Zero and Span calibrations using the Zero/Span Valve option are
similar to that described in Section 7.1, except that:
Zero Air and Span Gas is supplied to the analyzer through the Zero Gas and
Span Gas inlets rather than through the Sample inlet.
The Zero And Cal operations are initiated directly and independently with
dedicated keys (
CALZ
&
CALS
).
