument operation and bringing wires into contact with other electri-
cally conductive parts.
•Ensure that devices and systems to be connected to the external control ter-
minals are properly isolated.
• To avoid electric shock and short-circuit accidents, use only the supplied voltage
cords to connect the instrument input terminals to the circuit to be tested.
• To avoid equipment failure, do not disconne
ct the communications cable while com-
munications are in progress.
• Use a common ground for both the instrument and the computer. Using different
ground
circuits will result in a potential difference between the instrument's ground
and the computer's ground. If the communications cable is connected while such a
potential difference exists, it may result in equipment malfunction or failure.
• Before connecting or disconnecting any communications cable, always turn off the
in
strument and the computer. Failure to do so could result in equipment malfunction
or damage.
• After connecting the communications cable
, tighten the screws on the connector
securely. Failure to secure the connector could result in equipment malfunction or
damage.
