Description
The current temperature reading of the electronics temperature
sensor.
The current voltage reading of the electronics temperature sensor.
This initiates a blowback cycle. 1=Do a manual blow back
The Calculated line frequency.
The calculated line voltage.
This is the maximum electronics temperature seen by the analyzer.
This resets the maximum temperatures.
See FF-891 section 5.3.
The time between automatic calibrations of the O
The value of the O high test gas. This gas is also used as the low gas
2
for calibrating the combustibles sensor.
The value of the O low test gas.
2
The instaneous impedance value for the O
The O calibration constant.
2
This is the constant value calculated from the last failed O
calibration.
This is the slope value calculated from the last failed O
O heater duty cycle.
2
The impedance value that was calculated as a result of the current
successful O calibration.
2
The percent of range of the current O
The O calibration constant from the previous good calibration.
2
The impedance value from the previous good calibration.
The O calibration slope from the previous good calibration.
2
The value and status of the O
The High and Low range limit values, the engineering units code, and
the number of digits to the right of the decimal point for the O
ing.
See FF-903 Section 3.3.
The temperature of the O
