Operating Instructions Model GFC7000TA Carbon Dioxide Analyzer
Teledyne Analytical Instruments 92
6.8.3. Single Range Mode (SNGL)
This is the default reporting range mode for the analyzer. In single range mode both A1 and A2 are set to
the same reporting range. This reporting range can be any value between 50 ppm and 2 000 ppm.
While the two outputs always have the same reporting range, the span, signal offset and scaling of their
electronic signals may be configured for differently (e.g., A1 = 0-10 V; A2 = 0-0.1 V). See Section 6.13.4
for instructions on adjusting these parameters.
To select SNGL range mode and to set the upper limit of the range, press:
