2.3 Connecting Measurement Cables to the Instrument
38
Connecting to the Pulse Input Connector
To avoid electric shock and short circuit accidents or damage
to the instrument, pay attention to the following:
• The ground terminal for the
optional 9641 Connection
Cable is not isolated from
the instrument’s ground
(chassis ground). There-
fore, if the measurement
object connects to AC, it
should have a grounded, polarized plug, and be connected
to the same power outlet as the instrument’s AC adapter.
If the instrument and measurement object are connected to
different mains circuits, or if an ungrounded power cord is
used, the potential difference between the different ground-
ing paths may result in current flow through a connection
cable that could damage the measurement object or instru-
ment.
• Do not apply any voltage that exceeds the rated voltage
(maximum input voltage: 0 V to 10 V) indicated in the speci-
fications.
Damage or heating of the instrument could cause personal
injury.
