Introduction
Safety precautions
The following safety precautions should be observed before using this product and any
associated instrumentation. Although some instruments and accessories would normally
be used with nonhazardous voltages, there are situations where hazardous conditions may
be present.
This product is intended for use by qualied personnel who recognize shock hazards and
are familiar with the safety precautions required to avoid possible injury. Read and follow
all installation, operation, and maintenance information carefully before using the product.
Refer to the user documentation for complete product specications.
If the product is used in a manner not specied, the protection provided by the product
warranty may be impaired.
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 specications and
operating limits, and for ensuring that operators 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
properly, for example, setting the line voltage or replacing consumable materials.
Maintenance procedures are described in the user documentation. 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, perform safe installations, and repair
products. Only properly trained service personnel may perform installation and service
procedures.
Keithley Instruments products are designed for use with electrical signals that are
measurement, control, and data I/O connections, with low transient overvoltages, and
must not be directly connected to mains voltage or to voltage sources with high transient
overvoltages. Measurement Category II (as referenced in IEC 60664) connections require
protection for high transient overvoltages often associated with local AC mains connections.
Certain Keithley measuring instruments may be connected to mains. These instruments will be
marked as category II or higher.
Unless explicitly allowed in the specications, operating manual, and instrument labels, do not
connect any instrument to mains.
Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on
cable connector jacks or test xtures. The American National Standards Institute (ANSI) states
that a shock hazard exists when voltage levels greater than 30 V
RMS, 42.4 V peak, or
60 VDC are present. A good safety practice is to expect that hazardous voltage is present in
any unknown circuit before measuring.
Operators of this product must be protected from electric shock at all times. The responsible
body must ensure that operators are prevented access and/or insulated from every connection
point. In some cases, connections must be exposed to potential human contact. Product
operators in these circumstances must be trained to protect themselves from the risk of electric
shock. If the circuit is capable of operating at or above 1000 V, no conductive part of the circuit
may be exposed.
Do not connect switching cards directly to unlimited power circuits. They are intended to be
used with impedance-limited sources. NEVER connect switching cards directly to AC mains.
When connecting sources to switching cards, install protective devices to limit fault current and
voltage to the card.
Before operating an instrument, ensure that 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.
When installing equipment where access to the main power cord is restricted, such as rack
mounting, a separate main input power disconnect device must be provided in close proximity
to the equipment and within easy reach of the operator.
For maximum safety, do not touch the product, test cables, or any other instruments while
power is applied to the circuit 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.
Safety
Introduction
The WARNING heading in the user documentation 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 the user documentation 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 re, replacement components in mains
circuits — including the power transformer, test leads, and input jacks — must be
purchased from Keithley Instruments. Standard fuses with applicable national safety
approvals may be used if the rating and type are the same. The detachable mains
power cord provided with the instrument may only be replaced with a similarly rated
power cord. 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 functionality of the product). If you are unsure about the applicability of
a replacement component, call a Keithley Instruments ofce for information.
Unless otherwise noted in product-specic literature, Keithley instruments are
designed to operate indoors only, in the following environment: Altitude at or below
2,000 m (6,562 ft); temperature 0 °C to 50 °C (32 °F to 122 °F) ; and pollution
degree 1 or 2.
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., a 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.
Safety precaution revision as of March 2016.
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 withstanding the voltage being measured.
When fuses are used in a product, replace with the same type and rating for continued
protection against re hazard.
For safety, instruments and accessories must be used in accordance with the operating
instructions. If the instruments or accessories are used in a manner not specied in the
operating instructions, the protection provided by the equipment may be impaired.
Do not exceed the maximum signal levels of the instruments and accessories. Maximum
signal levels are dened in the specications and operating information and shown on the
instrument panels, test xture panels, and switching cards.
Chassis connections must only be used as shield connections for measuring circuits, NOT
as protective earth (safety ground) connections.
If you are using a test xture, 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 protective earth (safety ground) using the wire
recommended in the user documentation.
The symbol on an instrument means caution, risk of danger. The user must refer to the
operating instructions located in the user documentation in all cases where the symbol
is marked on the instrument.
The symbol on an instrument means caution, risk of electric shock. Use standard
safety precautions to avoid personal contact with these voltages.
The symbol on an instrument shows that the surface may be hot. Avoid personal
contact to prevent burns.
The symbol indicates a connection terminal to the equipment frame.
If this symbol is on a product, it indicates that mercury is present in the display lamp.
Please note that the lamp must be properly disposed of according to federal, state, and local
laws.
