Trip range

Interval samples are stored during the run
only when the pressure differential during
the interval exceeds a maximum span or
range. Sample storage starts when the
difference between an interval's maximum
and minimum measurements becomes
greater than the trip setpoint, and continues
at every interval until a subsequent interval's
difference becomes less than the trip reset.
Sample storage then stops until an interval's
difference again becomes greater than the
trip setpoint.

Sample Type

One of the following:

- Interval end, the last measurement made in the sample

interval

- Average of all measurements made in the sample interval

- Minimum of all measurements made in the sample interval

- Maximum of all measurements made in the sample interval

- Median of all measurements made in the sample interval,

the midpoint between minimum and maximum

- Average, minimum, and maximum of all measurements

made in the sample interval. This requires 3 records of
storage per logged sample set and reduces capacity by a
factor of 3.
