DUAL RANGE MODE (DUAL)
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 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 0-1000 ppm
while the high range is set for 0-500 ppm.
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 select the
DUAL
range mode press following buttonstroke 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 currently being displayed is identified as
follows:
C1
=
LOW
(or
A1
) and
C2
=
HIGH
(or
A2
).
