The Calibration menu is used to calibrate zero and span. The calibration
menu is similar for the single, dual, and autorange mode as shown below.

The dual and autorange modes have two SO
"LO"). This allows each range to be calibrated separately. This is necessary
if the two ranges used are not close to one another. For example, a low SO
range of 10 ppb and a high SO

calibration, ensure 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".
