OperatingInstructions
WARNING:Riskofelectrocution.High‐voltagecircuits,bothACandDC,areverydangerousandshouldbe
measuredwithgreatcare.
1. ALWAYSturnthefunctionswitchtotheOFFpositionwhenthemeterisnotinuse.
2. IfOLappearsinthedisplayduringameasurement,thevalueexceedstheselectedrange.
Changetoahigherrange.
3. Ifthemeterdoesnotswitchonwhenthefunctiondialisturnedtoanypositionotherthan
OFF,pleasecheckthebatteries.RefertotheBatteryInstallationsectionofthisguide.
AUTOPOWEROFF(APO)
TheAPOfeatureturnsthemeteroffafter15minutesofinactivity.TodisableAPO,holdthe
SELECTbuttonwhileturningthemeteron.Themeterwillemit5beepsindicatingthatAPOhas
beendisabled(theAPOclockiconwillnotbevisibleonthedisplay).Turnthemeteroffandthen
onagaintore‐enableAPO(theAPOclockiconwillbevisibleonthedisplaywhenAPOisactive).
AUTOMATICandMANUALRange
ThemeterdefaultstoAUTORangemodewhenitisswitchedON.Inthismodethemeter
automaticallyselectsthebestrangeforthemeasurementsbeingmadeandisgenerallythebest
modeformostmeasurements.Formeasurementsituationsrequiringthatarangebemanually
selected,performthefollowing:
1. PresstheRANGEbutton.The“AUTORANGE”displayindicatorwillturnoff.
2. PresstheRANGEbuttontostepthroughtheavailableranges.
3. ToexittheManualRangingmodeandreturntoAutoranging,pressandholdtheRANGE
buttonfor2seconds.
MAX/MINMemory
1. PresstheMAX/MINbuttontoactivatetheMAX/MINrecordingmode.ThedisplayiconMAX
willappear.Themeterwilldisplayandholdthemaximumreadingandwillupdateonlywhen
anewmaximumreadingoccurs.
2. PresstheMAX/MINbuttonagainandthedisplayiconMINwillappear.Themeterwill
displayandholdtheminimumreadingandwillupdateonlywhenanewminimumreading
occurs.
3. ToexitMAX/MINmodepressandholdtheMAX/MINbuttonfor2seconds.
Relativemode
Therelativemeasurementfeatureallowstheusertomakemeasurementsrelativetoastored
referencevalue.Areferencevoltage,current,etc.canbestoredwheresubsequent
measurementscanbemadeincomparisontothatstoredreferencevalue.Thedisplayedvalueis
thedifferencebetweenthereferencevalueandthemeasuredvalue.
1. Performameasurementasdescribedintheoperatinginstructions.
2. PresstheRELbuttontostorethereading;theRelativeindicator willappearonthedisplay.
3. Thedisplaywillnowindicatethedifferencebetweenthestoredandmeasuredvalue.
