RNUMber
The reading number indicates the point index in the trace
buffer.
0001
The
RELative
and
RSTamp
elements are defined as the time since the first reading was stored in
the buffer. These values are reset every 24-hours. The
DATE
,
TIME
, and
TSTamp
elements
represent absolute time from the internal real-time clock (RTC).
