12.5.1 Brief description
• Measurement of the magnetic flux density or electric field strength based
on spectrum analysis through a Fast Fourier Transformation.
• Determination of the exact fundamental frequency by entering
an approximate value
• Measurement of the field strength of the fundamental and harmonics.
12.5.2 Frequency range
12.5.3 Result display
The number of displayable harmonics is limited by the ratio of the selected
fundamental frequency and the available frequency range.
