56 Chapter 8: ChartView & ChartView Plus TempScan / MultiScan User's Manual
Groups, Charts & Channels
When starting the program with no configuration file present (see
Chapter 1 if necessary), a feature called
Chart Setup Wizard is
automatically activated to assist you with your display setup. To make
the best use of
Chart Setup Wizard you need to understand the
relationship of Groups, Charts, and Channels.
Group . “Group” refers to a group of charts. Note that ChartView
program makes use of one chart group. ChartView Plus allows up to 64
groups, depending on the capabilities of your PC, but can only display
one group at a time.
Chart . “Chart” refers to display area which reflects real-time channel
data values for a selected channel and can be scrolled at various rates.
You can assign up to 16 charts per group.
ChartView Plus enables each
chart to display up to four overlapping channels.
Channel . “Channel” refers to a signal channel. Channels will be
displayed in units of °C, °F, °K, °R, mV, V, or in user-defined units,
depending on the configuration and type of signal conditioning card
used. With
ChartView Plus you can have up to 4 overlapping channels
assigned to one chart.
Using ChartView
Charting vs. Acquisition To-Disk. ChartView has two distinct operations; displaying real-time data
and saving collected data to disk. These two operations are completely independent of one another. As
such, ChartView can display data in its real-time indicator without arming a "to-disk" acquisition, or it
can arm a "to-disk" acquisition without displaying the data in its real-time indicators.
Regardless of the state of the to-disk acquisition, when enabled, the real-time indicators, including the
charts, always display the current channel values. Regardless of whether the to-disk acquisition is
disarmed, waiting for trigger, or in the post-trigger state, the channel values viewed in the real-time
indicators always reflect the current values of the channels.
Hardware/Software Interaction & Stand-Alone Operation. The intelligent acquisition hardware
handles all aspects of the acquisition, including triggering, scan timing, and data buffering. ChartView
simply provides a method for the user to configure the data collection parameters and download them
to the hardware. Once the hardware is configured, it has the capacity to perform the acquisition
without computer intervention. As the instrument collects the data, it stores it in its internal buffer in
preparation for uploading it to the computer.
