The following safety precautions should be observed before using this product and any associated instrumentation. Although some instruments an d access ories would n ormally be used with non-h azardous voltag es, there are situ ations where h azardous condition s may be present.

This product is inte nded for us e by qual ified person nel who recognize s hock haz ards and are famili ar with the s afety prec autions requ ired to avoid possible in jury. Read and follow all inst alla tio n, opera tion, an d mai ntenanc e info 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 e lectrical safe ty 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 wor k on live circuits, perform safe installations, and repair products. Only pro perly 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 voltag e or to voltage sourc es with high transient over-voltages. Measurement Category II connections require protection for high transient over-voltages oft en associated with local AC mains connect ions. Assume all measurement, co ntrol, and dat a I/O connec tions are for conn ection to Cate gory I sources u nless 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 p r otec t themselves from the 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 unlim ited power circui ts. They ar e intended to b e used with im pedance-lim ited 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 d ischarge an y capa citors befo re: connecting or disconne cting cab les 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 c urrent p ath to the com mon sid e of the c ircuit 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 tru ment s and acces sories , as defi ned in th e spec ifica tion s and op erating 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 l id

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 m ay be hot. Avoid personal c ontact 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 ha za rds th at could damage the i nst rum ent. Such damage ma y inv al ida te 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 trans former, 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 circuit board wi th 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.

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

How do I make measurements?

Reference For more detailed information, see the following information in Section 4 of the

Series 2600 Reference Manual:

• "Basic source-measure procedure"

• "Ohms measurements"

• "Power measurements"

The measurement procedure below demonstrates how to set up the Series 2600 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 2600 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 on page 1-14 (Models 2601/2602/2611/2612) or Figure 1-5 on page 1-15 (Models

2635/2636). See Section 3 of the Series 2600 Reference Manual for complete 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 2611/2612/2635/2636)

or 40V source range (Model 2601/2602). 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 displays).
