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.

After the gases are measured, the 7.3 valve, wash bypass

reagent manifold toward the inner sample port. The
sample pump is on.

The reagent and waste pumps remain on. The pre-segment
moves through the sample port into the waste and removes
any residual reagent in the manifold.
