Although some in- struments and accessories would normally be used with non-haz- ardous voltages, there are situations where hazardous conditions may be present. This product is intended for use by qualified personnel who recog- nize shock hazards and are familiar with the safety precautions re- quired to avoid possible injury. Read the operating information carefully before using the product. 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 en- suring 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 instru- ment. 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, for example, setting the line voltage or replac- ing consumable materials. Maintenance procedures are described in the manual. The procedures explicitly state if the operator may per- form them. Otherwise, they should be performed only by service personnel. Service personnel are trained to work on live circuits, and perform safe installations and repairs of products. Only properly trained ser- vice personnel may perform installation and service procedures. Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connectorjacks 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. Users of this product must bc protcctcd from electric shock at all times. The responsible body must ensure that users arc prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact. Product users in these circumstances must bc trained to protect thcmsclves from the risk of electric shock. If the circuit is capable ofopcrating at or above 1000 volts. no conductive part of the circuit may be exposed. As described in the Intcmational Electrotechnical Commission (IEC) Standard IEC 664, digital multimctcr measuring circuits (e.g., Keithley Models I75A, 199,2000,2001, 2002. and 2010) arc Installation Category II. All other instruments signal terminals arc Installation Category I and must not bc connected to mains. Do not connect switching cards directly to unlimited power circuits. They are intended to bc used with impedance limited sources. NEVER connect switching cards directly to AC mains. When con- necting sources to switching cards, install protective devices to lim- it fault current and voltage to the card. Before operating an instrument, make sure the line cord is conncct- ed to a properly grounded power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear. cracks, or breaks before each use. 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 cntirc test system and discharge any capacitors before: connecting or disconnecting cables or jump- ers, 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 equip- ment may be impaired. Do not exceed the maximum signal levels of the instruments and ac- cessories, as defined in the specifications and operating informa- tion, and as shown on the instrument or test fixture panels, or switching card. When fuses are used in a product, replace with same type and rating for continued protection against fire hazard. Chassis connections must only be used as shield connections fat measuring circuits, NOT as safety earth ground connections. If you are using a test fixture, keep the lid closed while power is ap- plied to the device under test. Safe operation requires the use of a lid interlock. Ifa screw is present, connect it to safety earth ground using the wire recommended in the user documentation. The ! a symbol on an instrument indicates that the user should re- fer to the operating instructions located in the manual. The A symbol on an instrument shows that it can source or mea- sure 1000 volts or more, including the combined effect of normal and common mode voltages. Use standard safety precautions to avoid personal contact with these voltages. The WARNING heading in a manual explains dangers that might result in personal injury or death. Always read the associated infor- mation very carefully before performing the indicated procedure. The CAUTION heading in a manual explains hazards that could damage the instrument. Such damage may invalidate the warranty. Instrumentation and accessories shall not bc conncctcd 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 Icads. and input jacks, must be purchased from Keithlcy Instru- ments. 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 bc purchased from other suppliers as long as they are equivalent to the original component. (Note that se- lectcd parts should be purchased only through Keithley Instruments to maintain accuracy and functionality of the product.) If you arc 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 (e.g., data acquisition board for installation into a computer) should never require cleaning if handled according to in- structions. If the board becomes contaminated and operation is af- fected, the board should be returned to the factory for proper cleaning/servicing. Rev.
