Set Edge Criteria (experimental!)
This feature is new and its intention is to facilitate profes-
sionals the discussion and analysis of "dirty electricity" be-
yond today's definition. Activate "Edge Display" in the menu
option "View" to use this function.
This function allows you to define a threshold value with
which a spike can be marked directly in the "Edge Display"
of the plot. This threshold can be selected individually for
every channel. Standard values have been pre-selected as
defaults.
ty between adjacent points in time by a user defined factor
or multiple.
Slope = Marks a rise of measured field intensity between
adjacent points in time by a user defined slope rate in V/m,
mG or nT per second. This is independent of the measuring
intervals. A hypothetical interval of 1 second would give that
increment. This permits to compare results recorded with
different recording intervals.
Absolute threshold = Marks a rise of measured field intensity
between adjacent points in time by a user defined threshold
level in V/m, mG or nT. Any rise beyond this absolute
threshold value will be marked.
The selected edge criteria will be graphically displayed on
the top of the plotted data section and will appear numeri-
cally in the field channel statistical data section under edges
per hour for that particular time span. All edge markings dis-
played appear in real time and allow for a quick visual analy-
sis.
