In AUTO range mode, the analyzer automatically switches the reporting range between
two user-defined ranges (low and high). The unit will switch from low range to high
range when the SO concentration exceeds 98% of the low range span. The unit will

return from high range back to low range once both the SO
75% of the low range span.
In AUTO Range mode the instrument reports the same data in the same range on both
the A1 and A2 outputs and automatically switches both outputs between ranges as
described above. Also, the RANGE test function displayed on the front panel will be
replaced by two separate functions:
•
RANGE1: The LOW range setting for all analog outputs.
•
RANGE2: The HIGH range setting for all analog outputs.
The high/low range status is also reported through the external, digital status bits (refer
to Section 8.1.1).
To set individual ranges press the following control button sequence.

In AUTO range mode, the LOW and HIGH ranges have separate slopes
and offsets for computing SO
