The following safety precautions should be observed before using this product and any associated instrumentation. Although some
instruments an d accessorie s would n ormally be used with non-h azardous voltag es, there are situ ations where h azardous conditions ma y
be present.
This product is inte nded for us e by qualifi ed person nel who recognize s hock haz ards and are f amiliar w ith the safe ty precau tions requ ired
to avoid possible in jury. Read and follow all inst alla tio n, opera tion, an d mai ntenance i nfo rmatio n carefu lly b efore us ing 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 inten ded function. T hey must be trained in ele ctrical safety procedures a nd proper us e of the inst rument.
They must be protected from electric shock and contact with hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it op era tin g p r op erly, for example, settin g the li ne v oltage or
replacing consuma ble ma terials . Main tenanc e proc edures are descri bed in t he u ser docum ent ation. The proced ures expl icitly st ate if th e
operator may perform them. Otherwise, they should be performed only by service personnel.
Safety Precautions
Service personnel are trained to work on live circ uits, perform safe installa tions, and repair products. Only proper ly trained service
personnel may perform installation and service procedures.
Keithley Instruments 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 Ca tegory I and must not be dire ctly connected to ma ins voltage or to vo ltage sources wi th high transient
over-voltages. Measurement Category II connections require prote ction for high transient over-voltages often as sociated with local AC
mains connect ions. Assume all measurement, co ntrol, and dat a I/O connec tions are for c onnection to Cate gory I sources unless otherwise
marked or described in the user documentation.
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 acces s and/or insul ated from ev ery connect ion point . In some c ases, conne ctions mus t be expos ed to potenti al human c ontact.
Product operators in th ese ci rcu ms t ances must be train ed t o protect themselves from th e ri sk of electric shock. If the ci rcu it is capable of
operating at or above 1000V, no conductive part of the circuit may be exposed.
Do not connect switc hing cards direc tly to unlimite d power circui ts. They ar e intended to b e used with im pedance-limite d 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.
11/07
When install ing equipment where access to the main power cord is r estricted, such as rack mo unting, a separate main in put 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.
AL W AYS remove power from the entire test system and d ischarge an y capaci tors before: c onnecting or disconnect ing cables or jumpers,
installing or removing switching cards, or making internal changes, such as installing or removing jumpers.
Do not touch any o bject that could pro vide a curren t p ath to the com mon sid e of the circ uit under t est or p ower line (e arth) 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 maxi mum s ignal levels of the ins trume nts and a ccesso ries, as define d in the sp ecifi cation s and op erat ing info rmation,
and as shown on the instrument or test fixture panels, or switching card.
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 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 user documentation.
The symbol on an instrument shows that it can source or measure 1000V 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 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 th e u se r do cu me ntation explains hazards that could damage the instrum ent . Su ch 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.
T o main tain protecti on from electric sho ck and fire, replacem ent component s in mains circu its - includi ng the power transform er, tes t 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 function ality of the product). If you ar e unsure about the applicabi lity of a replacement co mponent, call a Keithley Ins truments
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 instrumen t or allow liqui ds to enter or spi ll on the inst rument. Produ cts tha t consist of a circ uit 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.

Connection warning
WARNING Connection information for switching modules is intended for qualified service
personnel. Do not attempt to connect DUT or external circuitry to a switching
module unless qualified to do so.
To prevent electric shock that could result in serious injury or death, comply with
these safety precautions:
Before making or breaking any connections to the switching module, make sure
the Series 3700 is turned off and power is removed from all external circuitry.
Do not connect signals that will exceed the maximum specifications of any
installed switching module.
Test lead insulation must be rated to the highest voltage connection when the
Series 3700 rear analog backplane connector and the switching module terminals
are simultaneously connected. For example, if 300V is connected to the analog
backplane connector, the test lead insulation for the switching module must also
be rated for 300V.
Dangerous, explosive electrical arcs that can cause severe personal injury or
death are possible if a multimeter that is set to a low-impedance range is
connected to a high-energy circuit, causing a "virtual short."
Dangerous arcing can result (even when the multimeter is set to a voltage range) if
the minimum voltage spacing is reduced in the external connections. For details
about how to safely make high energy measurements, see High-energy circuit
safety precautions in the Series 3700 Reference Manual.
IMPORTANT: Do not connect the Series 3700 to mains; it is designated Installation
Category I, as described in the International Electrotechnical Commission (IEC)
Standard IEC 664.
3700S-903-01 Rev. C / November 2008 5
Install the module
WARNING Slot covers must be installed on unused slots to prevent personal contact with
high-voltage circuits.

(2) Module (4) Mounting screw (part of module)
WARNING To prevent electric shock that could result in injury or death, NEVER handle a
switching module that has power applied to it.
Before installing (or removing) a switching module, make sure the Series 3700 is
turned off and disconnected from line power.
If the switching module is already connected to a device under test (DUT), make
sure power is removed from all external circuitry.

parameter. Pushing the navigation wheel has the same functionality as pressing the instrument front
panel ENTER key.
To maneuver within the active channel display:
• Pushing the navigation wheel has the same functionality as the Tab key on a PC. Each push of the
navigation wheel sequentially moves the selection through the four main display parameters: slot,
channel, end channel, and measurement function.
To configure a parameter in the active channel display:
• Push the navigation wheel until the desired parameter is highlighted: slot, channel, end channel, or
function.
• Rotate the navigation wheel to scroll to the desired measurement function or to edit the value of the
numeric parameter of the slot, channel, or end channel. Slot parameters are not configurable unless a
module is installed in that slot position.
• Push the navigation wheel or press the ENTER key to accept your changes.
To configure a parameter within a menu:
• Press the MENU key to enter the desired menu.
• Rotate the navigation wheel to scroll to the desired parameter (indicated by BOLD in the procedures
shown in this guide).
