Setup for Span Gas Use (Full Start)
11. After pressing
NO
in step 5, the system
directs you to connect the span gas tank
to the appropriate inlet. After complet-
ing the process, press
ACK to continue.
12. The system directs you to connect the
sample gas tank to the appropriate inlet.
When done, press
ACK
to continue.
13. The system directs you to check the
flow rate for 150 cc/min and to press
ACK
when ready.
• With recommended sample gas pressure
(10–30 psig), the mass flow controller
will automatically control the flow at
150 ± 3 sccm. You may check the flow
by connecting a bubblometer at the
analyzer sample vent line to insure that
there is proper flow.
NOTE: Mass flow controller is preset to give 150 ± 3 sccm flow. However,
when a pneumatic valve does not open or the gas pressure drops to
a point where the mass flow controller is unable to deliver 150 sccm
flow, the analyzer will automatically shut down and display the
error message FLOW BELOW 20 SCCM. If this occurs, check the
sample/span gas and air pressure. Make sure that they are within
the recommended range.
14. After pressing
ACK
in step 13, the
system performs a purge-from-span,
and automatically continues to step 21.
