DATA_POINT

See description below
Depends on variables selected
Contains the data for the particular 15 minute average segment selected by
DATA_INDEX.
Set DATA_INDEX to the segment of stored data desired, then after about 1 second
this variable will be loaded with the data appropriate for that segment. If no data is
available for the particular segment, elements 0 and 5 will contain a large negative
number. The elements are as follows:
Primary variable (normally, but selected by TRENDCONT1)
Day of month
Hour
Minute
If > 9, calibration occurred; if 1 or 11, at least one invalid reading
Secondary variable (from TRENDCONT2)
The index where this data segment is stored, 0 - 95
Stored variables are selected by TRENDNAME, which shares data with
TRENDCONT to tell the analyzer which variables to store.
