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 (Section 4.13.2),
•
By activating the instrument’s AutoCal feature (Section 5.8),
•
Remotely by using the external digital control inputs (Section 4.15.1.2) or Ethernet
option.
•
Remotely through the RS-232/485 serial I/O ports (Section 4.11).
All supply lines should be vented outside of the analyzer’s enclosure. In order to
prevent back-diffusion and pressure drop effects, these vent lines should be between 2
and 10 meters in length.
