Response Factors for Gases and Vapors
To use the response factors
1. Press the CAL key and enter the response factor for the specific compound.
2. Calibrate the DataFID with zero air and 500 ppm methane as described in the section on
calibration
3. Expose the DataFID to the sample. The displayed reading is the approximate concentration of
the specific compound.
The response factors on the INFICON web site serve as a guide to concentrations measured by the
DataFID.
NOTE: It does not matter which Cal Memory is selected or which response factor is entered, DataFID ’s
response is not specific to any one compound. The displayed reading represents the total concentration
of all ionizable compounds in the sample.
Preparing for Field Operation
