OUTPUTS: This enables the rear panel relay outputs when ON is selected 2. - Page 15 Cambridge Sensotec Rapidox 1100ZR-H-PFC-E O Analyser Instruction Manual The Rapidox analyser provides various analogue outputs. The standard industrial analogue outputs (0-10V and 4-20mA) for both oxygen, and temperature (or internal pressure) are accessible via the terminal block (6) on the rear panel.
- Page 16 Cambridge Sensotec Rapidox 1100ZR-H-PFC-E O Analyser Instruction Manual 2. LOG (ppm): This setting produces an output that is scaled logarithmically between 0V and 10V (or 4 and 20mA). So, for example, if the scale is set to 0V = 0.0001% (1 ppm) and 10V = 100% (1000000 ppm) then 5V would indicate an oxygen reading of 0.1% (1000 ppm).
- Page 17 Cambridge Sensotec Rapidox 1100ZR-H-PFC-E O Analyser Instruction Manual 3. RAW (mV): This setting is for certain customers who like to monitor the raw sensor EMF signal. The signal from a sensor goes from approximately -50mV at 100% O through zero at approx 5% O and to +1000mV at extremely low O levels.

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 eight minutes then the analyser will give up and indicate that the internal heater has failed and the sensor needs replacing. -
