Model GFC7000TA Carbon Dioxide Analyzer

6.8.4. 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 0-1000 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 set the ranges press following keystroke sequence

SAMPLE Display

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).

NOTE

In DUAL range mode the LOW and HIGH ranges have separate slopes and offsets

for computing CO2 concentration.

The two ranges must be independently calibrated.
