7.4. 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 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)
STEP ONE: Connect the sources of zero air and span gas to the respective ports on the rear panel
(Figure 3-2) as shown below.
