Prepare a mild soap solution Use warm water and dish washing detergent Borax hand soap or a similar soap Soak the sensor for 2 to 3 minutes in the soap solution 4 Use a small bristle brush cotton swab Q tip or pipe cleaner to scrub the entire measuring end of the sensor thoroughly cleaning the electrode surfaces lf detergent solution cleaning cannot remove surface deposits use mu riatic acid or another dilute acid to dissolve the deposits The acid should be as dilute as possible but yet strong enough to clean Experience will help determine which acid to use and how dilute it can be Some stubborn coatings may require a different cleaning agent For assistance in these difficult cases contact the OMEGA Service Depart ment Before cleaning with acid determine if any hazardous reaction products could form Example A sensor used in a cyanide bath should not be put directly into a strong acid for cleaning because poisonous cyanide gas could be produced Acids are hazardous Wear appropriate eye protection and clothing in accordance with Material Safety Data Sheet recommendations Soak the sensor in dilute acid for no more than 5 min utes Rinse the sensor with clean warm water and then place the sensor back into the mild soap solution for 2 to 3 minutes to neutralize any remaining acid 5 Rinse the sensor in clean warm water 6 Calibrate the analyzer using the procedure in the ana lyzer instruction manual If

Interconnect Cable The OMEGA interconnect cable part number CDE3600 Details CAB is provided with unfinished ends since it must often be shortened during installation The CDE3600 CAB cable is very similar to the sensor s integral cable except that it has two additional conductors green and yellow which are not required When stripping the interconnect cable during ter mination purposely cut off these green and yellow wires from each end of the stripped back cable This ensures the same wire color coding used by the sensor s integral cable NOTE OMEGA strongly recommends using only its CDE3600 CAB interconnect cable If a different ca ics ble is used it must have equivalent construction four conductors and two separate isolated shields one shielding the signal and one shielding the overall cable These specific cable characteristics protect the measurement signal from electromag netic interferences Using a cable with different construction PART TWO INSTALLATION BARE SENSOR SHIELD WIRE SHRINK TUBING OR TAPE APPROX 1 INCH LONG OUTER CABLE JACKET OUTER SHIELD FOIL CELLOPHANE BINDER INNER SHIELD FOIL SECTION 3 SENSOR INTERCONNECT CABLE DETAILS may interfere with the measurement systems ability to properly measure To correctly terminate the ends of the interconnect cable refer to Figure 2 4 and follow this procedure 1 Carefully strip back 2 1 4 inches of the outer cable jacket the outer s
