12. Allow the sensor that was just installed time to stabilize in the circuit
before continuing with this procedure. Stabilization time for all sensors
(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 old sensors in accordance with local and federal
hazardous waste disposal laws.
14. Enter the B-Smart
®
calibration code or calibrate the new sensor(s) as
explained earlier (see Calibration on page 66). An exception is the O
2
sensor which does not require calibration.
