Appendix A. CRBasic Programming Instructions 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) Read More! See Wind Vector (p. 189). 456
