Molecular weight of air (user-specified; default = 28.96469 g/mol)
Core process variable = Relative density
The following equation is used when the core process variable is relative density.
Relative density Equation 2-5:
RD = K0 + K1 ×  + K2 × 

RD
Relative density of process gas
K0, K1, K2
Calibration factors from the on-site calibration. If a two-point calibration was
performed, K1 is set to 0.
