Safety precautions
The following safety precautions should be obser ved before using this product and any
associated instrumentation. A lthough 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 personnel who recognize shock hazards and are familiar
with the safety precautions required to avoid possible injur y. 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 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 acc ess 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 c ards directly to unlimited power circuits. They are intended to be
used with impedanc e-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.
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.
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 instr uctions, 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.
When fuses are used in a product, replace with the same t ype and rating for continued
protection against re hazard.
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 warning, risk of electric shock. Use standard safety
precautions to avoid personal contact with these voltages.
The symbol indicates a connection terminal to the equipment frame.
The symbol on an instrument means caution, risk of hazard. The user must refer to the
operating instr uctions located in the user documentation in all cases where the symbol is
marked on the instrument.
The symbol on an instrument shows that the surface may be hot. Avoid personal c ontact to
prevent burns.
If this symbol is on a product, it indicates that mercur y is present in the display lamp. Please
note that the lamp must be properly disposed of according to federal, state, and local laws.
The WARNING heading in the user documentation explains hazards 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.
The CAUTION heading with the symbol in the user documentation explains hazards that
could result in moderate or minor injury or damage the instrument. Always read the associated
information ver y carefully before performing the indicated procedure. Damage to the instrument
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. 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 to maintain accuracy
and functionality of the product). If you are unsure about the applicability of a replacement
component, call a Keithley oce 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 cloth dampened with deionized water or mild, water-based
cleaner. Clean the exterior of the instr ument 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 aected, the board should be returned to the factory for proper cleaning/ser vicing.
Safety precaution revision as of June 2017.
Carefully consider and congure the appropriate outputo state, source levels, and compliance levels before
connecting the instrument to a device that can deliver
energy. Failure to consider the output-o state, source
levels, and compliance levels may result in damage to the
instrument or to the device under test.
