7.4 User-specific Configuration
of the NFA
This part of NFAsoft allows for a customized user definable configuration of the
NFA. The configurations will be made available in the "CONFIG.NFA" file of your
NFA. The new settings are automatically loaded by the NFA upon its next start when
saved on the SD memory card.
Several customized pre-settings for NFAsoft can be defined allowing a quick ac-
cess. Simply select the settings as required and activate the button "save as pre-
setting for NFAsoft". All pre-settings are stored in the file "NFAsoft.ini" and are avail-
able for NFAsoft provided that this file is in the same folder.
"All3D" to be smaller than the indication for 16.7 Hz, as the signal components at
16.7 Hz are not integrated in the total sum of "All3D". Furthermore, the signals of the
different frequencies are added up quadratically, which in turn means that the result
of simply adding the individual signals will also differ from the sum of "All3D". (For
more information on this matter see chapter 9).

For a synchronization of
the time, the SD-card in
the meter should be con-
nected to your computer
via USB-cable. The syn-
chronization will either
take place automatically
once "CONFIG.NFA" is
recorded onto the SD-
card, or else the manually
entered time is applied at
that very moment.
If the high pass is set at
50 Hz, this only refers to
the broad band reading or
recording as it reduces
the influence of move-
ment induced field com-
ponents. For full infor-
mation, the frequency
components of sinusoidal
waves at exactly 16.7 Hz
are still recorded sepa-
rately and can be shown
with the help of the NFA-
soft.
If the filter is set, it is
therefore not unusual for
the summary indication
