be output at each update. Therefore, the lower the averaging time the faster
the front panel display and analog outputs respond to concentration
changes. Longer averaging times are typically used to smooth output data.
The Averaging Time screen for the single range mode is shown below. In
the dual and auto range modes, an Averaging Time Menu is displayed
before the averaging time screens. This menu is needed because the dual
and auto range modes have two averaging times (high and low). The
Averaging Time screen functions the same way in the single, dual, and auto
range modes. The following averaging times are available: 1, 2, 5, 10, 20,
30, 60, 90, 120, 180, 240, and 300 seconds.

The Calibration Factors menu displays the calibration factors, which are
used to correct the CO
2
readings that the instrument generates using its
own internal calibration data. The screens below show the calibration
factors menu in single mode and dual/auto range modes. The only
difference between the screens are the words “LO” and “HI” to indicate
which range is displayed. The O
2
Background menu item and the O
2
Coefficient menu item are displayed only when the internal O

sensor
option is installed.
Normally, the calibration factors are calculated automatically using the
functions described in “
Calibration Menu
” later in this chapter. However,
the calibration factors can also be set manually using the functions in this
menu.
