5.8EarthBondResistanceMeasurements(ZEROΩ)

1. MovethefunctiondialtotheEarth‐bondresistanceposition(ZEROΩ);theEarth‐bond

resistanceicon

willappear.

2. InserttheblackprobeleadintotheCOMterminalandredprobeleadintotheZEROOhm

terminal.

3. Beforetesting,shorttheendsoftheprobesandpresstheMODEbutton.TheZEROiconwill

appearonthedisplayandtheoffsetvaluewillbestored.

Ifthetestleadsarenotshortedorif

thereisresidualresistance,thedisplaywillshowthe>2.00ohms(thisindicationcouldbedue

tofaultyleads,impropertestleadinsertion,ormeterproblem.Testsshouldnotbeattempted

untilrootcauseofthehighresistanceisdetermined.

PressTESTOKtorunatest.

5. TolockthetestON,presstheHOLD/LOCKbutton(theLOCKicon willappear)andthen

pressTESTOKtotestcontinuously.

6. PressTESTOKagaintostopthetest.

7. NotethattheEarthBondResistanceMeasurementmodecanalsobeusedtomeasure

standardresistanceto40kohms



NOTE:The99pointDataRecordmemoryfunctioncannotbeactivatedin

theusualwaywhile

usingtheEarthBondResistancefunction(sincetheTESTOKbuttonisusedfortestinginthis

caseandnotforsavingreadings).Thelastreading,however,isheldonthedisplayandcanthen

besavedasdescribedintheExtendedFunctionalitysectionbelowunderSection5.12.8Data

5.9ContinuityTest

Warning:Donotdodiode,resistanceorcontinuitytestsbeforeremovingthepowerfrom

capacitorsandotherdevicesundertestduringameasurement.Injurytopersonscanoccur.



1. Setthefunctionswitchtothe position.

2. InserttheblackprobeleadintotheCOMterminalandredprobeleadintotheVterminal.

3. UsetheMODEbuttontoselectcontinuitymeasurement.The

indicatorwillbedisplayed.

4. InserttheblackprobeleadintotheCOM(negative)terminalandtheredprobeleadintothe

positiveterminal.

5. Touchthetipsoftheprobeacrossthecircuitorcomponentundertest.

6. Iftheresistanceis30±5Ω(nominal)orless,the

meterwillbeep.
