The process gas consists of multiple gas concentrations. The iEFM operation
requires that each gas element percentage of concentration be entered for valid
measurements. Enter the percentage values in decimal form using the gas
calibration menu shown in Figure 3-20 below, which is accessed by selecting the
Gas Cal tab. When all values are entered, hit the Set Calibration button to
accept the values.
