After the wash segment moves through the measurement
module, the Cal gas and diverter valves open and Cal gas
flows into the inner sample port. The sample pump
aspirates the Cal gas at a controlled rate through the
measurement module where pO

and pCO
2
are measured.

The Slope gas valve opens and Slope gas flows into the
inner sample port. The sample pump aspirates the Slope
gas at a controlled rate through the measurement module
where pO

are measured. The CO-ox pumps
starts to prevent contamination of the sample connector by
ambient air.
