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 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 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 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 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. 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 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 becomes contaminated and operation is affected, the board
should be returned to the factory for proper cleaning/servicing.

Product software and drivers
Go to the Product Support and Downloads web page (tek.com/product-support) to download drivers
and software for your instrument.
Available drivers and software include:
• KickStart Software: Enables quick test setup and data visualization when using one or
more instruments.
• Test Script Builder (TSB): This software provides an environment to develop a test program and
the ability to load the test program onto the instrument. Running a program loaded on the
instrument eliminates the need to send individual commands from the host computer to the
instrument when running a test.
• IVI-COM Driver: An IVI instrument driver you can use to create your own test applications in
C/C++, VB.NET, or C# programming languages. It can also be called from other languages that
support calling a DLL or ActiveX (COM) object. Refer to IVI Foundation (ivifoundation.org) for
additional information.
• LabVIEW
™
Software drivers: Drivers to communicate with National Instruments
LabVIEW Software.
• Keithley I/O layer: Manages the communications between Keithley instrument drivers and
software applications and the instrument itself. The I/O Layer handles differences in
communications required to support GPIB, serial, ethernet, and other communications buses so
that drivers and software applications do not need to handle the differences themselves.
To identify IP addresses of instruments that are connected to the local area network (LAN) and
support the VXI-11 discovery protocol, you can also use LXI Discovery Tool, available from the
Resources (lxistandard.org/Resources/Resources.aspx) page of the LXI Consortium website

Introduction
This section provides the information you need to install the 2600B, make communications
connections, and power up the instrument.
Cooling vents
The 2600B has side and top intake and rear exhaust vents. One side must be unobstructed to
dissipate heat.
Excessive heat could damage the 2600B and degrade its performance. Only operate the 2600B in an
environment where the ambient temperature does not exceed 50 °C.
Do not place a container of liquid (water or coffee, for instance) on the top cover. If it spills, the liquid
may enter the case through the vents and cause severe damage.
To prevent damaging heat build-up and ensure specified performance, use the
following guidelines.
The rear exhaust vent and either the top or both side intake vents must be unobstructed to
properly dissipate heat. Even partial blockage could impair proper cooling.
Do not position any devices adjacent to the 2600B that force air (heated or unheated) toward
its cooling vents or surfaces. This additional airflow could compromise accuracy.
When rack mounting the 2600B, make sure there is adequate airflow around both sides to
ensure proper cooling. Adequate airflow enables air temperatures within approximately one
inch of the 2600B surfaces to remain within specified limits under all operating conditions.
Section 2
Installation
Section 2: Installation Series 2600B System SourceMeter® instrument User's Manual
2-2 2600BS-900-01 Rev. A / August 2021
If high power dissipation equipment is rack mounted next to the 2600B, it could cause
excessive heating. To produce specified 2600B accuracies, maintain the specified ambient
temperature around the surfaces of the 2600B. In rack configurations with convection cooling
only, proper cooling practice places the hottest non-precision equipment (for example, the
power supply) at the top of the rack away from and above precision equipment (such as
the 2600B).
Mount precision equipment as low as possible in the rack, where temperatures are coolest.
You can add space panels above and below the 2600B to help provide adequate airflow.
Turning the instrument on and off
The 2600B operates from a line voltage of 100 V to 240 V at a frequency of 50 Hz or 60 Hz. Line
voltage is automatically sensed (there are no switches to set). Make sure the operating voltage in
your area is compatible.
Follow the procedure below to connect the 2600B to line power and turn on the instrument.
Operating the instrument on an incorrect line voltage may cause damage to the instrument,
possibly voiding the warranty.
To turn a 2600B on and off:
1. Before plugging in the power cord, make sure that the front-panel POWER switch is in the
off (O) position.
2. Connect the female end of the supplied power cord to the ac receptacle on the rear panel.
3. Connect the other end of the power cord to a grounded ac outlet.
The power cord supplied with the 2600B contains a separate protective earth (safety ground)
wire for use with grounded outlets. When proper connections are made, the instrument
chassis is connected to power-line ground through the ground wire in the power cord. In
addition, a chassis ground connection is provided through a screw on the rear panel. This
terminal should be connected to a known protective earth. In the event of a failure, not using
a properly grounded protective earth and grounded outlet may result in personal injury or
death due to electric shock.
Do not replace detachable mains supply cords with inadequately rated cords. Failure to use
properly rated cords may result in personal injury or death due to electric shock.
Series 2600B System SourceMeter® instrument User's Manual Section 2: Installation
2600BS-900-01 Rev. A / August 2021 2-3
Hazardous voltages may be present in the test system. To prevent injury or death, remove
power from the instrument or test system and discharge any energy storage components (for
example, capacitors or cables) before changing any connections that might allow contact
with an uninsulated conductor.
On some sensitive or easily damaged devices under test (DUTs), the instrument power-up and
power-down sequence can apply transient signals to the DUT that may affect or damage it. When
testing this type of DUT, do not make final connections to it until the instrument has completed its
power-up sequence and is in a known operating state. When testing this type of DUT, disconnect it
from the instrument before turning the instrument off.
To prevent any human contact with a live conductor, connections to the DUT must be fully insulated
and the final connections to the DUT must only use safety-rated safety-jack-socket connectors that
do not allow bodily contact.
4. To turn your instrument on, press the front-panel POWER switch to place it in the on (I) position.
5. To turn your instrument off, press the front-panel POWER switch to place it in the off (O) position.
Placing a 2600B in standby
Hazardous voltages may be present on all output and guard terminals. To prevent electrical
shock that could cause injury or death, never make or break connections to the 2600B while
the instrument is powered on. Turn off the equipment from the front panel or disconnect the
main power cord from the rear of the 2600B before handling cables. Putting the equipment
into standby does not guarantee that the outputs are powered off if a hardware or software
fault occurs.
When the instrument is on, the output may be placed in an active output state (output on) or a
standby mode (output off). From the front panel, pressing the OUTPUT ON/OFF control toggles the
output using the present instrument configuration. You can also place the output in standby over the
remote interface by sending the following command:
smuX.source.output = smuX.OUTPUT_OFF
Even though the instrument is placed in standby, the output may not actually be off.
Warmup period
The 2600B must be turned on and allowed to warm up for at least two hours to achieve
rated accuracies.
Section 2: Installation Series 2600B System SourceMeter® instrument User's Manual
2-4 2600BS-900-01 Rev. A / August 2021
Line frequency configuration
The factory configures the 2600B to detect the power line frequency automatically at each power-up.
This detected line frequency (either 50 Hz or 60 Hz) is used for aperture (NPLC) calculations.
In noisy environments, you can manually configure the instrument to match the actual line frequency.
To configure the line frequency from the front panel:
1. Press the MENU key, then turn the navigation wheel to select LINE-FREQ, and then press the
ENTER key.
2. Turn the navigation wheel to select the appropriate frequency and then press the ENTER key. To
configure the instrument to automatically detect line frequency at each power-up, select AUTO.
3. Press the EXIT (LOCAL) key to return to the main display.
To configure the line frequency from a remote interface:
Set the localnode.linefreq or the localnode.autolinefreq attribute. To set the line
frequency to 60 Hz, send:
localnode.linefreq = 60
To configure the instrument to automatically detect line frequency at each power-up:
localnode.autolinefreq = true
