PeakValley
Detects maxima and minima in a signal.
Syntax
PeakValley(DestPV, DestChange, Reps, Source, Hysteresis)
Sample
Stores the current value at the time of output.
Syntax
Sample(Reps, Source, DataType)
SampleFieldCal
Writes field calibration data to a table. See Calibration Functions
(p. 500).
SampleMaxMin
Samples a variable when another variable reaches its maximum or minimum for
the defined output period.
Syntax
SampleMaxMin(Reps, Source, DataType, DisableVar)
StdDev
Calculates the standard deviation over the output interval.
Syntax
StdDev(Reps, Source, DataType, DisableVar)
Totalize
Sums the total over the output interval.
Syntax
Totalize(Reps, Source, DataType, DisableVar)
A.2.3.2 Multiple-Source
ETsz
Stores evapotranspiration (ETsz) and solar radiation (RSo).
Syntax
ETsz(Temp, RH, uZ, Rs, Longitude, Latitude, Altitude, Zw, Sz,
DataType, DisableVar)
RainFlowSample
Stores a sample of the CDM_VW300RainFlow into a data table.
Syntax
RainFlowSampe(Source, DataType)
WindVector
Processes wind speed and direction from either polar or orthogonal sensors. To
save processing time, only calculations resulting in the requested data are
performed.
Syntax
WindVector(Repetitions, Speed/East, Direction/North,
DataType, DisableVar, Subinterval, SensorType, OutputOpt)
