Safety precautions

The following safety precautions s hould be observed before using this pr oduct 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 precauti ons required
to avoid possible injury. Read and follow all installation, operation, and maintenance information caref ully 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 maint enance of equipment, for ensuring that the
equipment is operated within its specifications and operating lim i ts, 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 pr oper use of the
instrument. They must be protect ed from electric shock and contact with hazardous live circuits.

Maintenance personnel perform r outine procedures on the product to keep it oper ating 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 m ay 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 products are designed f or 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 ins trument labels, do not connect an y ins trument 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 S tandards Institute (ANSI) states that a shock hazard exists when voltage lev els 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 o perators
are prevented access and/or insulated from every connection point. In some c ases, connections must be exposed to potential
human contact. Product operators in these circumstances must be trained to pr otect 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 direc tly 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 v oltage to the card.

Before operating an instrument, ens ure that the line cord is connected to a pr operly-grounded power receptacle. Inspect the
connecting cables, test leads, and j um pers for possible wear, cracks, or breaks before each use.

When installing equipment where ac cess 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 s ystem and discharge any capacitors before: connecting or disconnecting
cables or jumpers, installing or removing switching cards, or making int er nal changes, such as installing or rem oving jumpers.

Do not touch any object that could pr ov ide a current path to the common side of the c i r cuit 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 acc essories must be used in accordance with the operating instructions. If the instr uments or
accessories are used in a manner not s pec i fied in the operating instruction s , 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 inf or mation and shown on the instrument panels, test fixture panels, and s witching cards.

When fuses are used in a product, replace with the same type and rating for contin ued protection against fire hazard.
Chassis connections must only be used as shield connections for measuring c i r cuits, NOT as protective earth (saf ety ground)

connections.
If you are using a test fixture, keep the lid closed while power is applied to the dev ice under test. Safe operation requir es the use

of a lid interlock.

symbol is on a product, it indicates that mercury is present in the display l am p. 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 hazards 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 inst r ument. 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 elect ric shock and fire, replacement components in mains circuits — including t he power

transformer, test leads, and input jac ks — must be purchased from Keithle y. Standard fuses with applicable nat ional 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 purchas ed from other
suppliers as long as they are equival ent to the original component (note that selected parts should be purchased only through
Keithley to maintain accuracy and functionality of the product). If you are unsure about the applicability of a replacement
component, call a Keithley office f or i nformation.

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 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 factor y for proper cleaning/servicing.

Reference Manual

2: General operation 2606B System SourceMeter® Inst rument

Installing the 2606B

The 2606B is intended for mounting in a rack only. For detailed instructions, refer to the
documentation for the Model 4299-13 Rack Mount K i t (part number 0713574).

Rack mounting the 2606B requires two people. Failure to recognize and observ e stan dard
safety precautions could result in personal injury.

Cooling vents

The 2606B has front and side intakes and rear exhaust vents. All sides must be unobstructed to allow
for air flow and to dissipate heat.

Excessive heat could damage the 2606B and deg rade its performance. Only operate the 2606B in an
environment where the ambient temperature does not exceed 50 °C.

To prevent damaging heat build-up and ensure specified performance, use the following
guidelines.

The rear exhaust vents and both side intake vents, and the front intake vents must be



unobstructed to properly dissipate heat. Even partial blockage could impair proper
cooling.

Do not position any devices adjacent to the 2606B that force air (heated or unheated)



toward its cooling vents or surfaces. This additional airflow could compromise accuracy.
When rack mounting the 2606B, make sure there is adequate airflow around both sides of



the instrument to ensure proper cooling. Adequate airflow enables air temperatures
within approximately one inch of the 2606B surfaces to remain within specified limits
under all operating conditions.

The front and sides of the 2606B are cool air intakes. It is recommended that there is



23 °C ±5 °C air available at these locations. Th e r ear of the 2606B is the exhaust.
If you rack mount high power-dissipation equipment next to the 2606B, it could cause



excessive heating. To produce specified 2606B accuracies, maintain the specified
ambient temperature around the intake vents of the 2606B. In rack configurations with
convection cooling only, which is not recommended, proper cooling practice places the
hottest non-precision equipment (for example, the power supply) at the top of the rack
away from and above precision equipment ( su ch as the 2606B).

Mount precision equipment as low as possible in the rack, where temperatures



are coolest.

Starting up your instrument

The following topics describe how to power your i nstrument on and off, place the instrument in
standby, configure the line frequency, and replace the line fuse.

Turning the instrument on and off

The 2606B operates from a line voltage of 100 V to 240 V at a frequency of 50 Hz or 60 Hz. Line
voltage is automatically sensed (there are no switches to set). Make sure the operating voltage in
your area is compatible.

Follow the procedure below to connect the 2606B to line power and turn on the instrument.

Operating the instrument on an incorrect line voltage may cause damage to the instrument,
possibly voiding the warranty.

To turn a 2606B on and off:

1. Before plugging in the power cord, make sure that the front panel POWER switch is in the off (O)
position.

2. Connect the female end of the supplied power cord to the AC receptacle on the rear panel.

3. Connect the other end of the power cord to a grounded AC outlet.

The power cord supplied with the 2606B contains a separate protective earth (safety ground)
wire for use with grounded outlets. When proper connections are made, the instrument
chassis is connected to power-line ground through the ground wire in the power cord. In
addition, a redundant protective earth connection is provided through a screw on the rear
panel. This terminal should be connected to a known protective earth. In the ev ent of a
failure, not using a properly grounded protective earth and grounded outlet may result in
personal injury or death due to electric shock.

Do not replace detachable mains supply cords with inadequately rated cords. Failure to use
properly rated cords may result in personal injury or death due to electric shock.
