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 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 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 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 properly­grounded 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.

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

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.

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 danger. 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 caution, 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

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 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 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., 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.

Attach pouches to the test fixture

Before installing the test fixture, attach the pouches (part number
8010-318) to the sides of the fixture, as shown here.

One pouch can be used to store the Interconnection Reference
Guide and the other can be used to store Model 8010 cables and
accessories.

To attach the pouches:

1. Make sure that the areas to which you want to attach the pouches
are clean. If you need to clean the test fixture, use a soft, lint-free
cloth and 70 percent isopropyl alcohol.

2. Close the lid of the test fixture.

3. Remove the protective backing from the hook and loop fastener
strips.

4. Position the pouch. Make sure placement of the pouch does not
interfere with the closing of the lid or your ability to use the
handles.

5. Press firmly.

8010 placement considerations

The Model 8010 is intended for use on a bench. Make sure you have
enough clearance to open the lid.

Assumptions for connection diagrams

When you use the connection diagrams in this Interconnection
Reference Guide, be aware of the following assumptions.

SourceMeter® Instrument information

You cannot use a Model 2651 and Model 2657 simultaneously to test
a single device.

You can use a Model 2651 or Model 2657 simultaneously with a
Series 2600 instrument. When a Series 2600 is referenced in the
Model 8010 documentation, you can use any of the following
SourceMeter Instruments:

 Model 2611
 Model 2612
 Model 2635
 Model 2636

Using remote sense

If you are using remote sense connections, you must enable remote
sense on the instrument.

Types of devices

All three-terminal devices under test (DUTs) are assumed to be
MOSFETs. Therefore, the labels G-D-S on the connection diagrams
relate to the Gate, Drain, and Source of a MOSFET device.

If you are testing an insulated gate bipolar transistor (IGBT), make
the following substitutions:

 G: Connect to the gate
 D: Connect to the collector
 S: Connect to the emitter

If you are testing a bipolar junction transistor, make the following
substitutions:

 G: Connect to the base
 D: Connect to the collector
 S: Connect to the emitter

Note: Remove the 4200-PA Remote Preamplifier when the
4200-SCS is connected to the Model 8010 or to the CVU-3K-KIT
bias tees.

Insulating plug use

The Model 8010 comes with insulating plugs that can be used when
testing two-terminal devices.

The three-pin socket inherently shorts the force and sense pins
together. When you are using the axial terminal posts in 4-wire mode,
this can cause measurement errors. You should insert the insulating
plug into the three-pin socket when testing axial-lead devices in
4-wire sense mode where a short between force and sense will cause
measurement errors.

Do not use the insulating plug when testing higher resistance devices
(greater than 1 MΩ). Using the plug for these tests may cause leakage

measurement errors.

Testing two-terminal TO-247 devices

The two-terminal interconnection diagrams that are shown in this
document are intended for axial-lead devices. However, you can
adapt the setups so that you can test two-terminal TO-247 devices.

To test TO-247 devices, you need to:

1. Remove the insulating plug (if used) from the three-pin socket.

2. Verify that the four axial device terminal posts are not connected
to anything.

3. Place the two-terminal TO-247 device into the three-pin socket.

Using both sides of the test fixture

In several of the interconnection diagrams, it is noted that you can
make equivalent connections on the other side of the test fixture. For
example, if you have an ongoing test using the Series 2600 connected
to the high-current side, you could set up a one-time test using the
equivalent terminals on the high-voltage side.

Note that this option is not available for test setups when you are
using a Model 2651 or Model 2657.

Do not simultaneously connect terminals in the high current and
high voltage areas of the fixture to the same terminals in the
center area (the area bordered in blue). S imultaneous
connections can result in electric shock (see previous graphic).

Connect the test fixture external wiring (current-voltage)

Important test system safety information

This product is sold as a stand-alone test fixture that may become
part of a system that could contain hazardous voltages and energy
sources. It is the responsibility of the test system designer, integrator,
installer, maintenance personnel, and service personnel to make sure
that the system is safe during use and that it is operating properly.

It is important that you consider the following factors in your system
design and use:

 The international safety standard UL 61010-1: 2004 defines

voltages as hazardous if they exceed 30 V RMS and 42.4 V peak,
or 60 V DC for equipment rated for dry locations. Keithley
Instruments products are only rated for dry locations.

 Read and comply with the specifications of all instruments in the

system. The overall allowed signal levels may be constrained by
the lowest rated instrument in the system. For example, if you are
using a 500 V power supply with a 300 V DC rated switch, the
maximum allowed voltage in the system is 300 V DC.

 Make sure any test fixture connected to the system protects the

operator from contact with hazardous voltages, hot surfaces, and
sharp objects. Use shields, barriers, insulation, and safety
interlocks to accomplish this.

 Provide training to all system users so that they understand all

potential hazards and know how to protect themselves from
injury.

Never connect the guard t erminal from any instrument to the LO
terminal of any instrument in the Model 8010 or to the chassis.
Connecting guard to LO can disable the high voltage protection
that is installed across the Model 4200 or Model 2600
SourceMeter Instrument connections. This may result in
hazardous live voltages being present at the HI, SHI, SLO, or LO
terminals.
