5.6.3.6MIN/MAX/AVGMode
InMin/Max/Avgmode,themetercapturesanddisplaystheminimumormaximumvalues
andupdatesonlywhenahigher/lowervalueisregistered.Themetercanalsodisplaythe 
averageofallvaluesrecordedfromthebeginningofMin/Max/Avgmode.
1. Usethenavigationbuttonstoselect andenableMin/Max/Avgmode.
2.
PresstheOKbuttonrepeatedlytocyclethroughtheminimum,maximum,andaverage
readingdisplays.Thecorrespondingiconsaredisplayed:
, ,or .

5.6.3.7HarmonicDistortionMode

InHarmonicDistortionmode,themeterdisplaysthedistortionpercentagevalueforthe
first25harmonicsaswellasthetotalharmonicdistortion.HarmonicDistortionmodeis
availablewhenmeasuringACcurrentorvoltageinManualselectmode.
TheharmonicdistortionisexpressedasH

=(RMSofanindividualharmonicn)/(RMSofthe
fundamentals)×100%.
1. Usethenavigationbuttonstoselect andenableHarmonicDistortionmode.
2.

5.6.3.8VFDMode(lowpassfilter)
The VFD mode eliminates high frequency noise in voltage measurements by means of a low-
pass filter. The VFD mode is designed for variable frequency drive (VFD) measurements. This
mode is available for measurements of AC current or voltage.
1. Use the navigation buttons to select
and activate the VFD mode
5.7Non‐ContactVoltageDetector
Note:Testonaknownlivecircuitbeforetestingonanunfamiliarcircuit.
1. Holdtheclamptipsofthemeterveryclosetothevoltagesource.
2.
Ifvoltageispresent,thenon‐contactvoltagealertlamp(seesection4.1Meterparts)
illuminatesaredcolor.
CAUTION
Ifthenon‐contactvoltagealertlampisnotilluminated,voltagecouldstillbepresent.
