Beforeservicingunitscoveredbythisservicemanualanditssupplements,readandfollowtheSafetyPrecautions sectionofthismanual.

NOTE

Ifunforeseencircumstancescreateconictbetweenthefollowingservicingprecautionsandanyofthesafetyprecautions, alwaysfollowthesafetyprecautions.Remember:SafetyFirst.

1.2.1.GeneralServicingPrecautions

1)a.Alwaysunplugtheinstrument’sACpowercordfromtheACpowersourcebefore(1)removingorreinstallingany component,circuitboard,moduleoranyotherinstrumentassembly,(2)disconnectinganyinstrumentelectricalplugor otherelectricalconnection,(3)connectingatestsubstituteinparallelwithanelectrolyticcapacitorintheinstrument.

b.Donotdamageanyplug/socketB+voltageinterlockswithwhichinstrumentscoveredbythisservicemanual mightbeequipped.

c.DonotapplyACpowertothisinstrumentandoranyofitselectricalassembliesunlessallsolid-statedeviceheat sinksarecorrectlyinstalled.

d.Alwaysconnectatestinstrument’sgroundleadtotheinstrumentchassisgroundbeforeconnectingthetestinstrument positivelead.Alwaysremovethetestinstrumentgroundleadlast.

5)Afterservicing,alwayscheckthattheremovedscrews,components,andwiringhavebeeninstalledcorrectlyandthat theportionaroundtheservicedparthasnotbeendamagedandsoon.

Further,checktheinsulationbetweenthebladesoftheattachmentplugandaccessibleconductiveparts.

1.2.2.InsulationCheckingProcedure

DisconnecttheattachmentplugfromtheACoutletandturnthepowerON.Connecttheinsulationresistancemeter(500V) tothebladesoftheattachmentplug.Theinsulationresistancebetweeneachbladeoftheattachmentplugandaccessible conductiveparts(seenote)shouldbemorethan1Megohm.

NOTE

Accessibleconductivepartsincludemetalpanels,inputterminals,earphonejacks,etc.
