General definitions
The types of product users are:
Responsible body is the individual or group responsible for the use and maintenance of equipment, and for ensuring that oper-
ators are adequately trained.
Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the
instrument. They must be protected from electric shock and contact with hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it operating, for example, setting the line voltage
or replacing consumable materials. Maintenance procedures are described in the manual. The procedures explicitly state if the
operator may perform them. Otherwise, they should be performed only by service personnel.
Service personnel are trained to work on live circuits, and perform safe installations and repairs of products. Only properly
trained service personnel may perform installation and service procedures.
If
or
is present, connect it to safety earth ground using the wire recommended in the user documentation.
!
The
symbol on an instrument indicates that the user should refer to the operating instructions located in the manual.
The
symbol on an instrument shows that it can source or measure 1000 volts or more, including the combined effect of
normal and common mode voltages. Use standard safety precautions to avoid personal contact with these voltages.
The WARNING heading in a manual explains dangers that might result in personal injury or death. Always read the associated
information very carefully before performing the indicated procedure.
The CAUTION heading in a manual explains hazards that could damage the instrument. Such damage may invalidate the
warranty.
Operation and use
WARNING
There can be hazardous voltages exposed in this test fixture and risk of electric shock.
Do not touch internal electrical connections. Remove all sources of power before open-
ing cover and changing devices.
If this test fixture is used with an instrument capable of sourcing voltages greater than
42V, then the user must provide an additional safety barrier to prevent the possibility of
electrical shock.
No interlock features are provided by this device—properly make all connections and
close the lid before energizing instrumentation connected to this test fixture.
CAUTION
The current leakage specifications depend upon a clean fixture. Avoid contamination
that could cause degraded performance and increase current leakages beyond specified
limits.
NOTE
It is safe to use the test fixture without an additional safety barrier if the connected instrument has
a Safety Interlock that can disable any high voltage ranges capable of sourcing greater than 42V,
such as the Keithley Model 4200.
