MODULE OPERATION
Data Plotter Function
The data plotter function plots measured data in a graph during
the process. Click Show Plot to activate the feature and open a
graph window. The measurement results of channel 1 are plotted
in orange curve with Y-axis scale on the left. In contrast, the meas-
urement results of channel 2 are plotted in blue curve with Y-axis
scale on the right. The Y-axis scales are automatically adjusted
according to measurement results by default, and users can set
the Y-axis scales manually. In X-axis, it can plot maximum 5000
measurements for each channel. The window only scrolls and plots
the latest 5000 measurements once it reaches the limit. It must be
noted of that the depiction of the X-axis does not represent the
actual measurement time, but is depicted in sequence according to
the data received by the GUI.
At the bottom of window, some graph operation tools are available,
including dragging, zooming in, layout configuration, axis setting,
saving, and cleaning chart.
When the device is connected successfully and the data plotter
function is activated, the plotting window starts to plot data in the
graph. The graph continuously plots data and retains the historical
data even if the plotting window is closed. The historical data
is cleared when Clear button is clicked or when the device is
disconnected.

Channel Configuration
The following measurement configurations: range selection, aper-
ture and NPLC, single mode, and Run and Stop, are separately
available for two channels of the ADMX3652. These settings can
be configured independently based on the measurement needs of
users.

Range Selection
There are four options for setting the measurement range: Auto,
0.2V, 2.0V, or 20V. Selecting one of these measurement options
results in the maximum input being within the selected range plus
10% tolerance. If the Auto option is selected, the ADMX3652
automatically switches the measurement range based on the input
voltage.
Note that the measurement range default factory setting is 2.0V.

Aperture and Number of Power Line Cycles
(NPLCs)
The aperture time is the period of time used for reading the input
signal. A larger aperture time results in a better resolution, and a
shorter aperture time results in a faster measurement speed and
a faster sampling data output rate. The unit used for specifying
aperture time with the ADMX3652 is in NPLCs.
Note that when the NPLCs are set differently and two channels
are continuously measured, the sampling data output rate of two
channels is determined by the slower one.
Figure 23. Aperture (NPLC) Selection
The aperture time options include 0.05, 0.1, 0.25, 0.5, 1, 10, or 100.
Note that the default factory setting for aperture is 10.
