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 nonhaz ardous 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 safet y prec autions required
to avoid possible injury. Read and fol l ow all installation, operation, and maintenance information carefully before using the
product. Refer to the user documentation for complete product specifications.
If the product is used in a manner not specified, the protection provided b y 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 specifications and operating li mits, and for ensuring that operat or s are adequately trained.
Operators use the product for its i ntended function. They must be trained in electrical safety procedures and proper use of the
instrument. They must be protected from electric shock and contact wit h hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, s etting 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, t hey should be performed only by servic e personnel.
Service personnel are trained to work on live circuits, perform saf e i ns tallations, and repair products . Only properly trained
service personnel may perform ins tallation and service procedures.
Keithley products are designed for us e with electrical signals that are measurement, control, and data I/O connections, with low
transient overvoltages, and mus t not be directly connected to mains voltage or to voltage sources with high transient
overvoltages. Measurement Category II (as referenced in IEC 60664) c onnections require protectio n for high transient
overvoltages often associated with local AC mains connections. Certain Keithley measuring instrument s may be connected to
mains. These instruments will be mar k ed as category II or higher.
Unless explicitly allowed in the spec i fications, 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
fixtures. The American National S tandards Institute (ANSI) states that a shock hazard exists when volta ge l evels 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 protec ted from electric shock at all tim es. The responsible body must ensure t hat operators
are prevented access and/or insulated from every connection point. In s ome cases, connections must be expose d to potential
human contact. Product operators i n these circumstances must be trained to protect themselves from the risk of el ec tric 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 direc tly 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 ca r ds, install protective
devices to limit fault current and v ol tage to the card.
Before operating an instrument, ensure that the line cord is connected t o a properly-grounded power receptacle. Inspect the
connecting cables, test leads, and j umpers for possible wear, cracks , or breaks before each use.
When installing equipment where ac cess to the main power cord is restric ted, 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 t he c i rcuit under
test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or di s connecting
cables or jumpers, installing or rem oving switching cards, or making i nternal 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 (e arth)
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 s pecified in the operating instructions, the protection provided by t he equipment may be
impaired.
Do not exceed the maximum signal lev els of the instruments and accessories. Maximum signal levels are defined in the
specifications and operating inf or mation and shown on the instrument panels, test fixture panels, and switching cards.
When fuses are used in a product, replac e with the same type and rating for continued protection against fire 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 fixture, keep the lid closed while power is applied to t he device under test. Safe operation requires the use
of a lid interlock.

Instrumentation and accessories s hall 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 — inclu ding the power
transformer, test leads, and input jacks — must be purchased from Keithley. S tandard 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 similarl y 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 applicabil i ty of a replacement
component, call a Keithley office for information.
Unless otherwise noted in product-specific 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
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 b ecomes contaminated and operation i s affected, the board
should be returned to the factor y for proper cleaning/servicing.
