4. Re-install the Smart Sensor assembly.
5. Before powering up and using the analyzer, allow the Nitric Oxide
sensor to stabilize as described below. Note that recalibration of
the Nitric Oxide sensor is not required after replacing its bias
battery.
Depending on how long the Nitric Oxide sensor was without bias
voltage, the time required for the sensor to completely stabilize
varies from less than a minute to several days. Typical stabiliza-
tion times are shown below. Generally, however, the sensor is suf-
fi ciently stable after 4 hours for measurement purposes.
Bias battery removed for... Stabilization time
Less than 15 minutes Less than 1 minute
Less than 1 hour Less than 5 minutes
Less than 2 days Less than 4 hours
Greater than 2 days Up to 2 days
