Page 3: Introduction
The Clark & Optical cells can be interchanged in the O2X DUO sensor but an air calibration must be preformed. There is a connector on the electrode for the O2X amplifier cable. -
Page 4: Unpacking The Sensor
Damages If damages occurred during shipment, immediately contact the forwarder as well as your Cerlic representative. The shipment can be returned only after contact has been made with Cerlic. Packaging The original packaging is designed to protect the equipment and should be used for storage or if the goods must be returned. -
Page 5: Mounting The Sensor
Dielectric paste can be applied to the connector for corrosion protection. The O2X DUO sensor is mounted on a telescopic fibreglass rod and placed in a mounting bracket that fastens to a handrail, please refer to the Appendix 1 for further details. -
Page 6: Removing The Sensor
Removing the sensor The SS sensor housing may not be opened except by Cerlic service personnel. Opening the sensor housing will void factory warranty. The sensor is removed in the following steps: • Disconnect the sensor cable from the BB1/BB2 control box and the flushing hose from the solenoid. -
Page 7: Installing A New Electrode/Cell
• If a new electrode is not to be installed, then the yellow plastic cap shall be mounted to protect the electrode connection plug and the flushing nozzles on the sensor. Installing a new electrode/cell: • Loosen and remove the SS flushing head. •... -

Flushing Flushing tube Sensor cable • Select the O2X DUO sensor in the Main Menu by using the buttons, • Press ENTER for five seconds to enter the Sensor Menu. • Use the arrows to select “Cleaning” and press ENTER. -
Page 9: Cleaning The Flushing Nozzle
By simultaneously pressing and ENTER you change between BB1/BB2 main menu and the sensor information display for the selected sensor. O2X DUO sensor has two information displays, the first menu shows: measured DO value, current temperature of the electrode in air, the solubility DO value in air for this air temperature, and the “slope”... -

If the selected sensor is not active (the text No transmitter is shown) a warning is displayed that asks you to make another choice in order to show the sensor menu. -
Page 11: Cleaning
Cleaning Press ENTER to go to Cleaning program Cleaner ”None”, ”Flush”, or ”Brush”. Do not select “Brush” since this does not exist for the O2X sensor Interval min 0--999 minutes, time between cleaning cycles Length sec 0--999 seconds, duration of flushing cycle Freeze sec 0--999 seconds, extra freeze time of output signal after a flushing cycle so sensor can go back to the orginal values. -
Page 12: Calibration
11. Calibration It is important that the instrument has been turned on for about 30 minutes prior to calibration so that the sensor and electronics can stabilize. Zero Calibration The sensor is zero calibrated at the factory, and does not need to be zero calibrated. We do however recommend to do a new zero calibration when replacing the electrode since half the job is then already done. -
Page 13: Air Calibrating A Sensor
An open plastic bag over the sensor may slow the calibration time down, but is otherwise a good way to help maintain constant conditions. • Select the O2X DUO sensor in the Main Menu by using the buttons. -
Page 14: Air Pressure Conversion
Air pressure conversion It is important to enter the correct air pressure before doing an air calibration. Air pressure is measured in mBar (which is exactly the same as the SI-unit hPa). Below is a formula and a table to convert from inHG to mBar (and thus to hPa). InHg mBar / hPa 29.2... -
