Step 3) Spanning Oxygen

To span the Oxygen channel to ambient air choose the gas mix "Oxygen High".
The "Oxygen High" gas mix is defined for just Oxygen and no other gases are defined. This
allows for oxygen to be spanned without spanning CH4, CO, H2S, or H2 to Zero. Press
Check to begin checking the O2. As the gas is displaced from the previous Span in the
instrument the current value will rise.
