The cell voltages in the Control Panel can be configured
to stop updating automatically, and only be updated when
the Read Voltages button is clicked (as shown in Figure 5).
This provides the ability to freeze the data for a board at
any instant in time.

An alternative method of viewing the data is available by
pressing the Graph Data button, to open the Graph View
Window. The Graph View Window is detailed in Figure 30,
and allows data for each board and the stacked system to
be graphed over time. The graph data can be saved and
are reloaded later, and the View Options control allows
configuration of the Graph Display. The Stack Summary
provides graphed data for the entire system, where the
Board Summary, Cell Voltages, and Temperatures allow
data to be graphed for boards selected in the Tree View.
Up to 15 values may be graphed at one time, and the graph
is limited to 500 seconds of data.
The Global Channel Monitor tab switches the Control
Panel to a grid view in which all of the cell voltages can
be viewed at the same time. Disabled cells will be color
coded as grey, and cells selected in the System Tree View
will be highlighted in blue. Details of the Global Channel
Monitor View are provided in Figure 27.
Several controls are available on the Control Panel Cell Tab
for issuing balancing commands to the selected board.
In the Balance Mode Select Boxes, you can manually
select which cells are to be discharged by clicking the
cell's DISCHARGE button, which cells are to be charged
by clicking the cell's CHARGE button.
Figure 6. Balance Mode Select Boxes
Note that if a cell is disabled, the balance mode select
box will not be selected and the cell pictured will be grey.
Balancing and overvoltage conditions are also indicated
by color, according to the Cell State Color Key.
