3. 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
2
and pCO
2
are measured.
The CO-ox pumps starts to prevent contamination of the
sample connector by ambient air.
