Safety Precautions
The following safety precautions should be observed
before using this product and any associated instrumenta-
tion. Although some instruments and accessories would
normally be used with non-hazardous voltages, there are
situations where hazardous conditions may be present.
This product is intended for use by qualified personnel
who recognize shock hazards and are familiar with the
safety precautions required to avoid possible injury. Read
the operating information carefully before using the
product.
The types of product users are:
Responsible body is the individual or group responsible for
the use and maintenance of equipment, for ensuring that
the equipment is operated within its specifications and
operating limits, and for ensuring that operators are ade-
quately 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. Other-
wise, 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.
Exercise extreme caution when a shock hazard is present.
Lethal voltage may be present on cable connector jacks or
test fixtures. The American National Standards Institute
(ANSI) states that a shock hazard exists when voltage levels

2
greater than 30V RMS, 42.4V peak, or 60VDC are present.
A good safety practice is to expect that hazardous voltage
is present in any unknown circuit before measuring.
Users of this product must be protected from electric shock
at all times. The responsible body must ensure that users
are prevented access and/or insulated from every connec-
tion point. In some cases, connections must be exposed to
potential human contact. Product users in these circum-
stances must be trained to protect themselves from the risk
of electric shock. If the circuit is capable of operating at or
above 1000 volts,
no conductive part of the circuit may be
exposed.
As described in the International Electrotechnical Commis-
sion (IEC) Standard IEC 664, digital multimeter measuring
circuits (e.g., Keithley Models 175A, 199, 2000, 2001,
2002, and 2010) are Installation Category II. All other
instruments’ signal terminals are Installation Category I and
must not be connected to mains.
Do not connect switching cards directly to unlimited
power circuits. They are intended to be used with imped-
ance limited sources. NEVER connect switching cards
directly to AC mains. When connecting sources to switch-
ing cards, install protective devices to limit fault current
and voltage to the card.
Before operating an instrument, make sure the line cord is
connected to a properly grounded power receptacle.
Inspect the connecting cables, test leads, and jumpers for
possible wear, cracks, or breaks before each use.
For maximum safety, do not touch the product, test cables,
or any other instruments while power is applied to the cir-
cuit under test. ALWAYS remove power from the entire test
system and discharge any capacitors before: connecting or
disconnecting cables or jumpers, installing or removing
switching cards, or making internal changes, such as
installing or removing jumpers.

Do not touch any object that could provide a current path
to the common side of the circuit under test or power line
(earth) ground. Always make measurements with dry hands
while standing on a dry, insulated surface capable of with-
standing the voltage being measured.
The instrument and accessories must be used in accor-
dance with its specifications and operating instructions or
the safety of the equipment may be impaired.
Do not exceed the maximum signal levels of the instru-
ments and accessories, as defined in the specifications and
operating information, and as shown on the instrument or
test fixture panels, or switching card.
When fuses are used in a product, replace with same type
and rating for continued protection against fire hazard.
Chassis connections must only be used as shield connec-
tions for measuring circuits, NOT as safety earth ground
connections.
If you are using a test fixture, keep the lid closed while
power is applied to the device under test. Safe operation
requires the use of a lid interlock.
If a screw 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.
Instrumentation and accessories shall not be connected to
humans.
Before performing any maintenance, disconnect the line
cord and all test cables.
To maintain protection from electric shock and fire,
replacement components in mains circuits, including the
power transformer, test leads, and input jacks, must be pur-
chased from Keithley Instruments. Standard fuses, with
applicable national safety approvals, may be used if the rat-
ing and type are the same. Other components that are not
safety related may be purchased from other suppliers as
long as they are equivalent to the original component.
(Note that selected parts should be purchased only through
Keithley Instruments to maintain accuracy and functional-
ity of the product.) If you are unsure about the applicability
of a replacement component, call a Keithley Instruments
office for information.
To clean an instrument, use a damp cloth or mild, water
based cleaner. Clean the exterior of the instrument only.
Do not apply cleaner directly to the instrument or allow
liquids to enter or spill on the instrument. Products that
consist of a circuit board with no case or chassis (e.g., data
acquisition board for installation into a computer) should
never require cleaning if handled according to instructions.
If the board becomes contaminated and operation is
affected, the board should be returned to the factory for
proper cleaning/servicing.
