Default Storage
In addition to Delta points, another form of data is also stored. Consider a
situation where there is virtually no change through time in measured
value from the probe. In this case, it is possible that almost no data would
be stored to the data file. To avoid the scenario of a long-term test
containing virtually no stored data, sparse linear sampling also occurs
whereby data points are stored to the data file every n measurements
regardless of the measurement comparisons that are occurring. This type
of data is called “default storage.” For example, if the Measurement
Interval is 10 minutes and you specify a Default storage every 6
measurements—as shown in the event test setup screen below—then
data will be logged every hour regardless of the Delta comparisons.
