Safety Precautions The following safety precautions should be observed before using this product and any associated instrumentation. Although some in- struments and accessories would normally be used w

17、ith 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 careful

18、ly before using the product. 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 6

19、0VDC are present. A good safety practice is to ex- pect that hazardous voltage is present in any unknown circuit before measuring. Before operating an instrument, make sure the line cord is connect- ed to a properly grounded power receptacle. Inspect the connecting cables, test leads, and jumpers fo

20、r 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 entire test system and discharge any capacitors before: connecting or disconnecting c

21、ables 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

22、 while standing on a dry, insulated surface capable of withstanding the voltage being measured. Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and operating informa- tion, and as shown on the instrument or test fixture panels, or switchin

23、g card. 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 main. When con- necting sources to switching cards, install protective devices to lim- it fault current and voltage t

24、o the 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 for measuring circuits, NOT as safety earth ground connections. If you are using a test fixture, keep the lid clos

25、ed 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 #18 AWG or larger wire. The t symbol on an instrument or accessory indicates that 1OOOV or more may be present on the terminals. Ref

26、er to the product man- ual for detailed operating information. Instrumentation and accessories should not be connected to hu- mans. Maintenance should be performed by qualified service personnel. Before performing any maintenance; disconnect the line cord and all test cables. TABLE OF CONTENTS Parag
