The Calibrate CO Background screen is used to adjust the instrument zero,
or background. Before making an adjustment, be sure the analyzer samples
zero air for at least 5 minutes.
It is important to note the averaging time when calibrating. The longer the
averaging time, the more accurate the calibration will be. To be most
accurate, use the 300-second averaging time. For more information about
calibration, see Chapter 4, "Calibration".
In the Main Menu, choose Calibration > Cal CO Background.

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 and the current CO range. 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.
