9.4. MANUAL CALIBRATION WITH ZERO/SPAN VALVES
Zero and Span calibrations using the Zero/Span Valve option are similar to that
described in Section 7.2, except that:
Zero air and span gas are 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 and CALS)
STEP ONE: Connect the sources of zero air and span gas to the respective ports on the
rear panel (refer to Figure 3-1) as shown below.
