Data Displayed on Console
The data display categories represent all weather variables that the console displays and are listed in alphabetical
order. General describes the general ways in which data is displayed and archived for all data display categories and
is listed first as a point of reference. See the individual data display categories for specific display information.

Current Display Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . Current display data describes the current reading for each weather
variable. In most cases, the variable lists the most recently updated
reading or calculation. Some current variable displays can be
adjusted so there is an offset for the reading.
Current Graph Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Current graph data appears in the right most column in the console
graph and represents the latest value within the last period on the
graph; totals can be set or reset. Display intervals vary. Example
include: Instant, 15-min., and Hourly Reading; Daily, Monthly, High
and Low
Historical Graph Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . Includes the past 24 values listed unless otherwise noted; all can be
cleared and all totals reset. Display intervals vary. Examples include:
15-min., and Hourly Reading; Daily, Monthly, High and Low
Graph Time Interval Length . . . . . . . . . . . . . . . . . . . . . . . 1 min., 10 min., 15 min., 1 hour, 1 day, 1 month, 1 year (user-
selectable, availability depends upon variable selected)
