4 Be aware of potential
shock hazards during
floating-ground
measurements.
a Do not touch any of the DC subsystem
output connectors when the shorting bar is
disconnected and a floating-ground
measurement is in progress.
b Warn others working in the system’s
vicinity of the potential shock hazards.
• For additional information, see the
following section “Precautions for
Performing Floating-Ground
Measurements.”
5 Before touching the
FORCE, SENSE, or GUARD
connectors, ensure your
safety.
a Switch off the DC subsystem and discharge
the capacitors.
b If you do not switch off the instruments,
complete ALL of the following
precautionary steps:
• Terminate the DC subsystem
measurement by pressing the Stop key
and confirming that the MEASUREMENT
indicator is not lit.
• Deactivate the standby mode (if used) by
pressing the Standby key and confirming
that the Standby indicator is not lit.
• Confirm that the HIGH VOLTAGE
indicator is not lit.
• Open the interlock connection.
6 Never use replacement
fuses with incorrect
ratings.
a After finding the cause of failure, replace
component fuses with fuses of the same
current rating and of the type specified in
the instrument’s product documentation.
• Failure to use correctly rated fuses
could result in a fire hazard and
damage to the equipment.
7 Install the instrument so
that the ON/OFF switch is
readily identifiable and
easily reached by the
operator.
• The ON/OFF switch is the system
disconnecting device. It disconnects
the mains circuit from the mains supply
before other parts of the instrument.
• Alternately, an externally installed
switch or circuit breaker (readily
identifiable and easily reached by the
operator) may be used as a
disconnection device.
