Appendix A. CRBasic Programming Instructions
Syntax
PRT(Dest, Reps, Source, Mult)
PRTCalc
Calculates temperature from the resistance of an RTD according to a range of
alternative standards, including IEC. Supercedes PRT() in most applications.
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.7.9 Spatial Processing
