9.10. Calibration of Optional Sensors
This section presents calibration procedures for the O
2
sensor option and for the CO
2
sensor option.
9.10.1. O
2
Sensor Calibration
Calibration begins with connecting the zero and span gases, then setting the
concentration values.
9.10.1.1. O
2
Calibration Setup
Bottled gases are connected as follows:

O
2
SENSOR ZERO GAS: Teledyne Analytical Instruments recommends using pure N
2
when calibrating the zero point of your O
2
sensor option.
O
2
SENSOR SPAN GAS: Teledyne Analytical Instruments recommends using 20.9%
O
2
in N
2
when calibration the span point of your O
2
sensor.
9.10.1.2. Set O
2
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 = 20.9%; the approximate O
2
content of ambient
air).
