Electric and Magnetic Field Measurement
The EFA-300 is so powerful that even transient events ranging
up to 2 kHz can be analyzed in real time.
Evaluation is supported by graphics to clearly show the fre-
quency spectrum and by cursor functions with frequency
and level indications. The RMS and peak values of the nine
most significant frequency components are easy to read.
You can also use this mode to normalize the display to a given
standard. The measured value is then displayed relative to its
associated standard. In visual terms, the frequency-depen-
dent standard becomes a straight line. This makes it easy to
determine the relevancy of each spectral component.
Harmonic Analysis Mode
(Included with Spectrum FFT Mode)
This mode enables fast, convenient evaluation of the harmon-
ic spectrum. A table lists the field strengths of the measured
fundamental frequency along with up to 8 harmonics.
This feature is very useful for a “hands-off” verification of pow-
er quality (“Quality of Service”) in addition to occupational
safety applications.
