4. If using remote calibration feature:
• Connect zero gas to the ZERO IN port.
• Connect span gas to the SPAN IN port.
5. Otherwise, calibrati on gases m ust be Tee 'd into t he sample i nlet with appropriat e
valves.
6. Regulate the sample gas pressure between 2 and 50 psig sufficient to keep the front
panel flowmeter reading in an acceptable range (0.1 to 2.4 SLPM). For non-
pressurized sample or very low pressure, (less than 2 psig) vacuum service plumbing
is recommended.
7. If greater sample flow is required for improved response time, install a bypass in the
sampling system upstream of the analyzer input.
8. For optional vacuum application where the sample pressure is at atmospheric or very
low pressure, the instrument should be fitted with the vacuum service option. This
option locates the flow control valve on the exhaust side of the Micro-fuel Cell.
Note: Exhaust connections must be consistent with the hazard level of the constituent
gases. Check Local, State, and Federal laws, and ensure that the exhaust
stream vents to an appropriately controlled area, if required.
