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 prec autions 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 specificat ions.
If the product is used in a manner not specified, the protection provided by the pr oduct 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 t hat the
equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.
Operators use the product for its i ntended function. They must be traine d 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, 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, they should be performed only by service personnel.
Service personnel are trained to work on live circuits, perform saf e installations, and repair products . Only properly trained
service personnel may perform ins tallation and service procedures.
Keithley products are designed f or use with electrical signals that are m easurement, control, and data I/O connections, with low
transient overvoltages, and mus t not be directly connected to mains v oltage or to voltage sources with high transient
overvoltages. Measurement Cat egory II (as referenced in IEC 60664) c onnections 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 mar k ed as category II or higher.
Unless explicitly allowed in the spec i fications, operating manual, an d 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) stat es 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 v oltage is present in any
unknown circuit before measuring.
Operators of this product must be protec ted 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 i n these circumstances must be trained t o 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 direc tly to unlimited power circuits. T hey are intended to be used with impedance-limited
sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching car 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 to 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 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 c ircuit under
test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting
cables or jumpers, installing or rem oving 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, insul ated surface capable of withstandi ng the
voltage being measured.
For safety, instruments and accessories must be used in accordance with the operating instructions. If the ins truments or
accessories are used in a manner not s pecified in the operating instructi ons, the protection provided by the eq uipment may be
impaired.
Do not exceed the maximum signal lev els of the instruments and accessori es. 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 contin ued protection against fire hazard.
Chassis connections must only be used as shield connections for measuring circuits, NOT as protective ear th (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 prot ective 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 t o the operating instructions located in t he
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 sur face may be hot. Avoid personal cont ac t to prevent burns.
The symbol indicates a connection termin al to the equipment frame.
If this symbol i s 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 hazards that might result in personal inj ury or death. Always read
the associated information very car efully 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 exp lains hazards that could result in moderate or minor
injury or damage the instrument. Always read the associated information v ery carefully before performing t he 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 c ables.
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. 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 instrum ent 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 equival ent to the original component (note that selected parts should be purchase d only through
Keithley to maintain accuracy and f unctionality of the product). If you are unsure about the applicability of a replacement
component, call a Keithley office for information.
Unless otherwise noted in product-specific literature, Keithle y 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 degr ee 1 or 2.
To clean an instrument, use a cloth dampened with deionized water or mild, water-based cleaner. Clean the e xterior 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 acc or ding to instructions. If the board becomes contaminated and operation is affected, the board
should be returned to the factor y for proper cleaning/servicing.

Remote communications interfaces
Section 3
You can choose from one of several communication i nterfaces to send commands to and receive
responses from the 2470.
You can control the 2470 from only one communications interface at a time. The first interface on
which the instrument receives a message takes co ntrol of the instrument. If another interface sends a
message, that interface can take control of t he inst rument. You may need to enter a password to
change the interface, depending on the setting of interface access.
The 2470 automatically detects the type of communications interface (LAN, USB, or GPIB) when you
connect to the respective port on the rear panel of t he inst rument. In most cases, you do not need to
configure anything on the instrument. In addit ion, you do not need to reboot if you change the type of
interface that is connected.
Supported remote interfaces
The 2470 supports the following remote interfaces:
• GPIB: IEEE-488 instrumentation general purpose interface bus
• Ethernet: Local-area-network communications
• USB: Type B USB port
• TSP-Link: A high-speed trigger synchronization and communi cat ions bus that test system
builders can use to connect multiple instruments in a master-and-subordinate configuration
For details about TSP-Link, see “TSP-Link System E xpansion Interface” in the Model 2470
Reference Manual.

GPIB communications
The 2470 GPIB interface is IEEE Std 488.1 compliant and supports IEEE Std 488.2 common
commands and status model topology.
You can have up to 15 devices connected to a GPIB interface, including the controller. The maximum
cable length is the lesser of either:
• The number of devices multiplied by 2 m (6.5 ft)
• 20 m (65.6 ft)
You may see erratic bus operation if you ignore these limits.
Install the GPIB driver software
Check the documentation for your GPIB controller for information about where to acquire drivers.
Keithley Instruments also recommends that you check the website of the GPIB controller for the latest
version of drivers or software.
It is important that you install the drivers before you connect the hardware. This prevents associating
the incorrect driver to the hardware.
Install the GPIB cards in your computer
Refer to the documentation from the GPIB controller vendor for information about installing the GPI B
controllers.
Connect GPIB cables to your instrument
To connect a 2470 to the GPIB interface, use a cable equipped with standard GPIB connectors, as
shown below.

Model 2470
Using a remote interface
High Voltage SourceMeter Instrument User's Manual Section 3:
To allow many parallel connections to one instrument, stack the connectors. Each connector has two
screws on it to ensure that connections remain secure. The figure below shows a typical connection
diagram for a test system with multiple instruments.
To avoid possible mechanical damage, stac k no more than three connectors on any one
instrument. To minimize interference caused by electromagnetic radiation, use only shielded
GPIB cables. Contact Keithley Instrumen ts for shielded cables.
Figure 12: IEEE-488 connection example
To connect the GPIB cable to the instrument:
1. Align the cable connector with the connector on the 2470 rear panel.
2. Attach the connector. Tighten the screws securely but do not overtighten them.
3. Connect any additional connectors from other in st ruments, as required for your application.
4. Make sure that the end of the cable is properly con nected to the controller.

Set the GPIB address
The default GPIB address is 18. You can set the add ress from 1 to 30 if it is unique in the system.
This address cannot conflict with an addres s t hat is assigned to another instrument or to the GPIB
controller.
GPIB controllers are usually set to 0 or 21. To be safe, do not configure any instrument to have an
address of 21.
The instrument saves the address in nonvolatile memory. It does not change when you send a reset
command or when you turn the power off and on agai n.
To set the GPIB address from the front panel:
1. Press the MENU key.
2. Select Communication.
3. Select the GPIB tab.
4. Set the GPIB Address.
5. Select OK.
You can also set the GPIB address using remote com m ands. Set the GPIB address with the SCPI
command :SYSTem:GPIB:ADDRess or the TSP command gpib.address.
LAN communications
You can communicate with the instrument using a lo cal area network (LAN).
When you connect using a LAN, you can use a web bro wser to access the internal web page of the
instrument and change some of the instrument set t i ngs. For more information, see
interface (on page 3-12).
The 2470 is a version 1.5 LXI Device Specificati on 2016 instrument that supports TCP/IP and
complies with IEEE Std 802.3 (ethernet LAN). There is one LAN port (located on the rear panel of the
instrument) that supports full connectivity on a 10 M bps or 100 Mbps network. The 2470 automatically
detects the speed.
Using the web
The 2470 also supports Multicast DNS (mDNS) and DNS Service Discovery (DNS-SD), which are
useful on a LAN with no central administration.
