Definition
ATTENTION The Carbon and Dewpoint selections will automatically set the first input actuation to
Carbon. The Oxygen selection will automatically set the first input actuation to Oxygen. Input 2 can be
any input actuation, but it is normally a type K, R or S thermocouple input, depending upon the probe type
selected. All calculations are performed by the Controller with Percent Carbon shown as the PV display.
The actual value of each analog input may be viewed on the lower display. For all Carbon Types, if the
value of Percent Carbon falls below 0.1% - such as can happen when the Carbon Probe voltage output
falls below 900 mVdc – then the Controller will continue to update the PV display, but the accuracy is
unspecified. Likewise, if the measured temperature falls outside of the specified ranges as noted above
for the Carbon, Oxygen and Dewpoint input types, then the Controller will continue to update the PV
display, but the accuracy is unspecified. For the Dewpoint algorithm, if the Carbon Sensor voltage falls
below 800 mVdc, then the Dew Point is calculated as if the sensor voltage was at 800 mVdc.
