CAUTIONS

 Beforemaki nga measurement,chec kifthelowbatterysymbol isshownonthedisplay

whenthemeterisswitchedon.Replac ethebatteryifthesymbolisdisplayed.

 Inthecaseofprolongedstorage,removethebatteryfromthemetertopreventdamage.

 Donotexposethisdevicetodirectsunlightortoextremetemperaturesandhumidity.

 Theaccuracyandfunctionofthemetermaybeadverselyaffectedifthespecifiedlimitsareexceededorif

themeterishandledimproperly.

WARNINGS

 Usecautionwhenworkinginthevicinityofpowerfulradiationsources.

 Personswithelectronicimplant s (e.g.cardiacpacemakers)shouldavoidpow erfulradiationsources .

 Observeallrelevantsafetyregulations.

 Carefullyreadtheoperatinginstructionsforequipmentgeneratingorconductingelectromagnetic

energythatwillbemeasured.

 Donot

operatenearcombustiblegasesorindampenvironments.

 Beawarethatthefieldstrengthinthenearvicinityofradiatorsincreasesproportionallytotheinverse

cubeofthedistance.Thismeansthatenormousfieldstrengthscanresultintheimmediatevicinityof

smallradiationsources(e.g.leaksinwaveguides

orinductiveovens).

 Fieldstrengthmeasurementdevicescanunderratepulsedsignals,particularlywithradarsignals,inwhich

casesignificantmeasurementerrorscanresult.

 Allfieldstrengthmeasuringdeviceshavealimitedspecifiedfrequencyrange.Fieldswithspectral

componentsoutsideofthisfrequencyrangearegenerallyincorrectlyevaluatedandtend

tobe
