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 us-
ing 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.
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 equip-
ment 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 manual. 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, and perform safe installations and repairs of products. Only properly
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 as-
sociated 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. 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 volts, 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 sourc-
es. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective de-
vices 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 con-
necting 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 pow-
er 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 ca-

bles 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. Al-
ways 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 in-
formation, 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.
The symbol indicates a connection terminal to the equipment frame.
The WA R N I NG heading in a manual 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 a manual explains hazards that could damage the instrument. Such damage may invalidate the war-
ranty.
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 ap-
provals, 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 accord-
ing to instructions. If the board becomes contaminated and operation is affected, the board should be returned to the factory for
proper cleaning/servicing.

Quick Start Guide Integra Series 3
Getting started
Introduction
This Quick Start Guide is intended to get a new user familiar with the operation of
the instrument. It summarizes operation for all basic measurement functions and
most features of the Integra instruments. It also summarizes the operation of the
Model 7700 switching module, which adds switching and scanning capabilities to
an Integra measurement system.
Topics that are not discussed in this guide include the following: Setups (saving
and restoring), details on triggering, dry circuit ohms (Model 2750), limits and dig-
ital I/O, multiple channel operation and advanced scanning.
NOTE In this guide, the term “Model 27xx” refers to all three Integra instru-
ments (Models 2700, 2701, and 2750).
Reference Details on all Model 27xx operations are provided in the Model 27xx
User’s Manual. This includes important additional information on topics
covered in the guide, and full details on topics not covered in this guide.
Details on the Model 7700 switching module is covered in the Model
27xx User’s Manual. Details on Model 7700 installation and connections
are provided in the User’s Guide supplied with the switching module.
Details on other Keithley switching modules are covered in the supplied
User’s Guide.
WARNING Exercise extreme caution when a shock hazard is present.
Lethal voltage may be present on cable connections or test fix-
tures. 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. A good safety practice
is to expect that hazardous voltage is present in any unknown
circuit before measuring.
While learning to operate an Integra system, it is strongly rec-
ommended that only non-lethal signal levels be connected to
the front panel or switching module inputs.
Measure and switching capabilities
The basic measurement capabilities of an Integra system are summarized in Figure 1.
TopicsTopics Topics

4 Integra Series Quick Start Guide
CAUTION The maximum input for the mainframe is 1000V peak. However,
if a measure switch module (e.g., module 7700) is installed, the
maximum allowable input voltage for the system (including the
mainframe) is degraded to the maximum voltage rating of the
card. The maximum signal levels for the Model 7700 switching
module are listed in Table 2 on page 35.
Figure 1
Integra measurement capabilities
Model 7700 switching module capabilities
The Model 7700 has 20 input channels (1 through 20) for all Integra measure-
ments, except amps. For 2-wire measurements, any of these 20 2-pole input
channels can be connected (via relay switches) to the DMM of the mainframe. For
4-wire measurements (e.g., Ω4), the channels are paired. Input channels 1
through 10 are paired to sense channels 11 through 20. When an input channel
(e.g., 1) is closed, the paired sense channel (e.g., 11) also closes to connect the
4-wire input to the input and sense terminals of the DMM.
For amps measurements, two dedicated channels (22 and 23) are provided to
measure current. For temperature measurements, the switching module has a
built-in cold (reference) junction that allows thermocouples to be connected
directly to the screw terminals (channels 1 through 20) of the module.

Power-up
NOTE For the following power-up procedure, refer to Figure 2 (Model
2700), Figure 3 (Model 2701), or Figure 4 (Model 2750).
1. Check to see that the line voltage indicated in the window of the fuse holder
assembly is correct for the operating voltage in your area. If not, refer to
Section 1 of the Model 27xx User’s Manual (see “Setting line voltage and
replacing fuse”).
CAUTION Operating the instrument on an incorrect line voltage may
cause damage to the instrument, possibly voiding the warranty.
2. Before plugging in the power cord, make sure the front panel power switch
is in the off (O) position.
3. Connect the female end of the supplied power cord to the AC receptacle on
the rear panel. Connect the other end of the power cord to a grounded AC
outlet.
WARNING The power cord supplied with the mainframe contains a sepa-
rate ground wire 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.
4. Turn on the instrument by pressing the front panel power switch to the on (I)
position. After going through its power-up sequence, the instrument begins
its normal display of readings.

