9.3. MANUAL CALIBRATION WITH ZERO/SPAN VALVES
There are a variety of valve options available on the GFC7001T/GFC7001TM for
handling calibration gases (see Table 1-1 for descriptions of each).
Generally performing calibration checks and zero/span point calibrations on analyzers
with these options installed is similar to the methods discussed in the previous sections
of this section. The primary differences are:
On instruments with Z/S valve options, zero air and span gas is supplied to
the analyzer through other gas inlets besides the sample gas inlet.
The zero and span calibration operations are initiated directly and
independently with dedicated buttons (CALZ & CALS).
9.3.1. SETUP FOR CALIBRATION USING VALVE OPTIONS
Each of the various calibration valve options requires a different pneumatic setup that is
dependent on the exact nature and number of valves present.
