Three Methods of %Carbon Calculation

The PGA 3510 is able to calculate %Carbon using one of three methods: Default Settings, IRF Matrix, or Equipment-Specific IRF Matrices.

1. Default Settings. This is the method used when Use IRF Matrix is set to False (off). The sample gas composition (%CO, %CO₂, %CH₄) and temperature, along with the programmed IR Shim Factor and CH₄ Factor, are used to arrive at a calculation of atmospheric %Carbon.

2. IRF Matrix. When Use IRF Matrix is set to True (on), the PGA 3510 will use values configured in the IRF Adjustment Matrix to set the current IR Shim Factor. Configuring the adjustment matrix is described in more detail in the IRF Adjustment Matrix section IRF Adjustment Matrix.

3. Equipment Specific IRF Matrices. This method allows you to configure an IRF Matrix specific to a configured piece of equipment and change the calculation method based on the equipment whose gas composition is being analyzed. This method is described in more detail in the Equipment Specific IRF Matrices section Equipment Specific IRF Matrices.
