Page 5: Introduction
Cambridge Sensotec Rapidox 1100L Oxygen Analyser Instruction Manual 1. Introduction The Rapidox 1100L oxygen analyser allows accurate oxygen analysis over the range 0.1ppm to 1% O using a special German-engineered ppm electrochemical oxygen cell. This special low range analyser is designed for applications where a traditional zirconia sensor is not suitable. -

Page 11: Rapidox Calibration
Cambridge Sensotec Rapidox 1100L Oxygen Analyser Instruction Manual Rapidox Calibration Once the unit is at temperature it may be necessary to calibrate the sensor. Full calibration is a simple procedure requiring only one or two gases. The two gas values are user-selectable and can be changed via the front keypad (2) or the communications software described in section 8, and the calibration values can be stored on file for later use. -

Page 14: Analogue Outputs
Cambridge Sensotec Rapidox 1100L Oxygen Analyser Instruction Manual Analogue Outputs The standard industrial analogue outputs (0-10V and 4-20mA) for both oxygen and pressure are accessible via the terminal block (6) on the rear panel. Note that the ranges of the 0-10V and 4-20mA are tied together so changing one alters the other. - Page 15 Cambridge Sensotec Rapidox 1100L Oxygen Analyser Instruction Manual To modify the oxygen analogue output range scroll down the menu to no.3 “Set Outputs” and press ENT. Edit the lower and upper values in exactly the same manner as described in 7.5 for setting the cal gas values. Once programmed the new values remain in the memory until they are edited again in the future.

2. Auto: This is the factory default setting. If the Auto mode is selected then the Rapidox 1100L uses the reading from the internal pressure sensor to correct the oxygen partial pressure and maintain an accurate concentration reading. - Page 18 Cambridge Sensotec Rapidox 1100L Oxygen Analyser Instruction Manual Figure 4: Rapidox default COM properties box Alternatively, the baud rate can be reduced to 57,600 or 9600 via the “Set Baud Rate” menu item, using the front panel keypad on the Rapidox. This setting is stored in EEPROM.
