The mode field indicates the current mode of the analyzer. Usually, it shows "SAMPLE",
indicating that the instrument is in the sample mode. Manual span checking or calibration can
only be performed by pressing the buttons on the front panel labeled "CALZ", "CALS", or
"CAL". Automatic span check only occurs at the preset time. Dynamic span adjust can be
performed during automatic or remote span checks. Remote span adjustment is performed via a
command from the RS-232 or the external contact closure inputs. Calibration and span
adjustments are discussed in greater detail in Section 3.1. Table 2-2 lists all the possible modes
in the analyzer and their meanings.
