6.4. MANUAL CALIBRATION WITH ZERO/SPAN VALVES
Zero and Span calibrations using the Zero/Span Valve option are similar to that described
in Section 6.2 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
buttons (CALZ & CALS)
STEP ONE: As shown below connect the sources of zero air and span gas to the
respective ports on the rear panel (Figure 3-2).
