Insert Comments directly into the Diagram
Areas of special interest can be commented directly in the plotted data.
Simply position your mouse, right click and enter your comments in the
comment window. Click Ok to have the comment embedded into the
data, marking an event or section of interest.
Program Window "Statistics Channels"
To display the data of a particular channel, click the triangle to the left
of the channel.
If multiple channels are open, an additional click on the channel infor-
mation will bold the channels plotted and statistical data.
The top five values are standard statistical values
value "Edges per hour" is used to analyse the number of steeply rising
edges, spikes, peaks, pulses, sharp bursts or high frequency transients
of the field. The edge thresholds can be defined in the Channel menu
under Set edge criteria. This is an experimental function.
PLEASE NOTE: If the 50 Hz high pass filter has been set with the help
of the configuration part of NFAsoft (maybe even as pre-setting), this
only applies to the channels "All3D", "AllX", "AllY", and "AllZ". Never-
theless, possible frequency components at 16.7 Hz will also be rec-
orded in the correspondent channel. In this case the sum of the fre-
quency specific channels may well be higher than that of "All3D".
The light-blue field underneath the statistical channel data represents
the frequency distribution of the measured intensities of the specific
channel ("Histogram"). It is self-scaling and can be interpreted as fol-
lows:
On the left side of the x-axis a formula calculates and plots how of-

ten the minimum value has occurred in a given time interval, and
similarly on the right side for the maximum value.
The largest bar marks the value most frequently measured. Very

low bars indicate a specific value very seldom measured.

This chapter explains NFAsoft specific functions. Standard software
functions are omitted.
Edit
"Copy all"
Copies the plotted data area as well as the drop-down of the "Statis-
tics/Channels" section into the buffer – from here it can be inserted di-
rectly into your measurement protocol at any point of your choice. This
is similar to a screen shot.
All other edit options are self-explanatory.

The 95th percentile is calculated heuristically. If the possible deviation ex-
ceeds 10%, it will be noted in parenthesis after the figure in absolute terms.
