9.4. MANUAL CALIBRATION AND CAL CHECKS WITH THE
VALVE OPTIONS INSTALLED
There are a variety of valve options available on the T200 for handling calibration gases
(see Section 1.3 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.
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
).
9.4.1. 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. Refer to the following
diagrams for information on each or these valve sets.
