Note: You can remove channels by highlighting a channel(s) in the Select Channels box, and then
clicking on the Remove button. In the previous figure, CH7 (in the select box) is highlighted.
Clicking the Remove button would delete that channel from Chart1.
Note: When a chart contains overlapping channels which share values (such that their traces reside on
top of each other), the more recent channel will obscure the earlier channel. Note that the lower a
channel is on the display list, the more recent it is in regard to the display.
8. In the display area (on the left-hand side of the screen) click on a channel to check the channel’s
configuration and to re-configure the channel, if desired. The Display Configuration Setup Window
will appear similar to that in the following figure.
This screen contains two “radio buttons” for selecting the method of adjusting the display mode and
channel setup. It is the same screen that was discussed in the sub-section, Editing an Existing Display
Configuration. From this screen you need to choose Units Full Scale or Units/Div.
Adjusting Channel Setup for Channel 1
Units Full Scale. When Units Full Scale is selected, as depicted in the above figure, you can alter Y Max
and Y Min. These are the upper and lower limits of the Channel as they will appear on the chart when the
channel is selected. When you change either parameter, Y Center and Units/Division are automatically
adjusted. You can not directly adjust Y Center or Units/Division while “Units Full Scale” is selected. You
can change Y Max and Y Min by using the up and down arrows, or by highlighting the existing value,
typing in the new value, the pressing “Enter” on your PC keyboard.
Note: If the window size is changed, a chart operating in the Units Full Scale mode will maintain its full
scale setting across the chart.
Units/Div. When Units/Div. is selected you can alter Y Center and Units/Div. Y Center is the centerline
value of the chart when the channel is selected. Units/Div. is the vertical value of on chart grid increment.
When you change Y Center or Units/Div. Y Max and Y Min are automatically adjusted. You can not
directly adjust Y Max or Y Min while “Units/Div.” Is selected. You can change Y Center and Units/Div. by
using the up and down arrows, or by highlighting the existing value, typing in the new value, the pressing
“Enter” on your PC keyboard.
The Channels will overlap on their assigned Chart and will be visible when the applicable Group is selected.
Note that only one group of charts can be viewed at a time.
Note: If the window size is changed, a chart operating in the Units/Div. Mode will maintain its units per
division scale setting across the chart.
