Introduction

ThankyouforselectingtheExtechMA260200ATrueRMSOpenJawClampMeter.TheMA260

incorporatesAutoSensingwherethemeasurementtypeisautomaticallysensedandconfigured,

noneedtoturnadialtoselectthemeasurementtypeorrange.ForACVoltage,theAuto‐sense

featurealsoevaluatesinputsignalsandadjuststheInputImpedancetoeliminateeffectsofghost

voltages.

TheMA260measuresACcurrent,AC/DCVoltage,Resistance,Continuity,andDiodeandoffers

extra‐largedisplaydigits,datahold,andadisplaybacklightfunction.Thenon‐contactVolt‐

Detectionfeaturesenseselectricalsourcessafely.



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

CleaningandStorage

Periodicallywipethecasewithadampclothandmilddetergent;donotuseabrasivesorsolvents.

Ifthemeterisnottobeusedfor60daysormore,removethebatteriesandstorethemseparately.

BatteryReplacement

1. Removethesmall(middle)Phillipsheadscrewatthebackofthemeter.

2. Openthebatterycompartment

3. Replacethetwo1.5VAAAbatteriesobservingcorrectpolarity.

4. Re‐assemblethemeterbeforeuse

5. Safety:Pleasedisposeofbatteriesresponsibly;neverdisposeofbatteriesinafire,batteries

mayexplodeorleak;nevermixbatterytypes,installnewbatteriesofthesametype.



Neverdisposeofusedbatteriesorrechargeablebatteriesinhouseholdwaste.

Asconsumers,usersarelegallyrequiredtotakeusedbatteriestoappropriate

collectionsites,theretailstorewherethebatterieswerepurchased,or

whereverbatteriesaresold.

Disposal:Donotdisposeofthisinstrumentinhouseholdwaste.Theuseris