Communication connections
Use the information in Figure 2 (2700), Figure 3 (2701), or Figure 4 (2750) to con-
nect the desired communications port of the instrument.
WARNING Before making or breaking connections, turn off the instru-
ment, disconnect the line cord, and disconnect any external cir-
cuitry connected to the mainframe or switching modules.
Communication configuration
Factory communication settings
Models 2700 and 2750 – These Integra instruments are shipped from the factory
with the GPIB communications selected and set to primary address 16.
Model 2701 – This Integra instrument is shipped from the factory with the Ether-
net interface selected and with the following settings:
IP Address: 192.168.000.002
Subnet Mask: 255.255.255.000
Gateway: 192.168.000.001
The interface settings for your computer must be compatible with the interface set-
tings for the Model 27xx. You can change the interface settings for your computer
or you can change the interface settings of the Model 27xx.
Checking and/or changing Integra communications settings
Use the “Communications configuration” information in Figure 1 (2700), Figure 2
(2701), or Figure 3 (2750) to check and/or change communications settings. While in
the menu structure for a communication interface, use the edit keys (see Figure 5) to
check or change settings.
NOTE If you select the alternate interface type (e.g., enabling (ON) the
RS-232 while the GPIB is presently selected), the instrument will
reboot. You will have to re-enter the menu structure to check/change
the other settings.

Quick Start Guide Integra Series 11
Start-up software
Models 2700, 2701, and 2750 – You can use the “Up & Running with TestPoint”
software (supplied on CD) to perform the following:
• Control and configure the Integra instrument
• Scan, acquire, and graph the data
• Store data on disk for analysis
• Save and recall instrument scan configurations
Model 2701 – A built-in web page is available to allow for easy Ethernet communi-
cation between the instrument and the computer. From this web page, you can
read and set network parameters and other data stored in the Model 2701. It also
takes readings and allows you to send command strings and receive data.
Using Internet Explorer (IE 5.0 or greater), a local intranet address is used to open
the web page. The web page address is the same as the IP Address of the Model
2701. Assuming the default IP Address is being used, the following intranet
address will open the web page: http://192.168.0.2
NOTE Details on using the Ethernet web page with the Model 2701 is pro-
vided in Section 10 (see “Internal web page”) of the Model 2701
User’s Manual.
Trigger and return readings
Remote programming – The following SCPI command sequence is used to trig-
ger a finite number of measurements and return the readings. It is assumed that
Factory defaults have been previously restored.
INIT:CONT OFF ‘ Disables continuous measurements. Measurements will not
‘ be performed until the instrument is triggered.
TRIG:COUN <n> ‘ Sets the trigger count: <n> = 1 to 9999. This specifies the
‘ number of measurements to be performed.
READ? ‘ Triggers measurement(s) and requests reading(s).
Included with each returned reading is a timestamp and a reading number (Read-
ing, Timestamp, Reading Number). For example:
1.00000000E+01VDC, +8694.16SECS, +6141RDNG#
The 10VDC reading is returned in exponent format. When the Model 27xx was
turned on, the timestamp and reading number started at zero. For the above
example, the measurement occurred 8,694.16 seconds after the unit was turned
on, and the reading was the 6,141st taken since the unit was turned on.

Front panel input connections
NOTE Information on “Input connections and measurements” for the Model
7700 switching module is provided on page 35 of this guide.
Front panel input connections are shown in Figure 6. Note that the Front/Rear
INPUTS switch must be in the out (F) position in order to use the front panel
inputs.
2-wire measurements – The 2-wire connections to front panel inputs are shown in
Figure 6A. Use these connections for DCV, AVC, DCI, ACI, Ω2, FREQ, PERIOD, and
TEMP (thermistor) measurements. Notice that DCI and ACI measurements use the
AMPS and LO terminals shown in Figure 6A (e). All other 2-wire measurements use
the INPUT HI and LO terminals.
4-wire measurements – The 4-wire connections to front panel inputs are shown
in Figure 6B. Use these connections for Ω4 and TEMP (4-wire RTD) measure-
ments.
Maximum inputs (front panel)
The maximum allowable inputs for the front panel inputs are listed in Ta bl e 1 .
CAUTION To prevent damage to the Model 27xx, do not exceed the maxi-
mum allowable inputs shown in Table 1.
When using a switching module, the maximum allowable input
voltage anywhere in the test system (including front panel
inputs) is degraded to the maximum allowable input voltage of
the switching module. Maximum inputs for the Model 7700
switching module are listed in Table 2 on page 35.
Table 1
Maximum front panel inputs
Function Maximum input
