Important test system safety information
This system contains instruments that can produce hazardous
voltages. It is the responsibility of the test system installer,
maintenance personnel, and service personnel to make sure the
system is safe during use and is operating properly. You must also
realize that in many test systems a single fault, such as a software
error, may output hazardous signal levels even when the system
indicates that there is no hazard present. It is important that you
consider the following factors in your system design and use:
 The international safety standard IEC 61010-1 defines voltages as
hazardous if they exceed 30 V RMS and 42.4 V peak, or 60 V DC
for equipment rated for dry locations. Keithley Instruments, Inc.
products are only rated for dry locations.
 Read and comply with the specifications of all instruments in the
system. The overall allowed signal levels may be constrained by
the lowest rated instrument in the system. For example, if you are
using a 500 V power supply with a 300 V DC rated switch, the
maximum allowed voltage in the system is 300 V DC.
 Make sure any test fixture connected to the system protects the
operator from contact with hazardous voltages, hot surfaces, and
sharp objects. Use shields, barriers, insulation, and safety
interlocks to accomplish this.
 Cover the device under test (DUT) to protect the operator from
flying debris in the event of a system or DUT failure.
 Double-insulate all electrical connections that an operator can
touch. Double insulation ensures the operator is still protected
even if one insulation layer fails. Refer to IEC 61010-1 for
specific requirements.
