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.

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.

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.

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.
