4.3 Piping for System 3
Piping in System 3 is illustrated in Figure 4.10. In System 3, calibration is automated;
however, the piping is basically the same as that of System 2. Refer to Section 4.2.
Adjust secondary pressure of both the air set and the zero gas reducing valve so that these
two pressures are approximately the same. The ow rate of zero and span gases (normally
instrument air) are set by a single needle valve.
After installation and wiring, check the calibration contact output (see Sec. 7.11.2), and adjust
zero gas reducing valve and calibration gas needle valve so that zero gas ow is within the
permitted range. Next check span gas calibration contact output and adjust air set so that span
gas ow is within the permitted range.

When blow back function is used by contact input to the ZR402G converter, install blow back
piping as illustrated in Section 4.3.1.
NOTE
Blow back function means the function to get rid of dust inside a probe in a high temperature
probe adapter by using compressed air, when a high temperature detector is used.
