6 Operating modes
6.1 Field Strength mode
The magnetic flux density or the electric field strength (RMS value or peak
value) within a selected frequency range is determined in “Field strength”
mode.
Frequency range classes
You can select one of the following three frequency range classes
(frequency filters):
Frequency measurement
A frequency measurement is additionally performed for the “BROAD BAND”
frequency range class.
This frequency measurement is based on counting the number of zero
crossings of the signal and is therefore basically suitable for measuring
fields with one dominant frequency.
The field strength required for a measurement depends on the selected
measurement range.

class
Explanation
BROAD BAND
(broadband filter)
Measurement of all the signal components that are within a
selected (broad) frequency range.
BAND PASS
(bandpass filter)
Measurement of all the signal components that are within a
narrow frequency range.
BROAD BAND
(stop band filter)
Measurement of all the signal components that are within the
frequency range [5
Hz to 2 kHz] with the exception of a
narrow frequency range. The signals in this “unwanted”
frequency range are suppressed.
