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

CALIBRATION SETUP
Bottled gases are connected as follows:

when calibrating
the zero point of your O
2
sensor option.
O

SENSOR SPAN GAS: Teledyne API recommends using 20.9% O
2
in N

when
calibration the span point of your O

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).
