6.7.2Replacing the Nitric Oxide Sensor Bias Battery

A single lithium battery, located on the Nitric Oxide printed circuit board (see Figure 6-2), applies a constant bias voltage to the Nitric Oxide sensor even while the instrument is turned off. This battery has a life expectancy of at least 2 years.

Replace the Nitric Oxide bias battery toward the end of its expected life.

Equipment Required:

•Bias Battery (See Section 8.0)

Procedure:

1.Remove the analyzer’s rear case and lay it aside (refer to Section 6.2).

2.Remove old battery from its holder (see Figure 6-2).

3.Insert the new battery (positive side facing upwards) into its holder.

4.Reassemble the analyzer.

5.Before powering up and using the instrument, allow the Nitric Oxide sensor to stabilize as described below. Recalibration of the Nitric Oxide sensor is usually not required.

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 stabilization times are shown below. Generally, however, the sensor is sufficiently stable after 4 hours for measurement purposes.
