WARNING:BeforeusingthemeterintheACVoltageDetectormode,verifythatthebatteries

arefreshbyconfirmingcharactersappearontheLCDwhenthefunctiondialisturnedtothe

areweakorbad.

Notes:

Voltagemaystillexistevenwithnoindicationgivenbythemeter.DonotsolelyrelyonNCV

detectiontodeterminethepresenceofvoltage.Socketdesign,insulationthicknessandother

factorsmayaffectreadings.

TheNCVindicatorLEDmayflashwhilemeasuringAC/DCvoltageduetothepresenceof

1. Disconnectthecommon(negative)testleadfromthebottomofthemeter.

2. Withthe functionswitchsettoanypositionexceptOFF,pressandholdtheNCVbutton.

3. Movethetipofthemeter

nearthevoltagesourceorconductorasshown.

4. Ifthevoltage detectedis>110VAC,thebeeperwillsoundandtheNCVindicatornearthe
