10.3.4.4 Output Processing and NAN
When a measurement or process results in NAN, any output process with
DisableVar = FALSE that includes an NAN measurement, e.g.,
Average(1,TC_TempC,FP2,False)
will result in NAN being stored as final-storage data for that interval.
However, if DisableVar is set to TRUE each time a measurement results in NAN,
only non-NAN measurements will be included in the output process. CRBasic
example Using NAN to Filter Data
(p. 431)
demonstrates the use of conditional
statements to set DisableVar to TRUE as needed to filter NAN from output
processes.
Note If all measurements result in NAN, NAN will be stored as final-storage data
regardless of the use of
DisableVar .
