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 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

specifications.

If the product is used in a manner not specified, 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 specifications 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 Instruments measuring instruments may be connected to mains. These

instruments will be marked as category II or higher.

Unless explicitly allowed in the specifications, 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 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.

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 specified 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

defined in the specifications and operating information and shown on the instrument panels, test fixture

panels, and switching cards.

When fuses are used in a product, replace 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 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 hazard. 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 warning, 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.

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.

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 very 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 fire, 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 office for information.

Unless otherwise noted in product-specific literature, Keithley Instruments 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 becomes contaminated and operation is affected, the board should be returned to the factory for

proper cleaning/servicing.
