Safety PrecautionsThe following safety precautions should be observed before us

17、ing this product and any associated instrumentation. Althoughsome instruments and accessories would normally be used with non-hazardous voltages, there are situations where hazardousconditions may be present.This product is intended for use by qualied personnel who recognize shock hazards and are fa

18、miliar with the safety precautionsrequired to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before us-ing the product. Refer to the manual for complete product specications.If the product is used in a manner not specied, the protection prov

19、ided by the product 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 equip-ment is operated within its specications and operating limits, and for ensuring that operators are adequate

20、ly trained.Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of theinstrument. They must be protected from electric shock and contact with hazardous live circuits.Maintenance personnel perform routine procedures on the product to

21、 keep it operating properly, for example, setting the linevoltage or replacing consumable materials. Maintenance procedures are described in the manual. The procedures explicitly stateif the operator may perform them. Otherwise, they should be performed only by service personnel.Service personnel ar

22、e trained to work on live circuits, and perform safe installations and repairs of products. Only properlytrained service personnel may perform installation and service procedures.Keithley products are designed for use with electrical signals that are rated Installation Category I and Installation Ca

23、tegory II,as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most measurement, control, and dataI/O signals are Installation Category I and must not be directly connected to mains voltage or to voltage sources with high tran-sient over-voltages. Installation Cate

24、gory II connections require protection for high transient over-voltages often associated withlocalAC mains connections.Assume all measurement, control, and data I/O connections are for connection to Category I sourc-es unless otherwise marked or described in the Manual.Exercise extreme caution when

25、a shock hazard is present. Lethal voltage may be present on cable connector jacks or test xtures.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 haza

26、rdous voltage is present in any unknowncircuit before measuring.Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operatorsare prevented access and/or insulated from every connection point. In some cases, connections must be exposed t

27、o potentialhuman 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 volts, no conductive part of the circuit may be exposed.Do not connect switching cards directly to unlimite

28、d power circuits. They are intended to be used with impedance limited sourc-es. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective de-vices to limit fault current and voltage to the card.Before operating an instrument, make sure the lin

29、e cord is connected to a properly grounded power receptacle. Inspect the con-necting 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 pow-er d

30、isconnect 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 undertest. ALWAYS remove power from the entire test system and discha

31、rge any capacitors before: connecting or disconnecting ca-bles 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

32、(earth) ground.Al-waysmakemeasurementswithdryhandswhilestandingonadry,insulatedsurfacecapableofwithstandingthevoltagebeingmeasured.The instrument and accessories must be used in accordance with its specications and operating instructions or the safety of theequipment may be impaired.Do not exceed th

33、e maximum signal levels of the instruments and accessories, as dened in the specications and operating in-formation, and as shown on the instrument or test xture panels, or switching card.When fuses are used in a product, replace with same type and rating for continued protection against re hazard.C

34、hassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground connections.If you are using a test xture, keep the lid closed while power is applied to the device under test. Safe operation requires the useof a lid interlock.If ascrew is present, connec

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 associatedinformation very carefully before performing the indic

37、ated procedure.The CAUTION heading in a manual explains hazards that could damage the instrument. Such damage may invalidate the war-ranty.Instrumentation and accessories shall not be connected to humans.Before performing any maintenance, disconnect the line cord and all test cables.To maintain prot

38、ection from electric shock and re, 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 ap-provals, may be used if the rating and type are the same. Other co

39、mponents that are not safety related may be purchased fromother suppliers as long as they are equivalent to the original component. (Note that selected parts should be purchased onlythrough Keithley Instruments to maintain accuracy and functionality of the product.) If you are unsure about the appli

40、cabilityof a replacement component, call a Keithley Instruments ofce for information.To clean an instrument, use a damp cloth or mild, water based cleaner. Clean the exterior of the instrument only. Do not applycleaner directly to the instrument or allow liquids to enter or spill on the instrument.

41、Products that consist of a circuit board withno case or chassis (e.g., data acquisition board for installation into a computer) should never require cleaning if handled accord-ing to instructions. If the board becomes contaminated and operation is affected, the board should be returned to the factor
