The following safety precautions should be observed before using this product an d 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 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.

Safety Precautions

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 rate d 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 associated 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 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 60V DC 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 1000V, 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.

11/07

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.

AL W AYS 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.

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 information, 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 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. T o 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. 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 (for example, 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.

How do I power-up the instrument?

Step 1: Connect to line power

CAUTION Operating the instrument on an incorrect line voltage may cause damage

to the instrument, possibly voiding the warranty.

1. Before you plug the power cord into the Series 2600A, make sure that the front panel powe r 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. Connect the other end of the power cord to a grounded AC outlet.

WARNING Failure to use a grounded outlet may result in personal injury or

death due to electric shock.

Step 2: T urn on power

Turn on the instrum ent by pressing the front panel power switch to the on (I) position. Assuming no errors occur, the Series 2600A will power-up as follows:

1. The OUTPUT indicators and display pixels flash briefly.

2. The following items are shown in sequen ce :

• The firmware revision number.

• The line frequency.

• The TSP-Link node.

• The enabled command interface(s) and address (GPIB/LAN/RS-232).

Step 3: Set line frequency

The Series 2600A will operate at line frequencies of either 50Hz or 60Hz. For best measurement noise performance, the unit should be con fig ur ed to match the actual line frequency used by selecting MENU > LINE-FREQ > 50Hz, 60Hz, or AUTO (when set to AUTO, the SourceMeter will automatically detect the power line frequency at power-up).

Series 2600A System SourceMeter® Instruments User’s Manual Section 1: Front and Rear Panel Operation

How do I make measurements?

See the Series 2600A Reference Manual for more information on the following:

• Basic source-measure procedure.

• Ohms measurements.

• Power measurements.

The measurement procedure below demonstrates how to set up the Series 2600A to source 10V and measure current through a 10kΩ resistor.

WARNING Hazardous voltages may be present on the output and guard

terminals. To prevent electrical shock that could cause injury or death, NEVER make or break connections to the Series 2600A while the output is on. Power off the equipment from the front panel or disconnect the main power cord from the rear of the SourceMeter before handling cables connected to the outputs. Putting the equipment into standby does not guarantee the outputs are not powered if a hardware or software fault occurs.

Step 1: Connect the DUT

Connect a 10kΩ resistor to the SourceMeter Channel A HI and LO terminals as shown in

Figure 1-4. See the Series 2600A Reference Manual for complete connection information.

Step 2: Select source and set source level

Perform the following steps to select the voltage source and set the source value to 10V:

1. Press Channel A SRC to select the V-Source as indicated by the “V” units in the source field on the display. The flashing cursor indicates which value is presently selected for editing.

2. Press the up RANGE key, and select the 20V source range (Model 2611A/2612A/2635A/ 2636A) or 40V source range (Model 2601A/2602A). Use the lowest possible source range for best accuracy.

3. Use the CURSOR keys to move the cursor to the 10s digit, then press the navigation wheel to enter the EDIT mode (EDIT indicator is displayed).

4. Using the navigation wheel, set the source value to 10.0000V, then press the ENTER key or the navigation wheel.
