Operation



AC/DCMagneticFieldMeasurement

SwitchthemeterONbypressingandholdingthePOWERbuttonforatleasttwoseconds.Press

andholdtheFUNCTIONbuttontoselecteitherDCorACmagneticfieldmeasurement.Pressand

holdtheRANGEbuttonuntilthedesiredrange(1or2)isselected.Selectthedesiredunitof

measure(mTorG).



ForDCmagneticfieldmeasurements,thedisplaywillshoweithertheNorSindicator.Forthe

NorthPole,theNindicatorwillbeshown.Similarly,fortheSouthPole,theSindicatorwillbe

shown.ForACmagneticfieldmeasurements,thedisplaywillshowtheACindicator.Thedisplay

willnotshowtheNorSindicator.



Contactandpressthetestingmaterialtotheprobehead(seeFig1).Thedisplaywillshowthe

magneticfieldvaluealongwiththemeasurementunit(mTorG).



Figure1

Note:WhenthemeterispoweredON,thedisplaymayshowanon‐zerovalue;thisisbecauseof

environmentalinterference.Beforetakingameasurement,settheprobeattheoptimum

position.ToZerothedisplay,pressandholdthe▲and▼buttonsuntilthedisplayshowsthe

“0”valueandthedisplayflashestheZEROindicator.Themeterisnowzeroed.



DataHold

Duringthemeasurements,presstheHOLDbuttontofreezeadisplayedreading.Themeasured

valuewillbeheldandtheLCDwilldisplaytheHOLDsymbol.PresstheHOLDbuttonagainto

releasethedataholdfunction.
