The Calibrate CO Coefficient screen is used to adjust the CO coefficient
and enter the span concentration. The display shows the current CO
concentration reading. The next line of the display is where the CO
calibration gas concentration is entered.
The CO span coefficient is calculated, stored, and used to correct the
current CO reading. For more information about calibration, see Chapter
4, "Calibration". In dual or auto range modes, "HIGH" or "LOW" is
displayed to indicate the calibration of the high or low coefficient.
In the Main Menu, choose Calibration > Cal Coefficient.
