Channel Information Region
Channels can return values in units of °C, °F, °K, °R, mV, V, or user
defined units (if the mX + b option is used). With exception of mX + b
user defined-units, units depend on the configuration and type of
signal conditioning card used. Signal conditioning cards are detailed
in the user’s manual for you data acquisition device. The Channel
Information Region is located on the right-hand side of ChartView’s
main window. The values displayed in this region are the real-time
values of the selected channel.
By clicking on the up or down arrows by the channel selection box
(item 14), you can select one (of a maximum of 4 channels) that were
assigned to a chart. You could then observe the chart-related
information of the chosen channel.
You can also select a new channel for the information region by placing the cursor in (or tabbing over
to) the “Center” or “Units/Div” fields and then pressing PageUp or PageDown. This is particularly
useful when your main window has been re-sized such that the channel selection boxes are not visible.
The following list identifies the various areas of the region.
13 Chart Max. Scale Value
(Grid Limit Line)
17 Center
(Value at chart mid-line)
14 Channel Selection
(Of chart’s available channels)
18 Units/Division
(Provides the vertical increment of one grid box.)
15 Multiply (x2) 19 Chart Min. Scale Value (Grid Limit Line)
16 Present Value 20 Divide (÷2)
Note: The basic ChartView program does not permit overlapping channels or having more than
one chart group. Multiple group applications (ChartView Plus) can be activated by use of a
special code, allowing up to four overlapping channels per chart. Regardless of whether you
are using the basic ChartView program, or ChartView Plus, there is a maximum limit of 16
charts per group.
Multiply and Divide Buttons - In addition to reading channel values, you can increase or decrease the
size of the selected channel’s chart. This is accomplished with the Multiply (15) and Divide (20)
push-buttons. The Multiply push-button effectively increases the size of the selected channel’s chart
by a factor of two, while automatically adjusting the chart’s high and low values (items 13 and 19).
Aside from “clicking” on the Multiply/Divide controls, you can use your keyboard spacebar to control
this feature once the button (15 or 20) is selected. Selection may be with mouse, or by tabbing over to
the control.
Making changes to a channel’s chart parameters does not affect the parameters of the other channels,
with the following exception: Holding the keyboard’s control key down while adjusting either spinner
for center (item 17), or spinner for units/div (item 18) causes the parameter change to apply to all
channels displayed for the chart, not just the currently selected channel display. This feature applies to
the spinners and keyboard up and down arrow keys, but not to the text input.
Center Control - The Center control (item 17) changes the value of the selected channel’s chart
centerline. Changing the value of center results in an automatic change of the chart’s high and low
end values (items 13 and 19), and possibly an automatic change of the units/div (item 18). Aside from
using the center spinner controls to change center, you can change the center value by placing the
mouse cursor in (or tabbing over to) the field and then either typing in the desired value, or using the
PC keyboard up and down arrow control keys.
