Maintenance
12. Plug the sensor into analyzer; and then reattach tubing to gas cup.
13. Install the sensor retainer and battery cover.
12. Allow the sensor that was just installed time to stabilize in the circuit
before continuing with this procedure. Stabilization time for all sen-
sors (except for the NO sensor) is about 1 hour. The NO sensor baseline
technically requires several days to stabilize but should be sufficiently
stabilized for use in approximately 4 hours.
13. Turn ON the analyzer and confirm that no sensor errors occur during
warm up.
Note: Discard an old sensor in accordance with local and federal haz-
ardous waste disposal laws.
14. Calibrate the new sensor(s) per Section 5 (except the O2 sensor which
does not require calibration).
