9.7. CALIBRATION OF OPTIONAL SENSORS
This section provides the calibration setup and procedures for the O
2
Sensor and the CO
2
Sensor options. Refer to any addenda accompanying this manual for custom
configuration information.
9.7.1. O
2
SENSOR CALIBRATION
Presented here are first the setup and then the calibration steps for the O
2
Sensor.
9.7.1.1. O2 PNEUMATICS CONNECTIONS
The pneumatic connections for calibrating are as follows:

SENSOR ZERO GAS: TAI recommends using pure N
2
when calibration the zero
point of your O
2
sensor option.
O
2
SENSOR SPAN GAS: TAI recommends using 20.8% O
2
in N
2
when calibration the
span point of your O
2
sensor option (See Table 3-12).
9.7.1.2. SET O2 SPAN GAS CONCENTRATION
Set the expected O
2
span gas concentration.
This should be equal to the percent concentration of the O
2
span gas of the selected
reporting range (default factory setting = 20.8%; the approximate O
2
content of ambient
air).
