Round
Rounds a value to a higher or lower number.
Syntax
variable = Round (Number, Decimal)
SGN
Finds the sign value of a number.
Syntax
x = SGN(source)
Sqr
Returns the square root of a number.
Syntax
x = SQR(number)
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superseded by PRTCalc() in most applications.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)
