Adjusting Channel Setup for Channel 1

ChartView

and

ChartView

Plus

data channels can operate in one of two modes: Units Full Scale or,

Units/Div. The mode is selected by radio button.

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.

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.

The channels (in the display) will be enabled, and will appear in

ChartView’s

Main Window. The

Channels will overlap on their assigned Chart (for

ChartView

Plus

applications), and will be visible

when the applicable Group is selected. Only one group of charts can be viewed at a time.

It is important to understand that other channels (those not in the display setup) maintain their existing

configuration status. They are not affected by the edit of the configuration display.

You can enable additional channels from the Channel and Alarm Setup window. Enabling additional

channels allows you to acquire more data; however, it will not change your display on

ChartView’s

Main Window. In other words, you can acquire data from channels you do not monitor.
