Channel Information Region
By clicking on the up or down arrows (
σ
, or
τ
) by the channel selection box (item 11), you can select
one of a maximum of 4 channels that were assigned to that chart. You could then observe the chart-
related information for that specific 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.
(10) Chart Max. Scale Value (Grid Limit Line)
(11) Channel Selection (Of chart’s available channels)
(12) Multiply (x2)
(13) Present Value
(14) Center(Value at chart mid-line)
(15) Units/Division (Provides vertical increment of one grid box.)
(16) Chart Min. Scale Value (Grid Limit Line)
(17) Divide (
÷
2)
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 (12) and Divide (17)
push-buttons. The Multiply push-button effectively increases the size of the selected channel’s chart by
a factor of 2, while automatically adjusting the chart’s high and low values (items 10 and 16). Aside
from “clicking” on the Multiply/Divide controls, you can use your keyboard spacebar to control this
feature once the button (12 or 17) 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
(
σ
/
τ
) for center (item 14), or spinner for units/div (item 15) 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 14) 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 10 and 16), and possibly an automatic change of the units/div (item 15). 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.
Units/div - The units in units/div (15) can be °C, °F, °K, °R, mV, or V. The division referenced is one
vertical grid. In the example above for Channel 1, each vertical grid increment represents 0.1231°C
per division. Changing the units/division spinner controls (
σ
/
τ
) will result in an automatic adjustment
of the max scale and min scale values (items 10 and 16). Aside from using the units/div triangular
controls to change the value, you can change units/div from the Display Configuration Setup dialog box
as described on page 149.
