Cambridge Sensotec Rapidox 1100ZR3-H-PFC O Analyser Instruction Manual Notes: The current outputs are active self-powered outputs - they are not loop powered i.e. they are current source outputs. The voltage (0 to10V) outputs produce non-zero voltages during start-up, fault and over/under range conditions - if 1V to 5V outputs are required, with these conditions indicated by corresponding voltages between 0V and 1V, the current outputs can be used, with a 250 Ohm load resistor. -

If so then the heater may be struggling to heat the sensor with such cooling gas present. Does the problem go away if room air is allowed into the analyser? Contact Cambridge Sensotec for advice. If the message continues for around ten minutes then the analyser will give up and indicate that the internal heater has failed and the sensor needs replacing. -

The D term is a ‘damping’ factor that attempts to prevent the reading overshooting the set-point. It is a very sensitive parameter that if incorrectly adjusted can introduce wild oscillations in the oxygen reading.
