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.

Current Readback Range: The Model 2306 has two ranges for current readback: 5A and
5mA. On the 5A range display resolution is 100μA, and on the 5mA range resolution is 0.1μA.
The power supply also has a digital voltmeter (DVM) that is independent of the power supply
circuit. The DVM can measure up to +30V (1mV resolution).
When used with a pulsed load, the power supply can read back peak current, idle current, and
average current. See Section 3 for details. A long integration (up to 60 seconds) function is
provided to measure average current of a low frequency pulse (long period) or a series of pulses.

If mounting the power supply in a location where the display cannot be seen or the controls
are not easily accessible, use the optional Model 2304-DISP or 2306-DISP Display Module (see
Figure 1-4). This remote display module includes all front panel instrument controls/features
(with the exception of power). All features/menus work as described for the Model 2306
(exceptions are noted). A 9 foot cable attaches the remote display to the rear of the power supply
allowing the unit to be operated remotely.

When the remote display module is unplugged, control returns to the main display module.
NOTE When connecting or disconnecting the remote display, allow a few seconds for the
power supply to recognize the action. Fast, repeated connects/disconnects of the
remote display may cause the power supply to hang or appear to hang. Disconnecting
the remote display and waiting a few seconds to reconnect it may clear the problem.
If not, cycling power on the power supply clears the condition.
1-8 Getting Started
Power-up
Line power connection
The power supply operates from a line voltage in the range of 100-120VAC/200-240VAC at
a frequency of 50 or 60Hz. Line voltage and frequency are automatically sensed, therefore there
are no switches to set. Check to see that the line power in your area is compatible. Use the
:SYSTem :LFRequency? query (Section 11) to read the line frequency.
Perform the following steps to connect the power supply to the line power and turn it on:
WAR NING The power cord su
use with grounded outlets. When proper connections are made, instrument
chassis is connected to power line ground through the ground wire in the power
cord. Failure to use a grounded outlet may result in personal injury or death due
to electric shock.
1. Before plugging in the power cord, make sure the front panel power switch is in the off
(0) positio
2. Connect the female end of the supplied power cord to the AC receptacle on the rear
panel.
3. T
urn on the power supply by pressing the front panel power switch to the on (1) position.
NOTE
NOTE
On some sensitive or easily damaged devices under test (DUTs), the instrument
power-up 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.
On some sensitive or easily damaged devices under test (DUTs), the instrument
power-down sequence can apply transient signals to the DUT that may affect or
damage it. When testing this type of DUT, disconnect it from the instrument
before turning the instrument off.
Power-up sequence
pplied with the Model 2306 contains a separate ground for
n.
On power-up, the power supply performs self-tests on its RAM and EPROM. After a blinking
cursor appears on line one, RAM tests are completed. After a blinking cursor appears on line
two, EPROM self tests are completed.
NOTE If a problem develops while the instrument is under warranty, return it to
Keithley Instruments, for repair.
If the instrument passes the self tests, the following information is briefly displayed:
• Top line — The model number and the IEEE-488 address are displayed. (The factory
defa
ult GPIB address is 16.)
• Bottom line — Firmware revision levels are displayed for the main board and the display
board. Also displayed is the detected line frequency.
After displaying the above information, any errors that occurred during the startup sequence
will be displayed. Then, the instrument goes to the default settings or the saved power up settings
(*RST or SAV0-4) display type with the output off (see “Default settings” on page 1-11). Any
missed error messages may be viewed over the bus using the :SYST:ERR? (see “Error Queue”
in Section 7).
NOTE For Models 2306-PJ and 2306-VS, the saved power up settings available are from
SAV0-SAV2.
Fuse replacement
A rear panel fuse protects the power line input of the power supply. If the line fuse needs to
be replaced, perform the following steps:
1. Power off the unit and remove line cord.
2. The fuse drawer is located on the left side of the AC receptacle (see Figure 1-5). On the
right side of the fuse drawer is a small tab. At this location, use a thin-bladed knife or
screwdriver to pry the fuse drawer open.
3. Slide the fuse drawer out to gain access to the fuse. Note that the fuse drawer does not
pull all the way out of the power module.
4. Snap the fuse out of the drawer and replace it with the same type (250V, 2.0A, 5 × 20mm
time lag). The Keithley part number is FU-81.
