The Calibrate O
2
Span Coefficient screen is used to enter the O
2
span
concentration and calibrate the O
2
span coefficient while sampling span gas
of known concentration. This button appears if the O
2
Sensor option is
selected in the configuration screen.
It is important to note the O
2
averaging time when calibrating. The longer
the averaging time the more precise the calibration results. To achieve
maximum precision, allow the instrument to stabilize each time input gas is
changed and set the averaging time to 300-second averaging. The O
2
Averaging Time is located at Settings>Measurement Settings>Averaging
Time.

Span Coefficient (single range
mode)
The Calibrate O
2
Span Coefficients screen contains the following
information:
●
Edit O
2
Span Concentration: User enters the O
2
span concentration.
●
Current O
2
Concentration: Read only. Current O
2

reading.
●
Current O
2
Span Coefficient: Read only. Current O
2

value.
●
Calculated O
2
Span Coefficient: Read only. After the “Edit O
2
Span
Concentration” value is entered, the new calculated O
2
span coefficient
is displayed.
●
Calibrate: When pressed, updates the O
2
coefficient and the O
2
concentration should match the span concentration.
