5.2 GROUP CONFIGURATION
Group configuration is separated into two areas, one which defines trending characteristics (for display
channels) the other defining the recording characteristics for saving data to the Flash memory ready for
archiving.
5.2.1 Group Trend configuration
This allows the user to define which points are to be traced on the display and at what interval, and also
allows the number of chart divisions to be set up. Figure 2.3.1 shows a typical configuration page.
Note: The background chart colour is set up as a part of Instrument Display configuration.

Descriptor Allows the user to enter a descriptor (20 characters max.) for the group.
Interval The trending interval which defines how much data appears on one screen height
or width. A number of discrete intervals can be chosen between 0.125 seconds to 1
hour. The selection should be made according to how much detail is required, and
how much data is to be visible on the screen.
Major Divisions Allows the user to select the number of divisions into which the scale is divided and
how many gridlines are displayed. Setting the value to 1 results in just the zero and
full scale values appearing. Setting the value to 10 (the maximum) results in a scale
with zero, full scale and nine intermediate values appearing, with associated grid
lines.
Point1 to Point6 Allows the user to select which channels and virtual channels are to be traced. The
maximum number of traces is six.
