Thefollowingexplanationisforwhentheupperlimitofmeasuredharmonicorderis50.Iftheupper
limitislessthan50,computationisperformedtotheupperlimit,andtheresultsaredisplayed.
Display A
• Displayfunctionoff:Showstheharmonicorder(1to50).
• V:Showsallrmsvoltages(computedvalues)fromthe1sttothe50thharmonic.Thisisthesameas
display C described below.
• A:Showsallrmscurrents(computedvalues)fromthe1sttothe50thharmonic.Thisisthesameas
display C described below.
• W:Showsallrmsactivepowers(computedvalues)fromthe1sttothe50thharmonic.Thisisthe
same as display C described below.
Display B
• V:ShowsthemeasuredvoltagefortheharmonicshownindisplayA.
• A:ShowsthemeasuredcurrentfortheharmonicshownindisplayA.
• W:ShowsthemeasuredactivepowerfortheharmonicshownindisplayA.
• V%:ShowstheharmonicdistortionfactorofvoltagefortheharmonicshownindisplayA.Whenthe
numberofdisplayeddigitsis5,thedisplayrangeis0.000to99.999and100.00to999.99%.

• V°:
• WhendisplayAisshowingthe1stharmonic(fundamental)
Shows the phase angle of the fundamental current with respect to the fundamental voltage. G
appears in front of the value when the current lags the voltage; d appears when the current leads
the voltage.
• WhendisplayAisshowingaharmonicbetween2and50
Shows the phase angle of the harmonic voltage with respect to the fundamental voltage. A minus
sign(–)appearsinfrontofthevaluewhentheharmoniclagsthe1stharmonic.Thedisplay
rangeis–180.0to180.0°.
• A°:
• WhendisplayAisshowingthe1stharmonic(fundamental)
 ThesameasV°.
• WhendisplayAisshowingaharmonicbetween2and50
Shows the phase angle of the harmonic current with respect to the fundamental current. A minus
sign(–)appearsinfrontofthevaluewhentheharmoniclagsthe1stharmonic.Thedisplay
rangeis–180.0to180.0°.
