8.2.6. Log Interval
The RLDS retains a data log of 100 measurements for
each zone. The log interval is the number of
minutes from 1 to 1440 between each log point. This
parameter can be changed from Zone Setup screen 1
(Figure 8-1).
The default setting for this parameter is 1440
minutes (24 hours). If the log interval time is set to 0,
then a measurement is recorded in the trend log after
every measurement cycle
. Therefore, after the trend
log is filled, it will contain the last 100 measurement
points for a zone. If you want the data logged less
frequently, increase this value.
It is important to remember that cycle time is
dependent on many factors, including the number of
zones being monitored, input line length, and the run
zeroing mode selected. Before changing this value it
may be useful to review the log data first using the
Trend screen to determine the nominal cycle time.
