Location Descriptor describes the location of the field mill. When the software is configured to
display data from multiple field mills the descriptor is important in identifying the source of the data.
The History Graph shows the most recent data in graphical form. The history graph is useful in
identifying trends in electric field.
Zoom Handles are used for zooming in on an area of interest in the trend graph. There are zoom
handles for magnifying the display horizontally (the time axis) or vertically (the amplitude axis.) Click
and drag a zoom handle to adjust
The Current Field Reading is the amplitude of the electric field at the present time. The current
field reading is updated approximately once per second.
The Time Range Selector is used to change the scale of the horizontal scale axis.
The Amplitude Range Selector is used to change the scale of the vertical amplitude axis.
