5.4.3.2. DUAL RANGE MODE (DUAL)
Selecting Dual Range mode allows the A1 and A2 outputs to be configured with
different reporting ranges. The analyzer software calls these two ranges low and high.
The Low range setting corresponds with the analog output labeled A1 on the rear panel
of the instrument. The high range setting corresponds with the A2 output. While the
software names these two ranges low and high, they do not have to be configured that
way. For example: the low range can be set for a span of 0-150 ppb while the high range
is set for 0-50 ppb.
In DUAL range mode the RANGE test function displayed on the front panel will be
replaced by two separate functions:
range1: The range setting for the A1 output.
range2: The range setting for the A2 output.
To set the ranges press following control button sequence

IMPORTANT
IMPACT ON READINGS OR DATA
In DUAL range mode the LOW and HIGH ranges have separate slopes
and offsets for computing SO
2
concentration. The two ranges must be
independently calibrated.
