Alwaysremove the test instrument ground lead last.Insulation Checking ProcedureDisconnect the attachment plug f rom the AC outlet and turn thepower on. Connect an insulation resistance met

25、er(500V) to theblades of the attachment plug. The insulation resistance betweeneach blade of the attachment plug and accessible conductive parts(Note 1) should be more than 1M-ohm.Note 1 : Accessible Conductive Parts including Metal panels, Inputterminals, Earphone jacks, etc.Electrostatically Sensi

26、tive (ES) DevicesSome semiconductor (solid state) devices can be damaged easily bystatic electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical Esdevices are integrated circuits and some f ield ef f ect transistors andsemiconductor chip componen

27、ts.The f ollowing techniques should be used to help reduce theincidence of component damage caused by static electricity.1. Immediately bef ore handling any semiconductor component orsemiconductor-equipped assembly, drain of f any electrostaticcharge on your body by touching a known earth ground.Alt

28、ernatively, obtain and wear a commercially availabledischarging wrist strap device, which should be removed f orpotential shock reasons prior to applying power to the unit undertest.2. Af ter removing an electrical assembly equipped with ES devices,place the assembly on a conductive surf ace such as

29、 aluminumf oil, to prevent electrostatic charge buildup or exposure of theassembly.3. Use only a grounded-tip soldering iron to solder or unsolder ESdevices.4. Use only an antistatic solder removal device. Some solderremoval devices not classif ied a “anti-static” can generateelectrical charges suf

30、f icient to damage ES devices.5. Do not use f reonpropelled chemicals. These can generateelectrical charge suf f icient to damage ES devices.6. Do not remove a replacement ES device f rom its protectivepackage until immediately bef ore you are ready to install it. (Mostreplacement ES devices are pac

31、kaged with leads electricallyshorted together by conductive f oam, aluminum f oil, orcomparable conductive material).7. lmmediately bef ore removing the protective material f rom theleads of a replacement ES device, touch the protective material tothe chassis or circuit assembly into which the devic

32、e will beinstalled.Caution : Be sure no power is applied to the chassis or circuit, andobserve all other saf ety precautions.8. Minimize bodily motions when handing unpackaged replacementES devices. (Normally harmless motion such as the brushingtogether of your clothes f abric or the lif ting of you
