Trending
allows you to determine whether a particular variable is
approaching a value of concern. It is like a “predictive” alarm. If the
number you enter in the first edit box is lower than the number you enter
in the second box, the data logger will check for an upward trend.
Likewise, if the number in the first edit box is higher than the number you
enter in the second box, the data logger will check for a downward trend.
The third edit box is used to indicate the maximum period of time that
may elapse before this alarm is no longer valid.
