How to Measure
and Data-Log
5.1
“Live”-Measurement
Of course the meter can be used the “conventional” way:
simply switch it on, set the required measurement parame-
ters, and read the values recorded. When operating in the
conventional mode, the “Status-LED” will be yellow.
In addition, the device is capable of logging all settings as
well as the measurement values of all four channels at once
(i.e. the three field axis values plus one additional channel).
This data is stored onto an SD-card for future analysis. This
function can be activated by temporarily switching the
“Power” switch to “Log.” until the status LED turns yellow.
Then switch the “Power” switch back to “On”. Please note:
When logging with the power switch set to ”LOG” and
changing the field of measurement and recording (for in-
stance from M3D to E3D), this will cause the recording ses-
sion to be closed and a new log file to be created.
These recordings can be annotated by real-time audio re-
cordings which will be assigned automatically to the respec-
tive measurement for replay.
The following chapters 5.2 and 5.3 are only relevant for
the NFA 1000.
5.2
Guided 9 Point Measurement
of Sleeping Areas
For alternating electric fields, the guide-
lines issued by the VDB e.V., Germany,
require a detailed analysis of the floating
potential electrical field in sleeping areas,
specifying nine points (three each in the
head-, torso- and foot area, with the out-
er edge of the instrument located 10 cm
off the bed’s edge). The NFA in combination with NFAsoft
allows for a “guided measurement” in order to efficiently ac-
complish data collection and evaluation.
