GeneralInspection
AfteryougetanewWaveformGenerator,itisrecommendedthatyoushouldmakea
checkontheinstrumentaccordingtothefollowingsteps:
1.Checkwhetherthereisanydamagecausedbytransportation.
Ifitisfoundthatthepackagingcartonorthefoamedplasticprotectioncushionhas
sufferedseriousdamage,donotthrowitawayfirsttillthecompletedeviceandits
accessoriessucceedintheelectricalandmechanicalpropertytests.
2.ChecktheAccessories
ThesuppliedaccessorieshavebeenalreadydescribedintheAppendixA:Enclosure
ofthisManual.Youcancheckwhetherthereisanylossofaccessorieswithreference
tothisdescription.Ifitisfoundthatthereisanyaccessorylostordamaged,please
getintouchwiththedistributorofICELMANAUSresponsibleforthisserviceorthe
ICELMANAUS'slocaloffices.
3.ChecktheCompleteInstrument
Ifitisfoundthatthereisdamagetotheappearanceoftheinstrument,orthe
instrumentcannotworknormally,orfailsintheperformancetest,pleasegetin
touchwiththeICELMANAUS'sdistributorresponsibleforthisbusinessortheICEL
MANAUS'slocaloffices.Ifthereisdamagetotheinstrumentcausedbythe
transportation,pleasekeepthepackage.Withthetransportationdepartmentorthe
ICELMANAUS'sdistributorresponsibleforthisbusinessinformedaboutit,a
