1. SetthefunctionswitchtotheWposition.
2.
InserttheblackprobeleadintothenegativeCOMterminalandtheredprobeleadinto
thepositiveWterminal.

3.
Pressthetriggertoopentheclampjaws.Fullyencloseoneconductor—refertoFigure5.1.
Foroptimumresults,centertheconductorinthejaws.
Note:The+symbolonthejawshouldbedirectedtowardthepowersource

4. Connect theprobeleadsinparalleltothepart undertest.
5.
Readtheactivepowervalueonthedisplay.
 Ifthevalueisdisplayedwithoutasign,thepowerisflowingfromthepowersourcetothe
load.
 Ifthevalueisdisplayedwithaminussign(–),thepowerisflowingfromthepowerloadto
thesource.
6. Tomeasureanddisplaythepowerfactor,press
theMODEbuttonrepeatedlyuntilthe 
indicatorisdisplayed.
7. Readthepowerfactorvalueonthedisplay.
 Ifthevalueisdisplayedwithoutasign,thephaseofthecurrentsignalislaggingbehind
thevoltagesignal(inductiveload).
 Ifthevalueisdisplayedwithaminussign(–),thephaseofthecurrentsignalisleadingthe
voltagesignal(capacitiveload).
8. Toreturntoactivepowermeasurements,presstheMODEbuttonrepeatedlyuntilneither
the
northe indicatorisdisplayed.

Ifanoverloadoccurs,thefollowingisdisplayed:
