Models 2634B, 2635B, and 2636B System SourceMeter® Instruments Quick Start Guide Safety precautions Observe the following safety precautions before using this product 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 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 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 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 Category I and must not be directly connected to mains voltage or to voltage sources with high transient overvoltages. Measurement Category II connections require protection for high transient overvoltages 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. Main supply voltage fluctuations not to exceed ±10 % of the nominal voltage. 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 V 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 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. 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 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. This symbol on an instrument means caution, risk of danger. The user should refer to the operating instructions located in the user documentation in all cases where the symbol is marked on the instrument. This symbol on an instrument means caution, risk of electric shock. Use standard safety precautions to avoid personal contact with these voltages. This symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns. This symbol indicates a connection terminal to the equipment frame. If the mercury 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. WARNING This 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. CAUTION This 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. To 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, remove power from the 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 and servicing. Power and environmental specifications For indoor use only.

Connect the instrument Important test system safety information This product is sold as a stand-alone instrument that may become part of a system that could contain hazardous voltages and energy sources. It is the responsibility of the test system designer, integrator, installer, maintenance personnel, and service personnel to make sure the system is safe during use and is operating properly. You must also realize that in many test systems a single fault, such as a software error, may output hazardous signal levels even when the system indicates that there is no hazard present. It is important that you consider the following factors in your system design and use: The international safety standard UL 61010-1 defines voltages as hazardous if they exceed 30 V RMS and 42.4 V peak, or 60 V DC for equipment rated for dry locations. Keithley Instruments, Inc. products are only rated for dry locations. Read and comply with the specifications of all instruments in the system. The overall allowed signal levels may be constrained by the lowest rated instrument in the system. For example, if you are using a 500 V DC power supply with a 300 V DC rated switch, the maximum allowed voltage in the system is 300 V DC. Make sure any test fixture connected to the system protects the operator from contact with hazardous voltages, hot surfaces, and sharp objects. Use shields, barriers, insulation, safety interlocks, and so on to accomplish this. Cover the device under test (DUT) to protect the operator from flying debris in the event of a system or DUT failure. Double-insulate all electrical connections that an operator can touch. Double insulation ensures that the operator is still protected even if one insulation layer fails. Refer to IEC 61010-1 for specific requirements. Make sure all connections are behind a locked cabinet door or other barrier. This protects the system operator from accidentally removing a connection by hand and exposing hazardous voltages. Use high-reliability fail-safe interlock switches to disconnect power sources when a test fixture cover is opened. Where possible, use automatic handlers so that operators are not required to access the DUT or other potentially hazardous areas. Provide training to all users of the system so that they understand all potential hazards and know how to protect themselves from injury. In many systems, during power up, the outputs may be in an unknown state until they are properly initialized. Make sure the design can tolerate this situation without causing operator injury or hardware damage. To keep users safe, always read and follow all safety warnings provided with each of the instruments in your system. Install the instrument The Series 2600B can be used on a bench or in a rack. See the instructions that came with your rack-mount kit if you are installing the Series 2600B in a rack. Note that the air intakes for the fan are located on the top cover and side panels of the Series 2600B. The space around these areas should be free from obstruction to ensure proper fan operation. Connect line power The Series 2600B 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. The power cord supplied with the Series 2600B contains a separate 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. Failure to use a grounded outlet may result in personal injury or death due to electric shock. 3. Connect the plug of the power cord to a grounded AC outlet. Operating the instrument on an incorrect line voltage may cause damage to the instrument, possibly voiding the warranty. To connect line power: 1. Make sure the front panel power switch is in the off (0) position. 2. Connect the socket of the supplied power cord to the power connection on the rear panel. Turn on the instrument Turn on the instrument by pressing the front panel POWER switch to the on (|) position. Power-up sequence When the instrument is turned on, you should see: A series of dots. All segments of the display light. A brief display showing the instrument model. For example, if the instrument is a Model 2635B, the display will show “KEITHLEY Model 2635B.” Line frequency detection and other startup checks. The entire power-up process takes approximately 30 seconds to complete. When initialization is complete, if the instrument is a Model 2634B or a Model 2636B, you will see the default display screen, shown below. If the instrument is a Model 2635B, you will see the default display screen, shown below. Test the instrument The following test verifies basic operation of the Model 2634B, Model 2635B, and Model 2636B. In this test, you will use the front-panel controls shown below to source voltage and measure the voltage output.
