Background screens are used to adjust the
instrument zero 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 precise the calibration results. To achieve
maximum precision, allow the instrument to stabilize each time input gas is
changed and set the averaging time to 300-second averaging.
