Fluke 31
Clamp Meter True RMS
Description
This Clamp Meter gives accurate True RMS current measurements from 0.3 to 700A max.
In addition, the Model 33 captures peak values, up to 1000A, for Crest Factor calculation.
Both models measure frequency, so you can use them to determine the output frequency of adjustable speed drives, to set the governor of an engine generator or to detect third harmonic currents (180Hz) in the neutral of a 3 phase system.
This unit built extra strong to withstand job site abuse.
Key Points
True rms AC current measurement

Min/Max records maximum, minimum and average RMS current or frequency values
Auto/Manual Ranging
Crest measurement of the peak of the current waveform
Used to determine Crest Factor which can indicate the presence of harmonics
Smoothing displays a 3 second running average of current or frequency
