The concentration calculation is defined as the process that transforms a
detector count into a displayed final concentration. The process is as
follows:
DETECTOR COUNT TRANSLAT ED INTO A STANDARD DET ECT OR CONCENT RAT ION
USING A DET ECT OR COUN T VS. DETECTOR CONCENTRATION CALIBRATION CURVE.
STANDARD DETECTOR CONCENTRATION IS CORRECTED TO A SPECIFIC GAS USING
T HE INSTRUMENT RESPON SE FACTOR.
SPECIFIC GAS CONCENT RAT ION IS BACKGROUN D C ORRECTED (IF ENABLED)
INSTRUMENT RESPONSE FACTOR AND BACKGROUND CORRECTED C ONCENTRA-
T ION IS RF CORRECTED USING THE CURRENT ROUTE ENTR Y RF (IF ANY)
