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 non-hazardous voltages, there are situations where hazardous
conditions may be present.

This product is intended for use by qualified 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 manual for complete product specifications.

If the product is used in a manner not specified, the protection provided by the product may be impaired.

if the operator may perform them. Otherwise, they should be performed only by service personnel.

Service personnel

trained service personnel may perform installation and service procedures.

Keithley products are designed for use with electrical signals that are rated Measurement Category I and Measurement Category
II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most measurement, control, and
data I/O signals are Measurement Category I and must not be directly connected to mains voltage or to voltage sources with
high transient over-voltages. Measurement Category II connections require protection for high transient over-voltages often
associated with local AC mains connections. Assume all measurement, control, and data I/O connections are for connection to
Category I sources unless otherwise marked or described in the Manual.

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 30V RMS,

42.4V peak, or 60VDC are present.

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 volts,

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, make sure 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.

The instrument and accessories must be used in accordance with its specifications and operating instructions or the safety of the
equipment may be impaired.

Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and operating
information, and as shown on the instrument or test fixture panels, or switching card.

When fuses are used in a product, replace with same type and rating for continued protection against fire hazard.

Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth 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 safety earth ground using the wire recommended in the user documentation.

The symbol on an instrument indicates that the user should refer to the operating instructions located in the manual.

The symbol on an instrument shows that it can source or measure 1000 volts or more, including the combined effect of
normal and common mode voltages. Use standard safety precautions to avoid personal contact with these voltages.

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. 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.

To clean an instrument, use a damp cloth 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., 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.

Quick Results Guide

NOTE

This quick results guide provides information on five different models of battery or
battery/charger simulators (Models 2302, 2302-PJ, 2306, 2306-PJ, and 2306-VS).
In this guide, references to Model 2306 apply to all of the simulators unless
otherwise noted. Likewise, references to specific models (for example, Model 2306,
2306-PJ, or 2306-VS, or Model 2302 or 2302-PJ) refer only to the models listed.
Since the Model 2302 and 2302-PJ are single channel battery simulators, functions
related to the second channel (i.e., the charger channel) are not available for these
models. Therefore:

• battery and charger channel features contained in this manual apply for
the Models 2306, 2306-PJ, and 2306-VS

• only battery channel features contained in this manual apply for the
Models 2302 and 2302-PJ

References to the Model 2302 also apply to the Model 2302-PJ unless otherwise
noted. Refer to Appendix F of Instruction Manual (2306-901-01) for specific
Model 2302 and 2302-PJ information.

Information contained in this guide applies to all power supply channels (unless
otherwise noted). In this manual, channel 1 refers to the battery channel while
channel 2 refers to the charger channel (2306, 2306-PJ, and 2306-VS features only).

For additional information on any feature discussed in this guide (including
programming examples), refer to the Instruction Manual (part number
2306-901-00).

2 Introduction

Introduction

This guide is designed to familiarize users of the Keithley Model 2306 Dual Channel Battery/
Charger Simulator and Model 2302 Single Channel Battery Simulator with the basic operating
features available from the instrument’s front panel and also the GPIB bus. The sequence of
operating instructions reflects the order in which the instrument would be configured for a
typical application. For each operating mode, an example set of bus commands is provided.
While the SCPI command strings are generic, the exact programming syntax will depend on the
test program language.

Performance features

The battery channel, the single output channel of the Model 2302 and channel #1 on the

Model 2306, has several enhanced performance features:

1. The transient response, defined by the voltage recovery time and voltage drop when
subjected to a 1000% load change, is faster. For exact specifications, refer to Appendix A
in the Model 2306 Instruction Manual.

2. Three current trigger ranges for pulsed current and long integration operation as opposed
to a single range on the charger channel, channel #2 (5A). Available trigger ranges for the
5A current range: 100mA, 1A, and 5A. Available trigger ranges for the 500mA current
range (Model 2306-PJ and 2302-PJ): 10mA, 100mA, and 500mA.

3. Variable output impedance on channel #1 (0

WARNING

When installing a unit into a test system, make sure the external power
sources do not apply voltage to the power supply in excess of its maximum
limits (see specifications). Failure to do so could result in personal injury or
death.

WARNING

The power cord supplied with the Model 2306 contains a separate ground
for 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.

Figure 2 shows a rear panel view of the Models 2306 and 2306-PJ detailing the connector

sockets for the battery channel “OUTPUT #1” and the charger channel “OUTPUT #2.” Figure 3
shows the rear panel of the Model 2306-VS. The Model 2306 does not have an internal local
sense connection. Therefore, the operator must connect the DUT to the supply in either a remote
or local sense configuration as illustrated. For a 4-wire remote sense application, the sense inputs
to the supply must be connected at load as close to the inputs of the load as possible through
twisted pair leads as shown in Figure 4.
