Information

- Historical Data: Includes the past 25 values plus the current value listed unless otherwise noted; all can
be cleared and all totals reset
- Daily Data : Includes the earliest time of occurrence of highs and lows; period begins/ends at 12:00 am
- Monthly Daten: Period begins/ends at 12:00 am on the first of the month
- Yearly Data :Period begins/ends at 12:00 am on the first of January unless otherwise noted
- Current Data: Current 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
- Graph Time Interval: 10 min., 1 hour, 1 day, 1 month, 1 year (user-selectable, availability depends upon
variable selected) (2.5 seconds for Last 25 Wind Speeds)
- Graph Time Span: 26 Intervals (Current Interval plus 25 past values included; see Graph Intervals to
determine time span)
- Graph Variable Span (Vertical Scale) : Automatic (varies depending upon data range); Maximum and
Minimum value in range appear in Weather Center
- Alarm Indication : Alarms sound for only 2 minutes (except for time) if operating on battery power.
Alarm message is displayed in Weather Center as long as threshold is met or exceeded. Alarms can be
silenced (but not cleared) by pressing the DONE key.
- Transmission Interval : Varies with transmitter ID code from 2.25 seconds (#1=shortest), to 3 seconds
(#8=longest)
- Update Interval : Varies with sensor - see individual sensor specs
