The state of the zero/span valves can also be controlled by any of the following means:
•
manually from the analyzer's front panel by using the SIGNAL I/O controls
located within the DIAG Menu (refer to Section 5.9.1)
•
by activating the instrument's AutoCal feature (refer to Section 9.8)
•
remotely by using the external digital control inputs (refer to Section 8.1.2 and
Section 9.7.1)
•
remotely through the RS-232/485 serial I/O ports (refer to Appendix A-6 for the
appropriate commands)
Sources of zero and span gas must be capable of supplying at least 1.55 L/min.
(maximum 2.5L/min). The supply line should be vented outside of the analyzer's
enclosure. In order to prevent back-diffusion and pressure effects, these vent lines
should be between 2 and 10 meters in length.
Figure 3-21 shows the internal, pneumatic connections for the analyzer with the IZS
option installed.
