The state of the zero/span valves can also be controlled:
 Manually from the analyzer’s front panel by using the SIGNAL I/O controls located under the DIAG Menu
(refer to Section 6.9.2),

By activating the instru
ment’s AutoCal feature (refer to Section 8.8),
 Remotely by usin
g the external digital control inputs (refer to Section 7.3.1.2 and Section 8.7.1), or
 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 650 cm
3
/min (maximum 2.5L/min. Both
supply lines 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.
