Important test system safety information
This product is sold as a stand-alone instrument that may become
part of a system that could contain hazardous voltages and energy
sources. It is the responsibility of the test system designer, integrator,
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:
ƒ
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.
ƒ 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 only 300 V DC.
ƒ Make sure any test fixture connected to the system protects
the operator from contact with hazardous voltages, hot
surfaces, or sharp objects. This may be accomplished by
using shields, barriers, insulation, safety interlocks, and so
on
ƒ Cover the device under test (DUT) to protect an operator
from flying debris in the event of a system or DUT failure.
ƒ
Double insulate all electrical connections that an operator
can touch. Double insulation ensures the operator is still
