Calibration factors are used to correct the CO concentration readings that
the instrument generates using its own internal calibration data. The
Calibration Factors menu displays the calibration factors. The screens below

modes.
Normally, the instrument is calibrated automatically using the Calibration
menu described in “Calibration Menu” later in this chapter. However, the
instrument can also be calibrated manually using the Calibration Factors
menu.
To manually calibrate the instrument, see “CO Backgrounds” and “CO
Span Coefficients” below for more information.
