Power Supply and Measurement Safety
• Power Supply Safety
This instrument can output high currents and voltages. Make sure that the load or
device under test can safely handle the output current and voltage. Also, make sure
that the connection leads can safely withstand the expected currents and are
insulated for the expected voltages.
The instrument outputs may be connected so as to float relative to earth ground.
Isolation or floating voltage ratings are indicated on the instrument, near the
output terminal or the Circuit Common terminal.
• Voltage/Current Measurement Safety
Multimeters and other instruments capable of measuring high voltages and
currents are subject to specific safety concerns because of the circuits to which
they may be connected. To safely use these instruments, you need to understand
the markings on the instrument near the input terminals, which include the
Protection Limits and the IEC Measurement Category.
• Protection Limits
Agilent multimeters and other voltage measurement instruments provide
protection circuitry to prevent damage to the instrument and to protect against the
danger of electric shock, provided the Protection Limits are not exceeded. To
ensure safe operation of the instrument, do not exceed the Protection Limits
shown on the input terminals.
