ASVC Kn S640 a Output of values of the MLT concentration formula
Concentration formula:
Conce = FacP * FacT * FacSpan * Lin{(RawAvg - OffP - OffT - OffX) * RGain * Gain}
Meaning of the variables:
RawAvg: Raw value average (including t
90
time)
OffP: Offset correction of physics
OffT: Offset correction of temperature
OffX: Offset correction of interferences from other channels
RGain: Analog pre amplifying factor (BIS)
Gain: Factor standardizing to the desired setpoint value (span)
Lin: Linearization procedure
FacSpan: Span factor standardizing the product "FacP*FacT*FacSpan" to 1.0 during the span cal.
FacT: Temperature correction in the sensitivity
FacP: Pressure correction in the sensitivity
Conce: Concentration value
Syntax: ASVC Kn S640 a
Response: ASVC 0 <value1> <value2> ...
a = 0: value1 = RawCount = uncorrected signal
value2 = RawAvg
value3 = OffT
value4 = OffX
value5 = OffP
value6 = Gain
value7 = RGain
a = 1: value1 = LinInput = (RawAvg - OffP - OffT - OffX) * RGain * Gain
value2 = LinOutput = Lin{(RawAvg - OffP - OffT - OffX) * RGain * Gain}
value3 = FacSpan
value4 = FacT
value5 = FacP
value6 = Conce
a = 2: value1 = Temperature for OffT
value2 = Temperature for FacT
value3 = Atmospheric pressure for FacP
