5.4.3.2. RNGE MODE DUAL: CONFIGURING THE T803 ANALYZER FOR DUAL
RANGE MODE
Selecting the DUAL range mode allows the A1 and A2 outputs to be configured
with different reporting ranges. The analyzer software calls these two ranges
RNG1 (low) and RNG2 (high).
The C2L RANGE 1 setting corresponds with the analog output labeled A1 on the rear panel of
the instrument.
The C2H RANGE 2 setting corresponds with the A2 output.
In DUAL range mode the RANGE test function displayed on the front panel will
be replaced by two separate functions:
CO2 RN1: The range setting for the A1 output.
CO2 RN2: The range setting for the A2 output.
To select the DUAL range mode press following touchscreen button sequence
.

When the instrument’s range mode is set to Dual the concentration field in the
upper right hand corner of the display alternates between displaying the low
range value and the high range value. The concentration that would be displayed,
is identified as follows: ”C2L” = LOW (or A1) and ”C2H” = HIGH (or A2).
Note
In DUAL range mode O2L and O2H have separate slopes and offsets for
computing O

concentrations. The two ranges must be independently
calibrated.
