Introduction

ThankyouforselectingtheExtechInstrumentsTrueRMSMiniClampMeter.TheMA61

measuresACCurrentwhiletheMA63measuresACandDCCurrent.Bothmetersalsomeasure

AC/DCVoltage,Frequency,Resistance,Capacitance,Diode,andContinuity.



TheMiniClampMetersmeasurecurrentinthreeACranges600mA,6000mA,and60A.The

MA63onlymeasuresDCcurrentintworanges6000mADCand60ADC.



TheclampmetersofferadvancedfeaturesthatincludesNCV(non‐contactvoltage)detection

andVFC(variablefrequencycontrol)thatinsertsalowpassfilterinthemeasurementcircuit.



Thisdeviceisshippedfullytestedandcalibratedand,withproperuse,willprovideyearsof

reliableservice.Pleasevisitourwebsite(www.extech.com)tocheckforthelatestversionofthis

UserGuide,ProductUpdates,ProductRegistration,andCustomerSupport.

Operation

MeterPower

Caution:Donotusethemeterwithbatterycompartmentopenorunsecured.

Theclampmeterispoweredbytwo(2)AAAbatteries.Thebatterycompartmentislocatedonthe

backofthemeter.ThebatterycompartmentissecuredbyonePhillipsheadscrew.Refertothe

BatteryReplacementsectionlaterinthisguideformoreinformation.

AutomaticPowerOFF(APO)

Themeterautomaticallyswitchesoffafter15minutesofinactivity.Beforeswitchingoff,themeter

beepsseveraltimestoalerttheuser.TodisableAPO,holddowntheMODEbuttonwhilepowering

upthemeter.Themeterwillbeepfive(5)timesindicatingthatAPOisdisabled;releasethebutton.

NotethattheAPOiconisnotvisibleonthedisplaywhenAPOisdisabled.APOisre‐enabledon

thenextcyclingofmeterpower.
