Safety precaut ions
The following safety precautions should be observed before using this product and any associated instrumentation. Although
some instruments and accessories would nor ma lly 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 operator s
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 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.
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.
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 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 mark ed on the instr u ment .
The
symbol on an instrument means caution, risk of electr ic shock. Use standard safety precautions to avoid personal
contact with these voltages.
The
The
symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns.
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 h az ards that coul d dama ge 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 circu i ts — inc lud ing 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.

2. Before operating, ensure that the ambient temperature is between +0 °C and +40 °C (+32 °F to
+104 °F).
To ensure proper cooling, keep the front, sides, and rear of the instrument clear of
obstructions.
Use properly rated load wires. All load wires must be heavy enough not to overheat when
carrying the maximum short-circuit output current of the power supply. If there is more than
one load, then any pair of load wires must be capable of safely carrying the full-rated shortcircuit output current of the power supply.
To reduce risk of fire and shock, ensure the mains supply voltage fluctuations do not exceed
10% of the operating voltage range.
Do not loosen any screw on this product, except those in the rear connector, which are intended to
retain attached external wires to the connector. There are no user serviceable components inside.

Configuring the instrument for your application
The configuration menus (see Configuration menus description (on page 2-9)) include settings, like
OVP and Max Volt, that determine the maximum voltage output of the power supply. The menu
system also includes settings, like Save Last and Output Recall, that determine how the
instrument initializes itself when it is turned on.
This power supply features a constant voltage/constant current automatic crossover. This feature
permits continuous operation in the transition from constant-voltage mode to constant-current mode
as the load changes. The intersection of the constant-current and constant-voltage modes is called
the crossover point.
For example, if the load is such that the power supply is operating in constant-voltage mode, the
power supply provides a regulated output voltage. The output voltage remains constant as the load
increases until the preset current limit is reached. Then the crossover occurs. At that point, the output
current becomes constant and the output voltage drops in proportion to further load increases.
Crossover is indicated by the front panel CC and CV messages. If the CV message appears, the
instrument is operating in constant-voltage mode. If the CC message appears, the instrument is
operating in constant-current mode.
Crossover from the constant-current mode to the constant-voltage mode also occurs automatically in
response to a decrease in load. For example, suppose you are charging a 12 V battery. Initially, the
open circuit voltage of the power supply is preset for 13.8 V. A low-battery places a heavy load on the
power supply, and it operates in constant-current mode. You adjust the instrument to charge the
battery at the rate of 1 A. As the battery becomes charged and its voltage approaches 13.8 V, the
load decreases to the point where the battery no longer demands the full 1 A charging rate. The
power supply then crosses over to constant-voltage mode.
