A.6.8 Integrated Processing
DewPoint
Calculates dew point temperature from dry bulb and relative humidity.
Syntax
DewPoint(Dest, Temp, RH)
PRT
Calculates temperature from the resistance of an RTD. This instruction has been
superseded by PRTCalc() in most applications.
Syntax
PRT(Dest, Reps, Source, Mult)
PRTCalc
Calculates temperature from the resistance of an RTD according to a range of
alternative standards, including IEC.
Syntax
PRTCalc(Dest, Reps, Source, PRTType, Mult, Offset)
SolarPosition
Calculates solar position
Syntax
SolarPosition(Dest, Time, UTC_OFFSET, Lat_c, Lon_c, Alt_c,
Pressure, AirTemp)
SatVP
Calculates saturation‐vapor pressure (kPa) from temperature.
Syntax
SatVP(Dest, Temp)
StrainCalc
Converts the output of a bridge‐measurement instruction to microstrain.
Syntax
StrainCalc(Dest, Reps, Source, BrZero, BrConfig, GF, v)
VaporPressure
Calculates vapor pressure from temperature and relative humidity.
Syntax
VaporPressure(Dest, Temp, RH)
WetDryBulb
Calculates vapor pressure (kPa) from wet‐ and dry‐bulb temperatures and
barometric pressure.
Syntax
WetDryBulb(Dest, DryTemp, WetTemp, Pressure)
A.6.9 Spatial Processing
AvgSpa
Computes the spatial average of the values in the source array.
Syntax
AvgSpa(Dest, Swath, Source)
